What This Wheel Seal Helps Address

• Loss of sealing integrity in rear inner or front spindle applications
• Service issues tied to incorrect seal dimensions

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation to confirm the seal matches the hub or axle housing. Clean the sealing bore and shaft surface thoroughly, and inspect for grooves, corrosion, or damage that can affect sealing performance. Confirm the vehicle position and notes in the fitment data, especially for Toyota Pickup single rear wheel applications and the Mercedes-Benz 300D with 50mm spindle.
