Vibration in driveline? - 10/21/2007 5:38:40 PM    ryansteph   Posts: 4 Score: 0 Joined: 9/26/2007 Status: offline There is a vibration coming from the driveline.  It also clunks when coming to a stop and under initial acceleration from a stop.  Checked the driveshaft u-joints for play but the significant slop is in the transfer case.  The shaft has about 5 to 10 degrees of play.  Is this normal?  Trying to fix the clunk and need help.  Thanks.  Post #: 1

Is there anything I can do to further diagnose the problem? And, is the play in the transfer case normal? Both front and rear driveshafts have some play in the transfer case. Thanks again!

The forty bucks for new ball joints is definately worth a try rather than getting into the rear end. By the way, how difficult is replacing the pinion gear? (in reply to Use Common Sense) Post #: 6
