Re: 89 Chero auto trans mods, steering?
THere is a mod you can make to the wiring of the TCU to get what you want, I
think Bill provided it.
Re: the pitman arm: You said oversteer, do you mean bumpsteer? The drag
link should be parallel to the track bar or you will get bumpsteer. If the
DL and TB are parallel you it's a stock pitman and you should be OK. If not,
whoever installed the lift installed a drop pitman arm, and that's not good
for the front suspension on an XJ, TJ, WJ or MJ.

Re: 89 Chero auto trans mods, steering?
There we go, the King of Links has come thru again. Thanks Bill.
Matt, whatever you call it it oversteers on the curves.
I'm not sure what you mean here, the stock setup should have parellel rods,
right?
Since I have a 4 inch Skyjacker lift, your statement seems to say the
opposite. A drop pitman arm on a lift is a bad thing?

Re: 89 Chero auto trans mods, steering?
By bumpsteer, do you mean that each time you go over a bump the thing wants
to pitch sideways? I have this problem with my '02 Durango when I go over a
particular set of bumpy railroad tracks on a curved road at about 45 mph.
The dealership said "huh?"

Re: 89 Chero auto trans mods, steering?
Historical note: On CJs, YJs, FSJs and other vehicles with proper leaf
springs on the front, you had to have a drop pitman arm with a lift kit,
because the link from the pitman arm to the knuckle is designed to be
horizontal in the rest position. On your vehicles with wussy coil spring
front suspensions, there is a different steering link design, where it is
more important that the links be parallel. Here use of a drop pitman arm is
contraindicated. From what I have read here, some of the manufacturers of
lift kits for these vehicles include a drop pitman arm, because customers
expect it, because they can charge markup on it, or for some other reason
not related to sound engineering principles.
