Detailed Description

The FAG SS2608 is a drive axle shaft seal designed for demanding wheel-end service. Its metal, spring, and auxiliary-lip construction supports sealing performance at the axle shaft while the polyacrylate sealing material helps maintain contact under operating conditions.

What It Helps Address

• Grease leakage at the front inner axle shaft seal
• Contamination from dirt, dust, and moisture entering the wheel end
• Seal wear that can affect bearing protection
• Service issues related to incorrect seal dimensions
• Front axle maintenance on Ford Super Duty and Excursion platforms

Installation Notes and Tips

Verify the axle seal dimensions, seal type, and front inner position before installation. Clean the bore and shaft sealing surface thoroughly, and inspect the bearing area for wear or contamination before pressing in the new seal. Confirm vehicle application by year, model, and position; this FAG SS2608 seal is listed for specific Ford front inner driveline applications only.
