So, I had some noise coming from the right rear and replaced one bad pillowball and some other parts with a bit of play. But I still have a loud clunk coming from that area.

It happens during sharp turns and some shifts. It's much worse when I doing a burnout.

I don't think it's the pillowballs since there's no play in the suspension.

Could I have one bad diff mount? Or could it be the half-shaft?

 

on mine the RB muffler used to move and hit the body on left turns.. could also be a sway bar moving around, the aftermarket ones do that

if you haven't yet, its also mandatory to get under a "new to you" car and just make sure everything is tight

 

I have the same on the rear left...it does happen when pressure is put on.

 

I had the issue of the sway bar link busshing that connects the control arm and sway bar together it was loose just needed to tighten it up or it could be a shock

I had this exact same clunking problem with the RB muffler.

 

I think one of the bolts connecting the diff to the PPF was loose.
