Installation Notes and Tips

Verify shaft diameter, housing bore, and width before installation to confirm the seal matches the application. Inspect the sealing surface for scoring or corrosion, and clean the bore thoroughly before pressing the seal into place. For best results, replace the seal during differential service when the area is already open and accessible. Confirm the vehicle position as front inner before ordering or installing WS4904.
