I had the same problem at high speeds. All TREs, alignment and everything was good. I even thought the steering stabilizer shock seemed good. Just for kicks, I replaced the Steering shock. Death Wobble Gone. Don't know if this is your problem, but worth a thought.

 

9 times out of 10 a steering stabilizer is just covers the problem. A well tuned suspension shouldn't need a stabilizer at any size or speed.

I run 35's on my trail rig and haven't had a stabilizer in 8 years.

Ultimately, stabilizers are optional...

 

did you align it after replacing the tres, you didn't mention if you did.

 

yup! i didn't the alignment 4 times already. just to mess with the specs to see if changing it would make a difference and its all the same so far.

 

then balancing seems like your best bet

 

yea other than control arms, thats about all that is left.
