Well a few weeks ago I developed a death wobble around 40mph. So I put an adjustable track bar on there. That didn't fix it so I put all new tie rod ends and steering stabilizer. The vibration is still there though not as bad. I have a 2000 Xj with a 3in lift with 31's. Any suggestions?

 

what about a alignment, tire rotation and balance. start with the easy stuff first. Then I would look at your ball joints. How many miles do you have and 4wd or 2wd

 

Did you check the sway bar bushings? That fixed my wobble.

 

My jeep has 173000 on it. And I'll get tires balanced and aligned. If that doesn't fix it I'll look at the sway bar thanks for the help

 

One word, ball joints. Raise the wheels about 3 inches and slide a long breaker bar under, lift wheel up and down and watch with a flashlight for any movement. I had 2 jeeps you could see movement but also one or two joints you couldnt, bottom line if you do an upper or lower you are going to do both at the same time anyway because the knuckle has to come down. Undo them both and whack it with a mallet a few times the knuckle pops right off.
I will add that mine was rock solid after doing all 4.

 

This.

Ball joints.
