Just installed a 3" lift over the winter and have had the death wobble the past 4 months. Its gotten progressively worse. Definitely need a new steering stabilizer and tie rod end to the pitman arm. Seems like the lift is effecting the angle of pitman arm to the tie rod end and breaking the tie rod end loose. Is this possible? I plan on replacing both parts, but should I worry about future problems creeping up?

 

I had the start of a death wobble, I simply replaced the Track bar and it went away.
87 XJ, 30" front and the rear actually looks more like 4"+ so it kinda stink bugs. haha.

Do a google search for death wobble and there is lots of pages explaining it and honest cures.
