Here is the Jeep still stock |
Like the subject says:
I did the SOA on my ‘88 YJ 258. I won’t give the instructions, but I’ll try to
describe the problems I’ve encountered, questions I had, and maybe give some
advice for future SOA installations. I’ll also give you the story of getting home.
I have to warn you: don’t ever drive a Jeep like I did to get home. First, it
is time to thank some people. Special thanks go out to Lars Soo and Jim Bailey,
which helped me to get the Rubicon Express SOA kit in The Netherlands.
Furthermore I want to thank Craig Myers, Alan Wicker, Mike Garner, Dion Davis,
Louie Belt and Jefe Reynolds for their technical advice.
Before we (the
Spring-over team: Wim "the man next door" van de Pol, Gilbert
"eight-ball" Arensdorff, Mari "my uncle" Vekuijlen and
myself) did the installation, we hang the Jeep with some straps on tackles.
Danny "the lowrider" Drube couldn’t make it, but was mentally with
us. Then we hoist up the Jeep, so we could walk under it. The first problem
that I encountered was removing the pitman arm. I couldn’t get it off the drag
link AND the steering box. I tried it with my cheap pitman arm puller and an
expensive puller from somebody else, but it wouldn’t get off the steering box
(it got off the drag link after a half-hour). Wim decided not to spend more
time on it and cut it with a grinding-machine. Finally the pitman arm got off.
I had the luck that I could use all the tools that you can imagine. Especially
the airtools were handy.

The next important step
was welding the perches. I could lay hands on a cheap angle finder to measure
the angles. After welding the rear perches, the angle finder fell in pieces. I
measured the perches on the front axle with measuring tape. I could only lower
the front axle by removing my exhaust pipes (I don’t have a stock exhaust
system). When we tried to disconnect the rear brake-line from its mounting
location, the steel brake line broke. Wim tried to repair it by cutting a small
piece off it and re-routing the brake-line. When we tried to bleed the brakes,
we found out that it didn’t work, because it was leaking brake-oil. Mounting
the new shocks seemed very easy, but wasn’t so easy. We started with the rear
shock at the passenger side. We had a lot of troubles with the top bolt. When
we finally installed it on the top, we noticed that it wouldn’t fit at the
bottom mounting location. The axle hit the thick part of the shock. We decided
to install it upside down.

After installing the
drag link to the drop pitman arm, we noticed that the drag link hit the
underside of the front-driverside spring pack when turning to the right. Does
this mean that my drop pitman arm isn’t low enough?? Can I do something about
it, besides buying a new pitman arm?? Later, I cut a leave (from a spring pack)
and put it between the perch and spring pack in the front (at both sides). The
last step was adding the front brakeline extensions. We couldn’t get the rubber
line off the steel line. Then we decided to mount the brakelines under the
frame by carefully bend the brakeline. Now I have more than enough brakeline
when it extends downward during axle droop, and didn’t have to use the brake
line extensions. I don’t see a downside of this setup. I didn’t disconnect the
rear driveshaft from the rear axle, but slide it out the transfer case. I
haven’t lengthened my rear driveshaft yet, so it is very short. Later, I
installed a CV driveshaft. We connected it while I lowered the Jeep on its four
tires.

The story of getting
home (about 40 miles, again: don’t try this at home):
I HAD to drive the Jeep
back home that night. Well, I drove it home with only a half inch of the slip
yoke in the transfer case, so I had to be very careful for holes etc. (I drove
home in 4WD). I couldn’t make sharp turns to the right because of the drag link
that would hit the springpack. I couldn’t attach my exhaust system, so no
exhaust system while driving home. Because of the broken brakeline, I also
couldn’t use my brakes when I drove home. I used my emergency brake for
braking. Conclusion: I drove home while I couldn’t make sharp turns, had only a
half inch of the slip yoke in the transfer case, without an exhaust pipe and
without brakes. Maximum speed was 25 miles per hour. I’m not proud of this, but
I really had to get the Jeep home.
The result: The Jeep with SOA |
I ended up with 6"
lift in the rear and 6.5" in the front (I used 5 leaves in rear and
front). Later, I added some leaves, and now I have 7 leaves in front and 6
leaves in rear). BTW I bought SAE wrenches, but I did the whole job with metric
tools (especially the 19 mm and the 22 mm are important). I only used two torx
bits.
