Ok.. So im at my wits end with this death wobble. Everytime I fix something it gets a little better but is still there.. So here has been the process so far. This is on an 07 JKU.. I ONLY get death wobble when I hit jarring bumps mainly with the right side that I have noticed.

Had bump steer stock. Put a zone 3" lift on... When I was finishing up didnt think to make sure the wheels were back on the ground when I snugged everything up, heard a bang when I lowered it. Lifted it back up, checked everything out loosened bolts set it back down, re torqued em. Next day death wobble.

Took it in for an alignment, was told all 4 BJs and the TREs were bad. Replaced all 4 BJs and the TREs. Got an alignment still had death wobble.

Replaced track bar with a new take off from an off road shop. Still had it.

Get another alignment. Still got it.

Replace track bar with Teraflex monster bar and replaced passenger side axle UCA bushing after having it looked at a jeep shop who said it was bad. They also said my driver side ujoint was bad, and my lower BJs were not seated by about 3mm and all 4 shocks were going (i installed em late at night so the shadow must have messed with it, but they said this shouldnt have anything to do with it. Neither would the shocks). Still got it.

Have a buddy who works on off road vehicles replace the ujoint and put new bushings in the track bar since it was a used one. As usual a bit better but still there. Though the driving mannerisms got much better. He said the holes in the track bar looked good. He didnt check the rest of the control arm bushings, but from what he could tell they were ok.

At this point about to replace all the control arm bushings with poly bushings, though im told I dont wanna do that, the ride will be too rough. And get another alignment. This is a DD that only sees light trails on the weekends.

Thoughts? Im going NUTS!!! And being a stay at home dad and full time GiBill student really doesnt afford for me to keep replacing items.

Im located in Oakland County MI if anyone knows anyone who would be able to really figure out WTF is going on with this damn thing.

 

Steering box ?
Did you have the TB holes welded up ?

 

Previously when I checked the holes they looked ok. He said he didnt notice them being walloed out when he looked. How do I check the steering box?

 

Tires balanced and rotated?

 

rotated not balanced... but it ONLY happens after hitting a bump or a small series of undulations in the road. which leads me to believe the tires are not the source

 

Have you been through this checklist?

Have somebody turn the wheel 9-3. Look for play in the pitman arm/sector shaft.

 

Any play whatsoever? My guy said he saw a little but looked like normal wear

 

Theres should be 0 play in the sector shaft.

 

Are you sure that this isn't just your stability control kicking in?
