Alright, dilemma here. 2001 XJ with 111,000 miles. Overall in good shape and drove perfect until I threw a budget boost and some 31's on it. Now has a terrible death wobble at 55-70 if I hit even the smallest bump. Pretty sure its the trackbar, but ball joints and steering could be adding to the problem. Its basically a pavement princess for now until I finish a project at work next year then I can start taking the family camping and trail riding. So do I replace the trackbar with a good extended one and new brace/bracket, or just take the lift and tires/wheels off and put the factory ones back on until I have time to do everything right? Just don't have the time or money now to put a full lift and steering on it, but next year I will. I can slowly change out the trackbar and steering now, but will take a few months. Thanks.

 

If I was in your situation I'd return it to stock however you may still get death wobble.

 

did you get a alignment after you lifted it ? because your caster setting will change it needs to be set back up so it will want to go straight and not want to wobble .

 

I did get it lined up. Didn't help. Thank

 

What are you calling a budget boost? If it is only a 2" or even a 3" lift your stock track bar should work fine, it may just be worn out and need to be replaced with a new stock one, worn ball joints, control arm bushings, and bad tie rod ends will also cause death wobble.
