Can't tell where its coming from, but when I put my (2002 2500 5-speed) in reverse and start backing up real slow it feels like there is a wobble in the drive train. Either the drive shaft or something in the rear end, I can't tell. Anyone heard anything along these lines. Help would be greatly appreciated before I take it to a shop.


Thanks, Ronnie

 

Check the transmission mount (the rubber block on the tranny crossmember) if it's loose or the metal has separated from the rubber it can cause this funny feeling.
it's easily checked by trying to lift the tailshaft of the tranny while looking at the mount.
Do also check the 2 front engine mounts.
