I have a 94 ZJ with the 5.2, 2 3/4" bb. I get death wobble or what I believe to be death wobble any time I go 45mph or over, anything under than and it's fine unless I hit a pot hole or something. I have replaced the tie rod and have gotten and adjustable track bar but still continue to get death wobble. I can hear my front diff whining and know that it is on it's way out. I am not sure if this is related to my death wobble or not. Any help is appreciated since this is my daily driver and I would like to drive on the hwy again.

 

Check your ball joints. I battled death wobble on my old trail ZJ. Replaced about everything up front and it finally came down to the ball joints.

 

Or hub bearings.

 

Do you still have the stock control arms? When I lifted my ZJ I had the same problem. New adjustable track bar helped but didn't get rid of it. I put a set of aftermarket cheep-o-fatbob fixed lower control arms on it and that got rid of the death wobble. Only problem was my pinion angle wasn't right anymore and the drive-line made a lot of noise. I ended up putting adjustable upper control arms on later and haven't had a problem with it again. With that said, I know many things can cause death wobble, so this was just what worked for me. Crawl under the front end and have someone turn the steering wheel back and forth and watch every single thing that moves in the system and see if there's play.

 

Its most likely the ball joints. There not that much to replace yourself. But they are a pain in the ***. If you go to a shop they charge you around $400 give or take

 

Thanks for all the responses I am hoping to get under the jeep later tonight or tomorrow to check things and see what there is play in. I will let you guys know of the findings
