The diff bushing was toast and just fell right out, so needless to say the clunk is fixed. The problem is now I am getting horrible whining from the rear. The noise dramatically changes tone with acceleration / deceleration. I don't think it's the diff though, as it has never made any noise whatsoever. Anyone else experience this after bushings? I'm thinking maybe the drive shaft. When I pulled the drive shaft rear CV a couple of the ball bearings fell out so I pulled them all and cleaned, re-greased them. Oh yeah, I do know all about the 8.8 fix all solution...it's coming eventually.
