What This Seal Helps Address

• Gear oil seepage at the front right axle shaft
• Contamination entering the axle housing through a worn seal
• Fluid loss that can affect driveline lubrication
• Leak-related residue around the axle shaft and housing bore
• Seal wear from age, heat, and normal suspension movement

Installation Notes and Tips

Verify the axle type, ring gear size, and front right position before installation. Match the seal dimensions to the housing bore and shaft diameter, and inspect the sealing surface for scoring or corrosion before pressing the new seal into place. Clean the bore thoroughly so the seal seats evenly and maintains proper contact.
