Default what causes death wobble

I just put a 3.5" lift on my 99 xj full leaf pac and new coil springs adjustable track bar, with steering stabilizer shock and new sway bar end links. Do I need adjustable upper and lower control arms.

Default Death wobble help

Hello everyone,

I have been battling death wobble and I found that the 3/8" bolt in the track bar that attaches to the axle had a lot of movement. I contacted rough country and had them send me a new bushing. I just got it in the mail and the bushing sleeve is the same thing. It is not a straight cylinder, it is obtuse. When I put the bolt in it wiggles unbelievably. I don't know if this is normal but I figures it should be snug. Any suggestions?

Did you get a alignment after you got your lift?

Why don't you just get a stronger, bigger bolt?

Yep, I had the same thing. Feel like I am going to replace everything in the front end. I'll try to post a video. My track bar bracket (stock) is weak. So I have to reinforce it. Can't post a video. I took my ipad, laid it under the jeep started it and turned the steering wheel back and forth and found that. Check you ball joints to.

Did you relocate the track bar? Is this in the original hole? The OE bolt that the hole was sized for is not 3/8", it's an M10 which is slightly larger. A poor-fitting bolt in that hole flopping around may have wallowed it out.

Yeah that to. Unfortunately I could put the lift on and the gentleman did not disclose that. I'm a fab guy so I'm taking the bracket off and putting some gusset in and building a cross bar for it. I can do it for almost nothin. So I ain't buying anything.
