What This Wheel Seal Helps Address

• Grease loss at the wheel end
• Contamination from dirt, dust, and moisture
• Seal wear that can affect hub protection
• Noise or roughness related to compromised bearing lubrication
• Service issues caused by an incorrect seal size

Installation Notes and Tips

Verify bore diameter, outside diameter, and seal width before installation. Match the seal to the exact wheel end application, position, and vehicle class, since wheel seal requirements vary by setup. Clean the hub and sealing surfaces thoroughly, inspect the bearing and related components for wear, and install the seal squarely to avoid distortion.

For fitment-based searches, this FAG wheel seal is the type of part used when replacing a wheel seal on the correct vehicle application. If you are comparing wheel seal options for a make/model lookup, confirm the dimensions against the original part before service.
