I have recently helped a friend install a rough country 4 inch lift on his WJ, after install of the lift we have had some serious death woblle at speeds over 40mph. We have tried everything, drop pitman arm, new tie rod end at pitman arm, rustys trac bar, moog trail boss steering stabilizer. Trac is perfect, he had it aligned but he doesnt know what specs the shop aligned it to because he threw away his print out like a dumass. So I dont know if the truck was aligned correctly for the lift.

List of installed parts:
4" coils
rough country shocks
rustys adjustable trac bar
rough country drop pitman arm
napa tie rod end at pitman arm
MOOG trail boss steering stabilizer

We have the heavy duty control arms that came with the kit but not installed yet, are they longer? and will they fix caster issues?

Also have control arm drop bracket for rear not installed yet

Any help would be much appreciated cause we are stumped!!

I'm no expert. BUT, I did a lift and installed a new set of tires on an Expedition and had a weird wobble once. Turned out one of the tires I bought was bad. I got the new set of tires online.

Let me be the the first to say,use the search function or Google.

Not an expert but you could try transfer case lowering, balancing/new tires. just my two cents

I did, believe me posting a thread is a last resort for me... Im just trying to find some live help...

I installed lower control arms made a small difference.

tires are not new and they are balanced.

Im just running out of ideas to fix the mfer

i did the lift on my 00 wj, you have to put a real heim joint in the trac bar, not a fake one from RX, i used one from rustys off road, also ur camber must be between 5-7 degrees and i ended up using a dual steering stabilizer setup instead of a single. get ur whole front end aligned. its like 120-150 to get it done.
