Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation. Inspect the pinion yoke and sealing surface for grooves, corrosion, or damage, since a worn surface can shorten seal life. Clean the housing bore and mating surfaces thoroughly, and confirm the differential configuration matches the vehicle notes before assembly. For best results, follow the vehicle service procedure for pinion preload and torque specifications.
