Detailed Description

This Timken steering knuckle seal is engineered for front-end service on Ford F-250 Super Duty, Ford F-350 Super Duty, Ford E-250, and Ford Excursion applications. The seal’s ribbed inner diameter helps it seat against minor spindle wear, while the reinforced outer case supports a more secure fit during installation. Timken 710685 is also cross-referenced with National 710685 and Remy 16404 for the same application.

What It Helps Address

• Grease loss at the steering knuckle or spindle area
• Contamination from dirt, water, and road debris
• Seal leakage caused by minor spindle surface imperfections
• Heat build-up around the seal lip
• Premature wear in front steering knuckle sealing points

Installation Notes

Inspect the spindle and sealing surface before installation. Clean the area thoroughly and verify the seal seats evenly to avoid distortion. On Ford Super Duty front outer and spindle-location applications, confirm the replacement matches the original seal position before assembly.

Quality Assurance

Timken oil and grease seals are built with precision sealing features and contamination control details to support reliable front-end service. The reinforced case, ribbed sealing lip, and vented design reflect Timken’s focus on durable sealing performance in steering knuckle applications.
