Driveline vibration

Thanks for all the info, I pulled off the tailshaft housing and the bearing is worn so I have ordered a new one. I also am going to take my driveshaft to a different shop and see if they recognize there still is an issue. Since the housing is off I have replaced the bushing too.

While you have it apart, measure the inside diameter of the newly installed bushing and the outside diameter of the yoke tube. A buddy of mine has traced a similar vibration problem to excessive clearance between the two components on his Mopar.
