8 3/4 rear clunk when brakes are applied

Sounds like slop in ring and pinion. normally more noticeable with an automatic, going from park to r or d, not necessarily from brakeing? You might want to pull drums, see if any brake hardware has come loose. the adjusters may not be working properly, giving a lot of play, and when you hit the brakes, bam. update us on resolve:happy10:
