Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation to confirm the seal matches the differential housing and pinion shaft. Inspect the pinion yoke and sealing surface for wear or scoring, and replace damaged mating surfaces before installing the new seal. Clean the housing thoroughly so the nitrile sealing lip seats evenly.
