Bruce, check the inboard cv on the drivers side of the coach. The 12 point
bolts thar secure the joint to the final drive flange are know to loosen
and cause the exact symptoms you describe. If they are loose, remove them,
wire wheel the threads, de-grease the internal threads with brake-kleen or
similar, and use blue loctite and retorque them to 55 foot pounds torque.
While you are under there, check your boots for tears. Check the half shaft
carrier bearing on the passenger side as well.
