Re: Bad rumble in the rear end!!!
If you don't see any damage at the ujoints, play seems okay AND you have dissassembled the driveshaft recently Or lifted the truck without managing to dissassemble the driveshaft, check the alignment of the yokes at either end to themselves. They should be perfectly aligned with each other. If not, disconnect one end, find the alignment marks (on the end of the spline shaft and next to the boot on the socket side) and use them to reassemble the shafts properly.
