Important: To help ensure optimum performance, the drive shaft assemblies are
specially balanced as a unit at the factory. When servicing any flange

manual for ordering information.
1. Raise the drive shaft assembly into position. The slip-yoke end of the
drive shaft mounts toward the axle. If reinstalling a drive shaft

marks made during removal.
Important: Yokes at both ends of the drive shaft must be in the same plane to
help prevent excessive vibration.
2. Install the four capscrews and two straps securing the bearing crosses
