Like many here, I have this issue as well. Drives me insane as anything 45+ is a gamble on when it's going to start wobbling all over. The front ends on these are pretty sensitive it seems.
One thing I've noticed. I have JCCapri bushings, and when I had installed those, the A Arm mounts had started to get ovaled out. The bushings are pretty tight because I installed the Cecco Braces on the a arm mounts, but I can't help but wonder if the ovaled out bolt holes are causing this.
I replaced tie rods, I replaced Ball Joints, and I replaced wheel bearings with NO CHANGE to the shaking. I even took it into the dealer to see if they could align it/get the shaking to stop and they couldn't.
Something I've learned to deal with but it's definitely frustrating. The worst is on pavement when I'm going from trail to trail. I can no longer go over 35-40 on pavement because it shakes so bad. Been getting worse with age too.
If someone figures out a fix, I'll be the first in line to try it.
