Since you are posting in the Modified area, can we assume that you have a lift and bigger tires? Did it just start after adding a new component, or new tires, or hitting a big rock offroad? A little more info may be helpful.

When I did my lift I took the truck for a spin before I centered the steering wheel and the stability control started freaking out causing the truck to wobble . Is your wheel straight , if its off by more than 2 inches it could be causing the same problem. I was just going around the block and it felt pretty unstable.

Look up the term Death Wobble" in the search function. There is a lot of information there. Good luck.

ditto. Let us know your setup so we can help diagnose. Based on your symptoms sounds like bumpsteer due to lift and bigger tires.

I had the same issue. The bolt holes that secure the front track bar on both ends became elongated due to bolts becoming loose. I had to have a heavy duty washer welded onto both sides of each of the mounting brackets to fix this issue. After this fix, I still had a slight wobble from time to time. I then checked all of my bolts for the upper and lower control arms on the front and rear and found two bolts on the front control arms loose. I then tightened all control arm and track bar bolts both front and back. This cured my death wobble. I also noticed my steering damper is shot. Will replace it with after market one soon.

Compare your angles, and then look into a flip kit.

I just replaced my upper and lower ball joints and u-joints and still have this wobble. I have going to check the bolt holes and see if they are elongated as stated above.

Hopefully they are and I can fix it....it's annoying as hell....the steering wheel just shakes like crazy.

I am running a 3.5" lift and a dual steering stabilizer....so not the SS.


I am hoping it's the bolt holes.
