Drive/Propeller Shafts, Bearings and Joints: Testing and Inspection

1. Check that the propeller shaft universal joints and sliding splines are not seized or worn-and that the shafts are correctly aligned.

NOTE: In the event that both shafts are satisfactory, but the vibration/harshness is still present, the transfer box operation and balance of the road wheels should be checked.
