FAG SS2915 Wheel Seal - Rear Outer

Wheel Seal for Rear Outer Applications

The FAG SS2915 wheel seal is built for rear outer wheel-end service on select Buick models from the 1950s and 1954-1955 model years. It uses a metal seal type with nitrile sealing material to help keep contamination out of the wheel end and retain grease at the bearing.

For restorations and maintenance on classic Buick Century, Roadmaster, and Skylark applications, the FAG SS2915 is specified to match the required wheel-end dimensions and sealing design.

Detailed Description

FAG SS2915 is a wheel seal designed around demanding wheel-end specifications, with dimensions that matter for proper sealing performance and bearing protection. The metal construction and nitrile sealing material are selected to support a secure seal at the rear outer wheel position, where contamination control and grease retention are critical. This part number is listed for 1950-1955 Buick Roadmaster, 1954-1955 Buick Century, and 1954 Buick Skylark rear outer applications. The SS2915 also cross-references Gates 18704 for the same application.

What It Helps Address

• Grease leakage at the wheel end
• Dirt and dust intrusion into the bearing area
• Moisture contamination around the hub
• Wear caused by compromised wheel-end sealing
• Incorrect seal sizing for specified Buick rear outer applications

Installation Notes and Tips

Verify the bore diameter, seal outside diameter, and seal width against the hub and bearing specification before installation. Confirm rear outer position fitment for the exact vehicle and application, since wheel seals are position-specific. Clean the sealing surfaces thoroughly and inspect the hub and bearing components for wear or damage before installing the new seal.

Quality Assurance

FAG designs wheel seals to meet vehicle manufacturer specifications and works with suppliers to produce seals that align with FAG quality standards. The SS2915 is built for the dimensional and material requirements of the listed Buick applications, including Buick Century, Buick Roadmaster, and Buick Skylark rear outer service.
