If you put a drop pitman arm on a cherokee, do you have to drop the trac bar mount too? i have a friend giving me a 4 inch drop pitman arm from a yj that is suppose to fix my cherokee too. he told me if you dont drop the trac bar mount the same amount. i have a rustys adjustable trac bar and i need to know if i can run the DPA without lowering my track bar mount too. i as told it will cause bump steer and death wobble. with a rusty adjustable trac bar can i just run the DPA without dropping trac bar mount too.

You can get away with a 1 inch drop pitman and only suffer very minor bumpsteer, but a 4 inch drop pitman will definately require the track bar to be relocated. The drag link and track bar have to remain paralel.

I see in your details that you have a 4.5 lift and a 4 inch drop pitman arm is way to much overkill for it. Get a pitman arm from a ZJ and it will give you a 1 inch drop and be a lot less strain on your steering gear box as well.

i have 4.5 rusty kit but i have 1. 3/4 spacer on top of it. i have 6.25 inches of lift under the front of my jeep. i dont think this pitman arm is a 4 inch drop. its on a 4.5 inch rusty kit on a tj. so i think its going to be a 1 inch drop pitman arm that come with the kit. any other imput.

why does the trac bar and the drank link have to be parallel?

TBParham1925

ok this is the details i got i dont know much about the kits and what all come with them but the guy got a R.C 4 inch kit and the pitman arm is the one that come with the kit. so will i be able to use the pitmen arm on my jeep with out moving my track bar.

If it is only a 1 inch drop it will be fine. The reason the drag link and track bar need to be paralel is to prevent bumpsteer. When they are not paralel the the track bar and drag link will move at different angles. When you hit bumps in the raod or on a trail the vehicle can be forced to one side or the other without warning. Severe bumpsteer is very dangerous and could result in a serious accident.

i have had major death wobble problems every since i lifted my jeep due to trac bar being loose or tie rod ends on my trac bar. and i have just got my jeep fixed to where it wouldnt do it and my steering angles are in a bind and i an just trying to fix that cuz my jeep is also a DD.

your rustys adj tracbar will cause death, not just death wobble.

steering setup is all about angles.

This is part of that geometry class you all slept through in high school. The drag link and track bar form two parallel sides of a parallelogram. As long as they are the same length and parallel, then it can be changed and nothing will be affected. But as soon as you make those two sides not parallel, then any change to one side will make a different change to the other. This translates into bump steer.

If your steering angles are in a bind, then I suggest you check your castor angle. If you don't know how to do that, then have an alignment shop tell you what it is when they do your toe in. You did get an alignment didn't you? You have to do that after lifting. Not enough castor after lifting is a major cause of death wobble.

im going to assume that it was aligned after it was lifted. i bought a jeep that was lifted, pulled the lift and front end and rear end out of the other jeep and put it under might. yes i know i PROBABLY should have taken it to an alignment shop but i havent had them money to take it to an alignment shop. i hope to be doing this really soon though. i know its out of alignment but where im from we have several shops with alignment machines but there is only one place in town that can align a lifted vehicle and the quote i got from them is double everyone elses. i got the death wobble problem fixed after going to rustys and giving them a good cussing and making them put new ends on my tracbar every since i havent had any death wobble. i am just curious as to if it going to be more trouble then its worth to put a one inch DPA on my jeep or should i leave it stock. i dont think my drag link is completely maxed out yet but it does look like the ball joint is pretty close be being maxed out. any suggestion would be great. AND yess btw i did sleep though all of geometry class witch is probably why i dont know why the grag link and trac bar has to be parallel. but any suggestions would be great. my jeep is a daily driver and i just want some input on if yall think its going to be more trouble then its worth to put a 1"DPA or should i just leave my stock one on.

I have a RC 4.5 inch lift, but I have not changed the track bar yet, niether the pitarm. I'm about to get the RC adjustable track bar. Should I change the pitarm andwhat should I use???

I have. A 4.5 in lift and I put the dpa on for my lift, and no probs so far. I relocated the trac bar a then had it aligned. It drives wonderfully now.
