I believe I've got the same problem on my Safari 2002 AWD. One mechanic said that he thinks it has to do with a clutch-type plate in the rear differential which is slipping, creating a kind of thumping under acceleration and even deceleration. His solution is to open up the differential, replace the fluid and add a prescribed GMC additive that will reduce the problem although not completely solve it, at a cost of approximately $125. Apparently he had to do the same job on a RendezVous.
If there's another more accurate analysis of to this problem, I'd like to hear it.
By the way, how can I access the discussion #1636 mentioned in the # 3 box above?
