1998 Jeep Wrangler (SE) - was my first car when I was 16, just got it back after all these years (same exact car). Changed out the tires to 31x10.5x15 (no lift) and now I have shaking and loud noise after a few weeks of driving on the new tires. Shot the attached video to try and get a look at it. Can see much better at the very end of the video what is happening with the rear axle. Looking for assistance on the issue - bad angle now? Joint issue? other?

Thanks! This forum has been super helpful for the minor issues I've had to fix but this one is beyond my expertise...

@Jerry Bransford - after reading through a lot of different posts - seems like your the guy i want to ask!

Looks like your upper control arms aren't attached anymore or something. Could you post some good pics from the underside of the rear axle area? Your axle should not be able to flop up and down at all.

Agreed. There is a huge amount of axle wrap. Something is going on with the rear control arms.

Maybe I should clarify, Do you know what control arms are and what they do? There should be 4 arms that connect your axel to the frame. Two uppers and two lowers, one set on each on each side of the axel, they stop the axel from rotating, and keep the axel in place. Should be pretty easy to see what's wrong once you crawl under there.
