2000 GMC Safari SL 4.3L Rear Diff?
Posted to GM PowerTrain on 1/10/2005 14 Replies

This rig has a rhythmic drivetrain thump, thump, thump... that appears to be related to driveline speed. Its not real loud but bothers the owner. He will trade it off if the whole rear end needs overhaul so we though we would try to come up with a lesser dolla...
