What It Helps Address

• Contamination entering the rear driveline sealing area
• Wear-related leakage from an aging axle or differential seal
• Loss of sealing integrity caused by heat and road exposure
• Service replacement needs on Porsche 911 rear differential applications

Installation Notes

Verify shaft diameter, seal dimensions, and application position before installation. Inspect the sealing surface for scoring or wear, and replace the seal if the mating surface is damaged. Clean the housing and shaft area thoroughly so the dust lip and sealing edge seat correctly. Confirm fitment against the vehicle year and position listed for the Porsche 911 before assembly.
