I get a multiple 2-3X bump on the floorpan/body on acceleration from a dead stop. It reminds me of the pinion bumper noise I used to get on hard aceleration from pinion wrap-up on my Mopar, except this is an independent rear. Is there some sort of rubber isolator/bumper somwhere that's bad now? Any pictures? Experience? Just turned 101k last week although I've noticed it previously. I originally thought it was the transmission mount so I changed it, no help. Checked the carrier bearing for the drive shaft & it feels good too. Thanks.
