The Why's of Tommy's '93 Wrangler
This document explains why I performed the modifications I did to my
Jeep. They are listed in chronological order (that means that most of the really
good stuff is listed toward the bottom).
Click an item below and I'll explain why I did it
Jeep
purchased new
Why did I purchase a new Jeep rather than a used Jeep? At the time I was
interested in finding a Jeep I needed a daily driver that would not leave me stranded.
I drove a lot of used Jeeps because I thought I could only afford a used Jeep.
That is where I discovered the amazing resale value of Jeeps here in California.
All of the Jeeps I was looking at cost between $7,000 to $9,000. When I
looked at the dealer at new Wranglers, they were starting at $10,500. With interest
rates being lower on new vehicles as opposed to used vehicles, I bought a brand new 1993
Wrangler with the 4.0L engine for $14,500. If I had it all to do over again I would
now buy a older Jeep because I know that I'd be throwing away almost everything except the
body and frame. And I now have another vehicle for my daily driver.
Sony CD player and changer
control installed
I chose the Sony CD player/changer control for my Wrangler because it was the best stereo
I could find at the time. I felt I would most likely install a changer behind the
rear seat someday. Soon I learned that my priorities were not audio related.
Besides, how well would my changer handle 40" water crossings when the changer would
have been mounted about 30" off the ground?
Sony CD player Remote Control purchased
I get a lot of heat regarding this one. Why do you have a remote control for a
stereo that is at arms length away? The answer is simple to anyone who's owned a
Jeep. How often does a Jeep owner adjust the volume of his Jeep stereo while driving
around with the top down? The answer is, pretty much every time he slows down or
speeds up.
Realistic CB
installed, CB antenna on rear passenger bumperette
I needed a CB radio really bad. I went to the local Radio Shack and bought
everything I needed to get talking to my friends while on trips.
1" shackle lift installed
I installed a 1" shackle lift on my Wrangler mainly because I didn't have a lot of
money and I didn't know any better. It was a way to modify my Jeep while not
spending a lot of money
30 Tires & 8
steel rims installed
I purchased a set of 30" tires from a friend for $200. I sold my original
wheels and tires to a tire company for $200. Free upgrade except for the $100 for
15"x8" chrome wheels.
2.5
Lift installed
I installed the 2.5" lift because I needed a little clearance and I couldn't afford a
real lift. The Add-A-Leaf creates a really rough ride and I don't recommend
it unless it's a last resort.
Large flood lights on the
front bumper installed
Large lights? Hmm, I needed more light. Who doesn't like additional light?
31 Mickey Thompson Mud Tires
installed
The Mickey Thompson Baja Mud Tires provided good traction but they had several drawbacks.
They were noisy, caused Jeep wandering, noisy, wore out quickly and they were
noisy.
JKS sway bar disconnects installed
The sway bar disconnects were a great addition. They provided much needed
additional suspension flex. If I had it to do again I would make my own though.
Track-Arms
removed
I removed the rear track arm to provide additional wheel travel. It helped out a
lot. It does make the Jeep a tiny bit more "wandery" on the road though.
A sacrifice I did not mind making.
Cow Grille on the front bumper
installed
Because is was free, that's why! Actually, it did come in handy a few times to tie
climbing ropes to.
Engine
replaced under warranty
The engine was replaced by the dealer because the #1 rod broke and caused major problems.
The engine block had 5 inch diameter holes on both sides.
Canyon City Spare Tire Carrier
installed
With the added weight of a 31x10.5x15 spare tire, the tailgate was cracking. The
Canyon City Tire Carrier came with steel reinforcements to strengthen the back of the Jeep
body.
New front passengers
side fender painted and installed
Heh, funny story. Two unprepared Jeeps wander onto the Doran Canyon trail. End
result, many broken parts and a mashed fender on each Jeep.
Clinometer
mounted in the dash (Clinometer came from a Daihatsu Rocky)
Because it was free! Actually, I find it a nice addition to the dash board. It
mounts flush and is back-lit.
3
body lift installed
Because it was cheap. I needed a little extra clearance for the tires because they
were contacting the fenders on full compression. I figured I'd get my moneys worth
by buying the largest body lift I could find. This was before I learned that body
lifts are not really that desirable on a rock crawling Jeep.
Off-Your-Rocker rocker
protection installed
I found the need for rocker protection during the installation of the 3" body lift.
I didn't have any convenient place to jack up the body off of the frame.
Since then I've learned that there is no substitute for Off-Your-Rocker rocker
guards. All of the other companies make aluminum protection that would have crumpled
many times on my Jeep. The OYR guards have saved my hide many times.
4.10
gears installed in front and rear axles (original gear ratio 3.08)
I changed the gear ratios in the pumpkins for the same reason that everyone else does it.
Larger tires, wanna go slower while rock crawling, etc.... I chose 4.10 gears
because I never thought that I'd have larger tires than 31". I have since been
proven wrong and have had to re-regear.
Off-Your-Rocker corner
protection installed
I installed the corner protection for the same reason that most people do, I smashed a
corner panel and wanted to hide the damage and prevent future damage. The damage
under the drivers side corner guard really isn't that bad. But after seeing how easy
the body work folds when the Jeep is leaned up against a rock I decided to beef it up a
little. I have smacked those corner guards on rocks all over the place and they
still look brand new.
Less restricting muffler installed
I installed a different muffler because I wanted a less restricted exhaust system.
However, this muffler was not a quality product and I burnt it up in less than one
month. I wish that I could remember the name of this crappy product, but I don't.
I recommend using FlowMaster instead.
FlowMaster 2 chamber muffler
installed
This is when I installed a real muffler. The FlowMaster has never let me down.
It is welded right up next to the catalytic converter and still it performs
awesome.
I needed to install this muffler to replace a pathetic muffler I had installed
previously
CB antenna
re-located to the top of the spare tire carrier
The CB antenna needed to be relocated because I decided that I did not want to have
bumperetts anymore. The mount on top of the Canyon City Tire Carrier was simple.
Just drill one single hole and wire it up.
33 Mickey Thompson HP
tires installed
As everyone else out there feels, I wanted larger tires. I chose the Mickey Thompson
HP's because I liked the side tread and the 3-ply side wall. Unfortunately, I did
not know about the handling problems with the MT tires. You can read more about the
handling problems below.
Warn 9000I winch installed,
Cow Grille removed
After a year and a half of relying on Darrin to rescue me if, when I got
stuck I decided it was time to fork out the big bucks. I really didn't like the cow
grille that much anyways.
10 wide steel rims installed
I installed the 10" wide steel rims to combat the handling problems I was facing
from the Mickey Thompson tires. The MT tire company recommended that I run rims the
same width as the shoulder of the tire. The 10" rims did help quite a bit, but
I believe the root of the problem is that the 33" MT tires run at 20 pounds of air
pressure, normally!
Lock-Rite lockers
installed in the front and rear axles
I installed the Lock-Rite lockers in the front and rear axles because I needed some sort
of locker with all of the new trails that we were trying. The Lock-Rite locker
didn't last too long in the rear axle though because I couldn't stand the way it made my
Jeep handle on turns. I never drove on ice or snow with the rear Lock-Rite, but I
can imagine the carnage.
Barometric
Altimeter installed
I got the altimeter for the obvious reason, I wanted to watch the altitude changes while
driving the trails.
Lock-Rite
removed from rear axle, ARB installed in rear Dana 35C axle
I removed the Lock-Rite locker from the rear axle and installed an ARB because the
Lock-Rite locker is a poor choice for the rear axle of on-road vehicles. I was ready
for some adverse effects while driving on-road, but the adverse effects
were way too much for my short wheelbase Jeep. The ARB was an expensive choice, but
worth the money.
Rear
drive shaft modified to handle 1330-1310 conversion U-Joint
My Jeep was experiencing many rear drive shaft failures. 7 broken U-joints, 2 broken
yokes (into the pumpkin) and 1 broken slip-yoke (into the transfer case). I replaced
the input yoke into the pumpkin with a 1330 size yoke. I then used a conversion
U-joint between the 1310 drive shaft and the 1330 pumpkin yoke. This provided U-bolts
to hold the U-joint to the pumpkin yoke instead of those pathetic little
"straps" and bolts. This solution greatly lessened the drive shaft
failures, but did not eliminate them. The drive shaft failures were not eliminated
until the Spring Over Axle suspension project.
On-board
air system installed
I made an on-board air system so I could air up the tires faster and I could run air tools
effectively. The on-board air system includes a belt driven compressor (purchased
from a friend for $40), a 2.5 gal "hotdog" air tank (purchased from Grainger for
$60), a 1/2" check valve, 20 feet of 1/2" hose and an in-dash air pressure gauge
(back-lit). I used the air pressure switch provided with the ARB compressor.
Grant
steering wheel installed
I like the Grant steering wheel because the grip is larger than a stock steering wheel.
The diameter is just a wee bit smaller to give me more leg room. Also, the
wheel is telescoped back a bit more which seems to fit me a lot better.
Spare
Tire rack modified to carry one metal can and one plastic can
The Canyon City tire carrier comes equipped to carry two 5 gal metal Jerry cans.
I wanted to carry 5 gallons of fuel and 5 gallons of water. Well, metal Jerry
cans do not carry water very well. Can you say "5 gallons of rust"?
I only changed one of the mounts to accommodate a plastic container because I was still
looking for a blue plastic container shaped the same as my red plastic container. I never did find one. :(
Bestop 2-pane upper
door halves installed - From ACME
I chose to buy the Bestop glass upper door halves because the plastic windows are
difficult to see through at certain times. Also, the zippers on the stock upper door
halves are difficult to keep clean. When the dirt/dust builds up a little, the
zippers become jammed and sometimes dislocate. The glass windows have there good
points and there bad points. Good = easy to clean, easy to see through Bad =
the tracks collect dirt and small rocks, I can only have one end of window opening open at
one time, glass shatters when it is bent (learned first hand).
Large flood
lights removed and smaller flood lights installed
I wanted to chop the bumper ends off so I needed to mount smaller lights closer to the
winch
Chopped front bumper
to be the same width as the frame
I chopped the front bumper down because I was tired of the bumper coming in contact with
rocks while wheel'n. More than one person told me that now that the bumper is
chopped down, I'll hit the fender on the rocks instead. I can tell you first hand that this
is not true. The fender is quite a bit higher then
the bumper ends were.
Spring Over Axle suspension
implemented
OK, this is the largest project I've implemented on my Wrangler so far. I researched many
suspension kits/products/ideas out on the market. I did not like any of them.
Each had there own good points, but I wanted a complete suspension system that did not
have any drawbacks. I wanted to implement a shackle reversal system while lifting my
Jeep. The problem with most shackle reversal kits is that they have this tower that
hangs down from the front bumper that limits your approach angle. None of the kits
would raise the spring hanger because that would greatly effect the caster angle on the
front axle. Since I was planning on relocating the spring hangers for the Spring
Over Axle setup anyway, I had no problem in rotating the caster angle back to where it
belongs. Next, I wanted to move the front axle forward at least 1" so when the tire
compresses, it will not come in contact with the fender. The JKS sway bars
disconnects needed to be shortened because the U-bolt plate was relocated above the axle
making the distance to the sway bar much shorter than stock. The U-bolt plates
needed to be modified to provide a smooth surface for the bump stops to come in contact
with. The front track arm needed to be added to combat "Bumpsteer".
The angle and mounting locations for this bar are critical to creating a geometrically
correct suspension systems. I modified the front passenger side U-bolt plate to
mount the track arm to. I installed the MIT NP231 transfer case shortening
kit to
lengthen the rear drive shaft. This kit is expensive and the directions are
incomplete, but when it was all over the kit worked great. Since the rear drive shaft
was lengthened I was able to remove the hardware that lowered the transfer case. I
also removed the 3" body lift because it was no longer needed. I then installed
Rancho RS9000 shocks on all for corners and installed the dual in-dash control.
Finally I was able to take measurements for drive shaft modifications. The front
drive shaft only needed to be lengthened. The rear drive shaft is another story.
It turned out to be a full 6" longer than stock, needed a CV universal at the
transfer case end, a standard slip joint in the middle and a full 1330 universal at the
pumpkin end. I have had not one single rear drive shaft problem since this upgrade
(knock on wood). I have developed a bit of spring wrap from the SOA setup. I
have tried a few different configurations to combat this but I have not found one that
will eliminate the wrap and not limit suspension travel. Someday I'll come up with
something. Besides, the spring wrap really isn't that bad right now with the stock
engine. When I upgrade to a larger engine I'll have to do something about the
wrap for sure. Overall the suspension project turned out to be a great success and I am
very happy with it.
Windshield
replaced
Why was the windshield replaced? Because it was cracked. No, the crack was not
related to any four wheel drive trip gone bad.
Hi-Lift Jack mounted on the winch
plate
First I searched all over my Jeep for a good place to mount the Hi-Lift Jack to. I
couldn't find any place better then the winch plate. I used the standard Hi-Lift
Jack mounting plates provided by Conn-Ferr. I cut them down quite a bit and welded
them to my winch plate standing straight up. This holds the Hi-Lift Jack above the
roller fairlead for the winch.
Full roll
cage installed - Integrated CB mount and dome lights
I installed the full roll cage for added protection if I were to roll. I also wanted
a place to mount a CB and a dome light. This setup has worked out really good.
Currie
Rock Crawler rear bumper installed, welded on U-Bolts for chain attachments
I chose the Currie "Rock Crawler" rear bumper mainly because it was on sale.
I was going to fabricate my own, but this one was way too cheap to pass up. I
bought it after Currie released there "Rock Crawler II" bumper. The
release of the II bumper drove the price way down on my bumper. This bumper has an
integrated 2" receiver box but did not come with any place to attach a chain when
towing a trailer. I cut down and welded on a couple of old U-bolts that were used to
hold the rear axle to the leaf springs.
Rear
2 springs re-arranged with the second leaf replaced with original second leaf
(lowered rear a little)
The rear suspension on my Wrangler sat just a bit too high. Apparently I needed a
1" lifted spring to make the Jeep sit level. I took apart the spring packs and
exchanged the second longest leaf for my original second longest leaf. This made the
Jeep sit perfectly level.
Alternator
rebuilt 90Amp
During my trip to Surprise Canyon (major winching) my alternator decided to give out.
After getting home I was faced with the decision to either rebuild my alternator or
purchase an under-hood welding system. Well, budgets constraints got the best of
me
and I had my 75Amp alternator rebuilt to 90Amp. Someday I'll break down and get that
darn under-hood welder.
RS5000 Steering Stabilizer installed
I replace my steering stabilizer with a Rancho RS5000 unit because the original steering
stabilizer started leaking fluid
33" Goodyear
Wrangler Mud Terrain tires installed
After years of putting up with the Mickey Thompson tires causing my Jeep to wander in my
lane while driving on the highway I decided to trade up. I got the Goodyear's
because
I liked the tread pattern and I had heard good reviews about them. I was very happy
with them for quite a while. The downfall of the Goodyear's ended up being the thin
sidewall. The sidewall is not necessarily "thin" but it is not heavy
duty.
Clutch master
and slave cylinders for 1991 Wrangler installed
I changed the Clutch master and slave cylinders because I did not like the hydraulic
line
between them. The line started leaking at the joint with the slave cylinder and
never stopped. I couldn't change the line itself without changing the
slave cylinder. I
decided that I would never be placed in that situation again. It took a little
modification on the firewall (because the master cylinder for a '91 Wrangler does not
mount in the same position as for the '93 Wrangler) but I managed to purge my Jeep of that
pathetically engineered product. Next time I have any clutch problems, I'll be
installing a bell housing, slave cylinder, and fork from a '95 or newer Wrangler. The new
Wranglers no longer use the throw-out bearing/slave cylinder thingy. The new
Wranglers have gone back to external slave cylinders. Good old fashioned engineering.
RCI
2950 10-meter radio installed, used as a CB. New antenna installed on spare tire carrier
I chose the RCI 2950 10-meter radio because of it's internal power. This radio can
communicate in the CB frequency range and yet has 10 watts of internal power. I also
installed a new antenna in the same place on the spare tire carrier to go along with the
new radio
Splitfire plugs and wires installed
I chose Splitfire plugs and wires simply because they are the best available.
Hand fab'd roof rack,
mounts directly to roll cage
I built my own roof rack because (as usual) I did not like any other product available.
This rack bolts directly to the roll cage, hence, must be removed when the soft top
is installed (rarely). I did, however, make this roof rack hinge in the middle and
can be folded in half to fit inside the Jeep behind the rear seat. Overall I'd say
this rack has great potential, but does has it's limitations. Small, heavy,
inconvenient in the rain, etc...
Spare
tire carrier modified
I modified the Canyon City spare tire carrier again. I wanted to carry two 5 gal
plastic gas cans instead of one metal and one plastic. Also I modified the lower
support arm to place pressure on the rear bumper instead of the tailgate. Canyon
City's design has a bar that pushes on the tailgate to help steady the bouncing effect
that can happen when driving down the highway. When I was carrying 10 gallons of
fluid and a 33" tire the entire assembly would hop. This
bar also was slowly pushing a dent into the tailgate, something I'd rather avoid if I can.
My design was to push down diagonally on the rear bumper. This way I could
place more weight on that extra bar (since it won't dent the bumper) and that would in
turn help to eliminate the bouncing effect on the highway. Complete success!
Created
new front bumper from Travis old stock bumper, cap'd ends, welded light tabs
Again, I was (still am) unhappy with the available products for the front bumper on my
Wrangler. I decided to make my own. I started with a straight, full length CJ
front bumper and started hacking away. I cut it down to the same width as my frame.
I drilled new mounting holes since the widths of the CJ's and the YJ's are
different. I welded on triangle caps to the ends to give it that finished look.
I also welded on two tabs to mount my fog lights to in front of the winch. In
the future I do plan on building another front bumper because I'd like to incorporate a
front 2" receiver box.
Currie 2" receiver hook
installed
I installed the Currie 2" receiver hook because it was cheap and very useful.
Attaching the loop end of a tow strap to my receiver use to consist of removing the hitch
pin, cramming the strap in the 2" receiver box and then trying to shove the hitch pin
trough the loop. The Currie hook is a great alternative to that.
Hand
fabd rear cross-member to mount shocks to, new rear RS 9000 shocks (much longer)
The location of the rear upper shock mounts caused the suspension to be limited. The
factory's solution to this problem on most vehicles is to lower the lower mount (located
on the axle on solid axle vehicles) well below the axle itself. I did not like that
solution because I wanted to increase my clearance. I chose to move the upper mounts
instead. I welded in a piece of 4" x 3" x 1/4" angle iron as a frame
cross member. I mounted the shocks toward the center of this cross member for two
reasons. 1. increased rear axle travel through the use of longer shocks. 2.
With the shocks leaning at a 45 degree angle the rear suspension is
"softened". The lower shock mounts were also fabricated from scrap
material. I used 1/8" thick stock and bent a 1.5" wide section into a
square "U" shape. This "U" shape was then welded to the axle at
it's center point (i.e. nothing hangs below the axle tube). I then bolted the shock
to this "U" with the Rancho shock hanging bolt thingy's. It's really hard
to explain so I'll place some pictures here in the future. (side note: I
replaced this with a new shock cross member, so no pictures are forthcoming of
the old design ;) The new design can be found on this
page)
New rear
axle - Dana 44, reverse cut, 4.56 gears, ARB, disk brakes
I replaced my stock Dana 35C axle with a Dana 44 reverse cut axle because I bent the Dana
35C axle on a 4-wheel trip to Calico, CA. I hit a couple of whopp-dee-doo's a little
too fast and all hell broke loose. The axle was still drivable, but it was
definitely bent. I chose the Dana 44 Reverse cut for a couple of reasons. 1.
I needed a beefier axle so I would be less likely to bend it again. 2.
I needed a reverse cut axle to help eliminate driveline angles. I chose the 44 over
the 60 because the 60 was about twice the cost! I could get a standard rotation 60
for the same price as the reverse 44, but then I would definitely have driveline
problems. I ordered my 44 with 4.56 gears (which meant that re-re-gearing the front
axle was needed), an ARB and disk brakes. I had an ARB in my Dana 35C so it was
nothing new to me. The disk brakes however, where new to me and I think is a great
upgrade. My braking control while backing down something is greatly increased.
Driving down the highway I really don't notice any differences with the
rear disk brakes
though. I'll be upgrading my brake master cylinder and proportioning valve someday
and I expect better on-road and off-road braking then.
Recalibrate
speedometer
I've recalibrated the speedometer several times with all of the tire and gear changes.
This time it was recalibrated because I was in the process of changing from 4.10
gears to 4.56 gears.
4.56
gears installed in front axle
I needed to change the gears in the front axle from 4.10 to 4.56 because I ordered the
rear axle with 4.56 gears.
Exhaust
system rerouted to clear the axle which now has more up travel
With the new frame cross member and the new Dana 44 rear axle, I needed to reroute the
exhaust. I have my exhaust done at a local shop because I don't have the tools to
bend the pipe. Unfortunately, I'm not happy with the quality of the work this time
around, which is why I don't mention the shop's name. Not only is there a problem in
quality, but I got a lot of attitude because I was "picky" about what I wanted
done. Last time I checked it was my Jeep he was working on and it's my money the he
is getting paid with. I'll be thinking pretty hard before I bring the Jeep back
there next time my exhaust needs rerouting.
Flex fan installed
I installed the flex fan in hopes of getting a little better performance at highway
speeds. A flex fan came recommended by a friend who had been running one and was
happy with it. Also, I've learned that when crossing deep water, a flex fan will
splash less water than a factory fan. Someday I do intend to convert to an electric
fan instead.
35"
BFG Mud Terrain tires installed
Here I go again, larger tires. I've said it before and I'll say it again.
"I don't think that I'll ever want/need tires larger than __". Fill in the
blank with the latest tire size, 35". I changed to BFG Mud Terrain's because I
like the tread pattern and the 3-ply sidewall. While driving the Dusy/Ershim trail I
cut a sidewall on my Goodyear tires. That is unacceptable! Well, maybe not
unacceptable. But with a stronger sidewall I can certainly waiver the odds more in my
favor. So far (knock on wood again) I haven't cut the sidewall of my BFG's.
(side note: never did cut a BFG side wall)
1.5"
body lift installed, cut the original 3" body lift in half
Well, with the new 35" tires I guess it can be expected to have a little fender
rubbing. I chose to body lift 1.5" because I had my old 3" body lift
blocks lying there and I felt like cutting them in half. Then I ran to True Value
Hardware and picked out a set of new bolts. My preference is to have no body lift,
but I'd rather body lift than limit suspension compression.
35" BFG Mud
Terrain tire installed for the spare tire
I think it is important to have a spare tire the same diameter as the tires on the ground
so if you get a flat, install the spare and need to run with your lockers locked you don't
have to drive in a circle. :) I ran with a 33" spare for a while because I was
looking for a used 35" tire for a spare. Well, shucks I couldn't find one.
So instead I bought another 35" BFG and mounted it up.
4-1 gear
reduction and 2-lo installed in the transfer case
Wahoo, I like this upgrade. First lets talk about the 2-lo kit. This kit makes
it possible to put the transfer case in 2 wheel drive low range. This is useful when
you're trying to make a sharp corner while crawling along in low range. I can shift
on the fly to 2-lo, go around the corner and shift on the fly back into 4-lo. Very
cool! Next, anyone who 4-wheel's "rock crawling" style knows the
benefits to lower gear ratios. Those of you who don't know, it works like this. The
slower you go, the farther you go, the less parts you break, the more time you have to
examine the best line, the more fun you (I) have, blah, blah, blah... My crawl ratio
went from 48:1 to 70:1 with the 4-1 kit. Want
to figure out your gear ratio?
Installed
a factory hard top and factory full metal doors
I was originally looking for a factory hard top and doors but found the
prices (used) to be unreasonable. A friend then bought a Jeep and he didn't want
the hard top. He was looking for a soft top Jeep but came across this hard
top Jeep and bought it. He sold me the hard top and full metal doors for
real cheap. The hard top was gray and the doors were red. I had the
hard top painted black and had the doors painted Chrysler white to match my
jeep. With the full roll cage installed I couldn't roll the windows down
with the doors shut, so I installed a power window kit from Summit Racing.
I mounted the switches on my center council down in front of the cup
holders. I had to change my full roll cage to accommodate the hard
top. I had four bent bars going from the main hoop to the front
hoop. These were too high and held the hard top up off the Jeep. I
removed the roll cage, cut out the bent bars and welded in straight bars.
I also had the windows tinted to help keep things cool inside.
Purchased and Modified a
1967
M416 trailer
I thought a trailer might come in handy on those trips where there's more people
than Natalie and I in our Jeep. I like the sturdy construction and low
price of these old military trailers. Project
page.
Installed
a Mobi-Weld, dual Odyssey batteries and a custom dual battery tray
I've always wanted a under hood welder and I found that Mobi-Weld is the best
one on the market. Same thing with the Odyssey batteries. I couldn't
find a dual battery tray out there that I liked, so I made my own.
Changed
all air hoses to Teflon lined / Steel Braided hoses
I never liked the "hardware store" hoses because when I sat still
for a while (airing up tires on 6 Jeeps) the hoses in the engine compartment
would get hot and blow off the barbs. I had the hoses remade at "Top
Line" in Temecula. These new hoses are 1/2" ID, Teflon lined,
Steel Braided and have 3000lb pressure "spinning" ends. No more
blowing hoses!
Custom
"ladder bars" made and installed
I modified my u-bolt plates for the rear axle with a plate that extends up
about 6 inches. At the end of this plate is a 3/4" bolt that mounts a
single bar with Heim joints on the end. The "ladder bar" extends
forward to the outside of the frame above the forward eye bolt on the leaf
spring. I triangulated the axle position relative to the frame with the
wheel completely compressed and with it completely drooped. I used this
data to triangulate the most effective position to mount the forward end of the
ladder bar. This way when the wheels are completely compressed or
completely drooped there is no suspension bind and my wheel travel is not
limited. To make room for the ladder bar mount I had to cut off the
factory body mounts and fabricate my own, 1 1/2" higher then normal.
I guess the body lift is permanent now.
Dana 44 front
axle
While wheeling in Los Coyotes, my stock Dana 30 axle finally gave out.
I decided that the axle was not worth repairing so I ordered a Dana 44 from Tri
County Gear. I ordered the axle custom for my spring over and reverse
shackle setup. I got 4.88 gears, an ARB locker, Warn hubs and Tri County's
"High Steer" knuckles. This allowed my drag link to be nearly parallel
with the connecting arm eliminating bump steer and the need for a track arm.
Regeared
and re-lugged the rear Dana 44 reverse cut axle
I ordered my front axle with a 4.88 gear ratio so I had to change the rear
axle from 4.56 to 4.88 to match. Also, since the "High Steer"
knuckles are only available with a 5x5.5" lug pattern I had the rear axle
lug pattern converted to this size.
American
Racing wheels with Champion Bead Locks
I had to change my wheels because of the new Dana 44 front axle. The
"High Steer" knuckles are only available with the CJ bolt pattern lugs
(5x5.5"). I figured while I was changing the wheels I might as well
go for bead locks as well. I sent the American Racing Baja
15"x10" wheels to Champion in Fresno and had bead locks installed.
I also had to modify my swing away tire carrier to hold a wheel with a
5x5.5" lug pattern.
35"x12.5"x15"
Super Swamper SSR's
I've seen these tires around quite a bit lately and thought I'd give them a
shot. Eric has run them on his Jeep for a while now and is happy with
them.
Storage
boxes on the fender wells
I found 23" long storage boxes at Ace Hardware. They are actually
tool boxes but fit perfectly on the fender wells of my Jeep to store all the
junk that goes along with a Jeep. Tow straps, winch control, extra parts,
etc. I installed footman loops at each end of each box to hold the box
down and to hold the lid shut.
Fabricated a Fender Rack
I made a rack out of 1 inch square tubing. The front is mounted on a hinge
and bolted to the front of the rear fenders inside the Jeep. There's a
latch in the back to hold it down. I had the rack powder coated for more
durability. When this rack is installed, I stuff my sleeping bags, clothes
bags, Therma-Rests and tools under the rack. On top, I strap down the
cooler and dry food box. This way we can get to the cooler during the day
on the trail without having to dig under sleeping bags and clothes bags.
Installed
rear Revolver shackles
I've always wanted to give these a try and a price reduction convinced me.
I can't use them in the front yet because I haven't made my front shock hoops
yet. Therefore the shocks are too short and the Revolvers wouldn't ever
open. In the back though, it's a different story.

Fabricated a front receiver
hitch
I'm tired of maneuvering my trailers around the house by having to
backup. With a receiver hitch in the front of my Jeep, I can push these
trailers around more easily. Project
page..
Fabricated
a 6-switch electrical panel
I made a panel to hold 6 electrical switches. The switches are for Front
ARB, Rear ARB, Compressor, Front Lights, Side Lights and Rear Lights. The
Front Lights and Rear Lights are 3-position switches. The functions are ON
/ OFF / ON when in reverse or when the brights are on. I have pictures of
the wiring on the back of
the panel, and of the panel in the dash.
I also installed new (smaller) lights on the front bumper and on the spare tire
carrier. This switch panel mounts where I had my in-dash clinometer
mounted. I never really used the gauge that much anyway, so in the trash
it went.
Reconfigured
leaf springs
The springs on my Jeep (2" Skyjackers) have settled over the years and my
Jeep was sitting lower and the rear springs were wrapping more and more. A
friend returned the 2" Add-A-Leafs he was borrowing, so I thought I'd give
them a try. I replaced the 2nd leaf in the rear packs with the
Add-a-Leafs. Then I took those 2nd leafs from the rear sets and installed
them in the front packs. This netted about 1 1/2" of lift all
around. Also, it stiffened up the ride a little which I needed.
Spring wrap seems nearly gone. Also, on the
trail I discovered I'm not nearly as top heavy, or at least I don't feel top
heavy.
Supported
grille sides
Finally I made my grille supports that I was supposed to install with my body
lift. The front clip had dropped 1/2" and was obvious in the hinge
gap between the hood and cowl. I used to scrap material I had in my metal
drawer and welded them in place.
Flat
skid plate, 3" raised body mounts, gas tank and engine lifted 3", new
shock cross member, air tank relocated
I wanted the skid plate to be completely flat. To do that I needed to lift
the body more than the current 1.5" body lift and I had to move the engine up
3". Moving the engine up 3" meant I had to make a new York compressor
mount so the compressor wouldn't hit the hood. While I was remaking all
the body mounts, I had the opportunity to move the gas tank up 3" as well.
The 3" body lift also gave me room to move the rear shock cross member up a bit
as well. I recently hit the air tank on some rocks, so I relocated it to a
new mount on the new shock cross member.
Project page.
Upgraded
air system from 90# to 125#
The primary reason I changed the pressure switch to a 125# one was because the
trailer air brakes were slightly lacking. I wanted more pressure. A
side benefit is more powerful air tools on the trail.
38.5"
x 14.5" x 15" Super Swamper TSL/SX tires
A friend was looking to buy some 35" SSR tires, so I took advantage of the
situation to go to larger tires. The recent suspension work, and increased
"body lift" made my 35" SSR's look small. Also, I had a
little extra space above the Jeep to the garage so I could fit a larger
tire. I originally looked at the 37"x13"x15" Boggers, but I
really don't like the horizontal lugs all the way across. I'm sure they're
fantastic in the mud, but I don't see a lot of mud. The SX looked like a
much better choice for me. Going to 38.5" really pushed the limits of
fitting in the garage with the hard top on. I have to enter real slow
because I do rub the rubber molding for the sectional garage door. No
damage if I stay real slow. 9 months out of the year the hard top sits on
the side of the house and I'll fit just fine then. I decided to go with
the 14.5" width just to keep the tire proportional. I'll still fit on
the trailer, but just barely. On the 15"x10" wheel, the tire is
a little "ballooned" but I think it's acceptable. As soon as the
digital camera gets back from Nikon I'll post a couple pictures.
AGR RockRam steering assist
I thought the new, larger tires might make steering a little more
difficult. I picked up this AGR RockRam system from a friend for a really
great price. It includes the AGR Super Pump, steering box and of course
the ram.
3/16" Rocker Panels
I originally had Off-Your-Rocker rocker guards on my Jeep. They worked
great for several years. Recently, I hit the side of the Jeep on a rock on
the Sledge Hammer trail just above the guard itself. Since the the OYR
guards were only 4" tall and there was room for 6" of material, I
decided to make my own. Another problem I had with the OYR guards is that
they provided no lateral support. I twisted the passenger side rocker
pretty good in the "Big Sluice" on Rubicon a few years ago and it's
never been the same. My new guards run all the way to the center body
mount underneath. This provides a TON of lateral support. I also
made these out of 3/16" material which is about twice as thick as the
OYR's. The break up the tall look of the side of the guard, I added
1.25" diameter, .25" wall tubing.
Front Shock Hoops
The stock front shock hoops just weren't cutting it. Especially with a
3" body relocation. I made the new ones out of 1.25" diameter,
.25" wall tubing. I also had to change the shocks out for longer
ones, Rancho 9000 9012's.
Swing Away Tire Carrier
The old tire carrier hung on the body. I developed some cracks, but
they weren't getting any worse. The problem was the tire hanging so far
behind the Jeep. The gas cans were between the tire and the
tailgate. The tire weighs A LOT more than the gas cans, so it made sense
that the tire be close to the Jeep and the cans hang behind it. I built
the new bumper out of .25" wall 2"x4" box tubing. I welded
bolts inside the bumper for mounting to the stock holes in the back of the
frame. I also welded in a Swing Away hinge that is actually a trailer axle
stub. Next, I welded on more supports on the back of my permanent body
lift. The tire swing itself is made from 1.5" x 3" x 3/16"
wall tubing. I made a separate attachment for the tire that can be flipped
upside-down that will lower the tire 7.5" for more visibility when
desired. In the center of the tire is a standard 2" receiver for
mounting accessories. I made a gas can holder for it already. The
latch to hold the swing shut is a triple lock system that can be operated with
one hand. I haven't seen a swing away out on the market with an easier to
use latch, yet extremely secure.
Front frame work,
steering box relocation
I wanted to move my steering box so I could move the axle forward. This
required making major changes the front of the frame.

Rebuilt the roll cage
I was getting tired of the roll cage I've had installed for all these
years. It's your typical Smittybuilt setup with a hoop from the drivers
side floor, to the passenger side floor. I decided to try something a
little more creative this time around.

CTM's
and Warn Chrome Nickel Alloy Axles
I keep wearing out axle shafts so quickly that it just makes more sense to spend
the money up front and take care of the problem.
Project page.
Changed out the rear axle to a
ProRock60 / Rear 4-link and Fox coil-overs
While out at Johnson Valley, I met a guy that works for Dynatrac. He's
getting me a great deal on a ProRock 60 axle that I can't pass up. I've
been thinking about having a Ford 9" built at Currie, but it just doesn't
make sense when for less money I can have a ProRock 60. At the same time,
I don't really want to setup this axle with leaf springs. Might as well go
for the 4-link and coil setup I've always thought about.
Project page.
LED tail lights
While at Johnson Valley, I smacked my passenger side tail light on a rock and
broke it. Not bad for a 10 year old Jeep. These were the factory
tail lights.

Sold
the hardtop and full doors
I wasn't planning on selling them, but since I only had them installed for 2
days the entire winter, and the fact that my roll cage is just a little too
big, I figured "why not"? A guy posted on JeepAholics.com
that his friend was looking for a top and doors, so I said
"OK". Funny, I bought the top and doors from a friend of mine
who bought a Red '91 YJ. The hardtop was grey and of course the doors
were red. I painted the top black, and the doors white. Well, the
guy that just bought the top and doors has a red '91 YJ. :)
New
cross member, reworked lower links
The skid plate was taking a beating from the lower links. They just
couldn't handle the stress.
Project
page.
Cutting
brakes, adjustable proportioning valve
I've always wanted to have cutting brakes on my Jeep. Since I had to
rework the lower links, I had to make new brakes lines anyways.
Figured this is the best time to rip out the stock proportioning valve,
install an adjustable prop valve and install some cutting brake levers.
Project
page.
E350 Brake
Master Cylinder
Heard about this swap on the net and figured I'd give it a try. With a
little coaxing, the master cylinder bolted right up and provides a little more
braking power. Nothing earth-shattering, but better than the stock
10year old MC.
Project
page.
Rev1 front
fenders
Rev1 called me up and asked me to field test their new fenders. RVMD was
nice enough to paint them up for me. My stock fenders have been taking a
beating the past few months and couldn't stand up to the abuse. The new
fenders are very strong and should hold up just fine.

Removed stereo, CB & dual in-dash controller for the Rancho 9000's
Seems I never use the Alpine stereo anymore. I've never liked having the
radio on while on the trail, and that's the only place I'm driving the Jeep
anymore. I had to remove the front speakers for the roll cage to pass
through the dash, and the rear speakers were always in the way. With no
speakers, the stereo wasn't much more than a clock. I also removed the
Cobra CB because it's so large. Anytime someone would ride in the
passenger seat, they had to be careful not to bang their knee on the corner of
the CB. Instead, I mounted a much smaller, cheap Radio Shack CB in the
hole where the stereo was. Lastly, I also removed the dual in dash
controller for the Rancho 9000 shocks. Since installing the coil-overs in
the back, the controller only changed the front shocks. And since I only
ever drive the Jeep on the trail anymore, it was always adjusted to "5"
(stiffest setting). Instead of having to bump up the controller several
times a day to maintain that setting, I decided I would just re-install the
knobs on the shocks and twist them to that setting and leave them there.
Disconnect
steering wheel
After having the cutting brake levers next to my seat for a few months now, I
realized just how much they were in the way. When it comes to using the
levers, they're in the perfect spot, but for getting in and out of the Jeep
they're not. By disconnecting the steering wheel and getting it out of the
way, I can get in and out easily.
Project page.
Atlas
II 5.0:1 transfer case
I've been wanting to switch to an Atlas for years now. It's always been an
upgrade that was easily postponed since there's been other things more
important. Since the trails we've been running are getting harder and
harder, I knew that someday I'm going to blow up the aluminum NP231. It's
better to remove it and sell it while it's still worth something. The new
case has even lower gears (4:1 in the NP231 and 5:1 in the Atlas) which slow me
down a bit. I was at about 75:1 and now I'll be at 93:1. Also the
new case give me a twin stick control and allows front only drive in low range.
That combined with my cutting breaks should give me some great options.
Project page.
Replaced the
winch cable
Back in June I broke my winch cable while using it for steering. The
steering box had broken off the frame, so I routed the cable through a pulley
and to the tie rod. Worked great, but I had to go 5 miles. About 3
miles into the trek, the cable broken because it was rubbing the bottom of the
frame. I tied it in a knot and kept on going. I searched web forums
for someone with a used cable for sale, but couldn't find one. I bought a
new one from Warn.
Changed out the 9000i
winch for the 9.5xp winch
One friend of mine was looking to sell a new 9.5xp winch, and another friend was
looking for a deal on a winch. I sold my 9000i winch and bought the 9.5xp
winch. The 9.5 has about doubled the line speed as the 9000i, so that will
be nice. Since I replaced the winch cable on the 9000i within the last 70
miles on the odometer, the buyer is getting a great deal.
Tires
Came time to replace the tires. I already had one brand new tire that was
my spare, so I bought three more and rotated one of the old ones to be the
spare. I stuck with the same brand and size, 38.5" x 14.5" x 15" Super
Swamper TSL/SX.
Battery
I had to replace one of my batteries. The primary battery wouldn't engage
the relay that connects the two batteries (a week ago). I checked the
voltage and it was at 5v. I put the charger on it for a couple days and it
only got up to 7v. A few days after that it was back down to 5v again.
I got a pretty good life out of the old one, 7 years. Odyssey changed
their battery colors, so the new one is red. I didn't bother changing the
2nd battery since it still reads 13v.
Hydrostatic
Steering
Last year, at Dinkey Creek, I broke my AGR steering box. The field fix
solution was to buy a stock steering box from a scrap yard. All we could
find was a '88 Jeep Waggoner, so I bought that box. It steered the wheels,
but sucked. At a stop the steering was weak. At speed it was super
powerful, basically the opposite you're looking for in a steering box.
Over the last few months, the pump was been whining and the steering power was
getting weaker and weaker. I had a decision to make. Either drop
more cash into a stock steering setup that never worked all that great with
38.5" tires at 5psi, or upgrade to a "full hydro" or hydrostatic steering setup.
I went the cheap and easy route with an 8" stroke, 2" diameter push-pull (single
ended) piston. I kept the 1" solid bar tie-rod that I have been running
all along on this front axle. I mounted the Orbitrol down on the frame
near where the steering box use to be. It's a bit further back, and higher
so it shouldn't interfere with anything. Basically, it's directly under
the radiator. It was a lot of work to get the air bubbles out, but now
that they are (as far as I can tell) the steering is great. The stock
steering box gave me about 3.75 turns lock-to-lock. This setup is about
1.75 turns, so it's very quick. It's a little touchy at 50MPH, but I don't
drive that fast very often. Most of the time when it's going that fast,
it's on a trailer :)
Hydrostatic Steering, round 2
I went to a balanced steering system because the unbalanced system was
annoying. More details on the
project page.
I also built a new dash with new gauges, which is why the mileage reset to 0.
Paint
It was finally time to give the Jeep a new look. Check out the
project page.
Dash board
With the Jeep taken apart for paint, I didn't want to throw the same 'ol dash
back in. Check out the
project page.
Roll cage
I had to cut the a-pillars on the old cage to get it out for the paint project.
Instead of patching the old bent cage together, I figured I'd bend up a new cage
with a new look. Check out the
project page.
Front shocks
When I took the old front shocks off to paint them I discovered the driver's
side shock was blown out. They had quite a few hard miles on them, so I
replaced them with Bilstein 5100 series shocks. Check out the
project page.
Drivers side outer axle
shaft replacement
I was driving in the front yard with some friends and
broke the driver's side outer axle shaft. It managed to take out the
spindle as well. This was a lifetime warranty WARN chrome alloy axle, but
I've been running it for 10 years or so. I figured I got my monies worth
out of it. Also, it wasn't under much stress when it let go, so I figured
I must have cracked it some time in the past, it just happened to let go today,
in the front yard :) While I had things apart I decided to rebuild the CTM
joints as well. I haven't greased them as often as I should have and they
were getting wobbly.
Replaced catalytic converter
The catalytic converter was rattling with its
innards falling apart. I welded in a new unit. While I was under
there I discovered a crack in my transmission cross member. The mounting
plate to the transmission had a cracked gusset. I welded the snot
out of it. I also FINALLY sleeved the frame where the forward skid plate
bolts pass through. 18ish years ago a friend convinced me that it didn't
need to be sleeved even though I knew better. Nice to have that the way I
want it.
New tires - 40x16x15 Super Swamper TSL LTB
I've had 38.5"x14.5"x15" tires
for the past 16 years. 4 years on the first set and 12 years on the
second. I decided to try something different and go just a bit larger.
Even though the LTB's are listed as 16" wide, they are only 15" wide on 10" wide
wheels. That's the same width as my 38.5" tires were.
Rebuilt
transmission mount without rubber insulator
The rubber in the
transmission mount wore out for the second time and caused the drive train to
move WAY too much. I made a new mount without any rubber at the
transmission. There is rubber where the mount connects to the frame (leaf
spring bushings).
Tied the front
shock hoops to the fenders
The front clip of the Jeep was
shaking all over the place. The shaking was enough that when the front end
because weightless (bouncing through snow) the steering shaft would disconnect
from the steering box. By tying the top of the shock hoops to the inner
fender wells. this keeps the front clip in the same location as the frame.
I also added a large washer to the bottom grill mount to keep that connection
solid.
