FAG SS4815 Drive Axle Shaft Seal - Front Left, Front Left Inner or Front Left Outer

Drive Axle Shaft Seal for OE-Style Wheel End Protection

The FAG SS4815 drive axle shaft seal is built for front axle applications that need reliable sealing at the wheel end. It helps keep dirt, dust, and moisture out while retaining grease around the bearing area, supporting consistent operation in demanding driveline service.

Compatible With select Chevrolet Trailblazer, GMC Envoy, Saab 9-7x, Buick Rainier, Isuzu Ascender, and related applications, this seal is specified for front left outer, front left inner, and front left positions depending on vehicle configuration. FAG SS4815 is engineered to match vehicle-specific requirements for bore size, outside diameter, and seal width.

Detailed Description

FAG SS4815 is a precision drive axle shaft seal designed around the dimensional and sealing demands of wheel-end service. Its metal, spring, and auxiliary-lip construction works with nitrile sealing material to help maintain a stable seal at the axle shaft while resisting contamination from road debris, moisture, and dust. This makes it a practical choice for front axle service on vehicles such as the Chevrolet Trailblazer, GMC Envoy, and Saab 9-7x, where correct seal dimensions are critical to bearing-area protection.

This part cross-references Quality-Built 15618 for the same application.

What It Helps Address

• Grease loss at the wheel end
• Contamination entering the bearing/seal area
• Seal wear from age, mileage, or road exposure
• Noise or roughness related to compromised axle sealing
• Service replacement for front left outer, front left inner, or front left seal positions

Installation Notes and Tips

Verify the axle position before ordering, since this seal is listed for front left outer, front left inner, and front left applications depending on vehicle. Confirm bore diameter, outside diameter, and seal width against the original part and the hub or axle housing before installation. Clean the sealing surface thoroughly and inspect the shaft, hub, and bearing area for wear or scoring that could affect seal performance.

Quality Assurance

FAG designs wheel seals using high-quality materials and application-specific specifications to meet vehicle manufacturer requirements. The SS4815 follows that approach with dimensions and sealing features selected for the listed driveline applications.
