A wobble triggered only by a random bump in the road is not tire/wheel related and has nothing to do with balancing.

One of the problems I have been facing when trying to find mine that it will always trigger with a bump, but sometimes I am able to go 50mph and have no trouble and then others I start getting it at 35mph.

The same bump can be handled or it can start a wobble. Pretty much any bump over 40 will cause it.

I have watched all your videos and even posted some of mine mimicking the same tests for worn parts. Had multiple shops look at it and they basically look like they are using your plan to a T.

Bolts are on the track bar. I did notice that the OEM track bar bolts left thread groves in the bushings and allowed for a little extra play. I replace the 14mm bolts with 9/16 shoulder bolts. Notice a decent improvement. However the problem still exists 10% of the time of what it was. So a lot better but still need to dig deeper.

This I will do!!!!

I disagree with this...

I had at bad shimmy at about 50MPH every time I hit a bump. I thought it was my trackbar bolts and checked everything I possibly could and re tightened everything on the front end.

about a week later i got some new tires mounted on the jeep. What do you know, the shimmy went away.

= not random. It was predictable and easily repeatable at a given speed.

Has anyone tried checking the steering stabilizer? It wears out just like shocks.

When it started the first thing I did was disconnect the SS. Have had it connected and disconnected at various times with no change.
