FAG SS6245 Wheel Seal - Rear

Wheel Seal for Heavy-Duty Rear Axles

FAG SS6245 is a wheel seal built for rear axle service on select Chevrolet Silverado and GMC Sierra HD applications. It is engineered with a metal case, spring, and auxiliary lip to help keep contamination out of the wheel end while retaining grease at the bearing.

With precise dimensions and polyacrylate sealing material, this seal is designed for demanding wheel-end environments where dirt, dust, and moisture can shorten component life. FAG SS6245 is a direct-fit option for multiple rear inner and rear axle positions on Silverado 2500 HD, Silverado 3500 HD, Sierra 2500 HD, and Sierra 3500 HD models.

Detailed Description

FAG SS6245 is a wheel seal for heavy-duty driveline and axle service, with fitment across 2011-2023 Chevrolet Silverado HD and GMC Sierra HD platforms. It fits 2020-2023 Chevrolet Silverado 2500 HD, rear inner; 2020-2023 Chevrolet Silverado 3500 HD, rear inner; 2020-2023 GMC Sierra 2500 HD, rear inner; and 2019-2023 GMC Sierra 3500 HD, rear inner. It also fits earlier rear axle applications on Silverado and Sierra HD models, including 10.50-inch and 11.50-inch ring gear configurations noted in the fitment data.

This part cross-references SKF 29587A and Timken SL260069 for the same application. The SS6245 dimensions and sealing design make it a practical replacement when servicing wheel-end seals on Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, GMC Sierra 2500 HD, and GMC Sierra 3500 HD rear axle assemblies.

What It Helps Address

• Grease loss at the wheel bearing
• Contamination from dirt and dust entering the wheel end
• Moisture intrusion around the axle seal area
• Wear related to damaged or leaking rear wheel seals
• Noisy or rough wheel-end operation caused by seal failure

Installation Notes and Tips

Verify axle configuration, ring gear size, and seal dimensions before installation. Match the seal to the correct position listed in the fitment data, especially rear inner and rear applications on Silverado and Sierra HD models. Inspect the hub, spindle, and bearing surfaces for wear or scoring before installing the new seal, and confirm the sealing lip seats evenly during assembly.

Quality Assurance

FAG designs wheel seals to meet vehicle manufacturer specifications and works with suppliers to maintain FAG quality standards. The SS6245 is built for demanding wheel-end service where sealing performance and dimensional accuracy matter.
