Common Problems This Seal Helps Address

• Grease leakage at the wheel end
• Contamination from dirt, dust, and road moisture
• Premature wear of wheel bearings and related components
• Seal failure caused by incorrect size or position-specific fitment
• Noisy or rough wheel-end operation linked to worn sealing surfaces

Installation Notes and Tips

• Verify the vehicle position before ordering; this seal is used in rear outer, rear, and rear inner locations depending on application.
• Confirm bore diameter, outside diameter, and width against the original seal before installation.
• Inspect the hub, spindle, and bearing surfaces for wear or scoring before pressing in the new seal.
• Clean the sealing area thoroughly so the nitrile lip can seat properly.
• Use the exact application listing for Jaguar XK8, XKR, XJ8, XJR, XJ6, XJ12, XJS, and Vanden Plas models.
