DW (Death Wobble)

So I've been doing a ton of research on these forums and figured I'd start sharing some things that I've noticed and checked out. I've been experiencing a death wobble on a 97 Grand Cherokee Laredo. Its lifted with 31's.

So far I tightened everything up and adjusted the tire pressure which only made it worse. It appears it has lead me to the problem at hand though. Pictures show an example of what my issue appears to be. Once its not twenty degrees out I'll be tampering with it and see if its just loose or it needs to be fully replaced.

On my other Jeep, also a 97, the death wobble was resolved by tightening everything up steering component wise and that was all I needed to do for that one. It still runs quite well with no issues and this was years ago.

Just wanted to point out a few resources I've found with some of the best information about the DW topic.

What's everyone's opinion on the pictures I attached?

Is that the steering stabilizer? Lmao. Not the problem. It's usually track bar associated but it can be a combo of things.

Well that ain't right. It's not your problem either if you have death wobble, that could cause steering vibes, but not the whole enchilada.

I would bet trackbar or CA bushings.

Jumping under it again today now that it isn't twenty degrees. I did have to tighten this up quite significantly. I'll be checking my adjustable track bar to see what its up to.

On my JK, it ended up being the aluminum wheels after I went through all of what you are going through with track bars, alignment, etc...

The hub on the aluminum wheels was much thicker and the tire shop didn't get the wheels on there exactly flat to the hub. Weird but it worked for me. From then on, I rotated them myself.

Always start with caster angle. I can drive my rig with loose track bar, completely unbalanced wheels, and sloppy ball joints with no death wobble simply by dialing in the caster angle.

I'll look into that next. So far, the tierods have been replaced as there was play and so have the ball joints. Death wobble still exists. Track bar is aftermarket and solid. Steering stabilizer isn't leaking or frozen so its working no problem.

If your front control arm bushings are shot to crap it will change the castor angle and allow the axle to move around. Especially the lower bushings.

Will this be something the alignment shop will see? I'll pop out when its not pouring to investigate it the ways I know how.

It's kinda hard to tell without pulling the arm.
