What This Seal Helps Address

• Gear oil leakage at the differential or wheel-end sealing surface
• Contamination from dirt, dust, and moisture entering the assembly
• Grease loss that can shorten bearing life
• Seal wear caused by age, heat, and road exposure
• Noise or service issues related to compromised drivetrain sealing

Installation Notes and Tips

• Verify bore diameter, outside diameter, and width before installation.
• Inspect the shaft and housing surface for scoring, corrosion, or wear.
• Clean the sealing area thoroughly so the lip seats evenly.
• Use the correct installation method to avoid damaging the spring or sealing lip.
• Confirm the vehicle application by year, make, model, and position before ordering.
