OP, be more descriptive on what side of the back noise is coming from, left turn? right turn? braking? accelerating? any modified suspension you might have to be causing it... any recent hard curb hits clutch kicking with an open diff??

we shouldn't have to ask you 20 questions to figure out YOUR problem... be as descriptive as you can...


try spraying WD40 on all bushings, and links in the rear end, including sub frame... might help for a while...
