Outta balance tires or messed up rims or tires can cause what your describing on a jeep. So can allotta other stuff. It' s an easy place to start though.

 

I had a similar issues. Checked and my steering stabilizer was bent and leaking. Most likely from a trail ride hit. I had nangulator's shop check everything over, had a front end alignment done (It needed some adjustment after I went to 35's) and replaced the steering stabilizer with the Teraflex one. Also rechecked torque on the adjustable sway bar. Issues was fixed. May add adjustable lower front arms to help add caster some time soon but for now it's back to normal. Took a few days of driving over bumps to finally unclinch.

 

Sounds like bumpsteer to me too - probably need to lower your trackbar and drag link.

 

X2. You do know when death wobble happens, there is no question what it is when you experience it. My jeep didn't stop shaking until I came to a complete stop.

 

well i couldnt reproduce the problem last night infact it road smooth as hell on all bumps so i dont know what the hell is up.

if its bump steer how do i correct it or what is causing it to have only showed up and disappear in two days. im sure it will happen again
