Detailed Description

FAG SS3308 is a wheel seal designed for front inner wheel-end use on select Lexus GX460, Lexus GX470, Toyota 4Runner, and Toyota Tacoma applications. The seal dimensions and material selection are important for proper wheel-end sealing, and this unit uses nitrile with a metal and spring construction to support a secure seal at the bearing interface. If you are replacing a worn wheel seal on a Toyota Tacoma front inner hub or servicing a Lexus GX460 front inner wheel end, SS3308 provides the dimensional fit and sealing profile needed for the application.

This part cross-references National 710573 and AP Exhaust 28739 for the same application.

What It Helps Address

• Grease leakage at the wheel end
• Contamination from dirt, dust, and road moisture
• Premature wear in wheel bearing components
• Seal damage from age, heat, or mileage
• Noise or roughness related to compromised wheel-end sealing

Installation Notes and Tips

Verify bore diameter, seal outside diameter, and seal width before installation. Clean the hub and sealing surfaces thoroughly, and inspect the bearing and spindle area for wear or scoring before pressing in the new seal. Confirm the front inner position and vehicle-specific application for Lexus GX460, Lexus GX470, Toyota 4Runner, or Toyota Tacoma before service. The part number SS3308 should be matched to the exact wheel-end configuration listed for the vehicle.

Quality Assurance

FAG designs wheel seals to meet vehicle manufacturer specifications and works with suppliers to maintain FAG quality standards. The seal construction is intended for demanding wheel-end service where consistent sealing performance is required.
