FAG SS2663 Wheel Seal - Rear

Wheel Seal for Ford and Lincoln Rear Axles

The FAG SS2663 wheel seal is built for rear wheel-end service on select Ford and Lincoln applications. It uses a metal and spring seal design with nitrile sealing material to help keep contamination out and retain grease at the bearing.

Designed to meet vehicle manufacturer specifications, this seal is sized for precise wheel-end sealing where bore and outside diameter tolerances matter. The FAG SS2663 is a direct-fit style replacement for applications that require a 2.502 in bore diameter, 2.506 in outside diameter, and 1.594 in seal width.

Key Features

• Built to meet vehicle manufacturer specifications

Detailed Description

FAG SS2663 is a wheel seal engineered for wheel-end protection in driveline and axle service. Its job is to help block dirt, dust, and moisture from entering the hub area while helping prevent grease loss over the life of the bearing. The metal and spring construction supports consistent sealing, and the nitrile sealing material is selected for demanding wheel-end conditions.

This part cross-references Bosch 15960 and National 482253 for the same application. It is a strong match for rear wheel seal service on 1970-1976 Ford F-100, 1975-1979 Ford F-150, 1975-1979 Ford E-100 Econoline, 1975-1979 Ford E-100 Econoline Club Wagon, 1975-1979 Ford E-150 Econoline, 1975-1979 Ford E-150 Econoline Club Wagon, 1977-1979 Ford F-100, and 1961-1969 Lincoln Continental rear applications.

What It Helps Address

• Grease leakage at the wheel end
• Contamination from dirt, dust, and moisture
• Premature bearing wear caused by seal failure
• Wheel-end service issues on rear axle assemblies
• Seal replacement needs on Ford F-100, Ford F-150, Econoline, and Lincoln Continental rear hubs

Installation Notes and Tips

Verify bore diameter, outside diameter, seal width, and axle application before installation. Clean the hub and bearing surfaces thoroughly, and inspect the bearing and spindle for wear or scoring before pressing in the new seal. Confirm rear position fitment for the specific vehicle and axle configuration listed for the application.

Quality Assurance

FAG designs wheel seals using high-quality materials and application-specific specifications to meet manufacturer requirements. The SS2663 is engineered for demanding wheel-end sealing where precise fit and contamination control are important.
