Default Rear upper control arm squeaks and knocks

I've been having this problem for a while now. Even changed the rear upper control arm. The new one does the same thing. I thought the bushings were worn so I changed the arm. No luck. Same issues. When I move it with my hands I can see movement in the bussing area. The bushings on the passenger side, where I'm having the issue seems to be smaller than the ones on the drivers side. Can I get any suggestions? Thanks in advance. Oh FYI it rides terrible on that side. You can feel every rock and pebble in the road.

The bolts are stripped. They won't get tight enough.

Bolts are stripped and so is the nut on the rear. I'm in the process of trying to re thread it.

Re-threaded the nut and added a new bolt. It tightened up pretty good. The knock is gone. But it still squeaks like crazy.
