Cant stop the wobble!

ok so long story short. I deployed 8 months ago and right before I left my jeep was shaking slightly at 42 mph but would stop. While deployed my wife would drive it once a week or so. She said the shaking got so bad that she couldn't drive it.mi thought she was exaggerating until I got home. It would shake like crazy once hitting 42 mph and I had to pull over and stop. So I brought it to get fixed. Turns out my rear axle shaft was bent pretty bad. I got it fixed. So I picked it up today and no shaking once I hit 42! I was so freakin happy, but then I'm cruisin at 50 and put on the breaks and it starts shaking again! Not as bad but pretty damn bad. Now if I coast to a stop it doesn't shake. Does anyone have any ideas?

Id start by checking the brakes my kids car had a horrible vibration before I replaced the front rotors.

Sounds like warped rotors. Easy fix.

Search "death wobble". It could be the ends of your front track bar are worn out. Which causes something else to wear, which messes something else up.

The bolt on the front passenger side trackbar on mine was significally undersized (smooth part was smaller diameter than threads) and I think it's a problem on many TJ's. Credit here to Unlimited for one of his threads.

It had started to wallow out the factory trackbar hole, or the factory hole was never round in the first place. I never had a wobble (even over 100), but I can see how it would originate from here.

I replaced the bolt when I put in the new JKS bar and the interface was much tighter.
