Detailed Description

SKF 18877 is designed for driveline and axle sealing where the wheel seal must keep lubricants in place and help block road contaminants from entering the assembly. The nitrile sealing surface is selected for sealing performance in automotive service environments, while the dimensional specifications help match the application requirements. This part number is used across a broad range of import and domestic vehicles, including BMW 325i, BMW 325is, BMW 525i, BMW 325iX, and Porsche 928 applications. If you are replacing a worn wheel seal on a BMW 528e, Saab 900, or Mercury Tracer rear application, SKF 18877 provides a direct service part reference.

What This Wheel Seal Helps Address

• Gear oil or lubricant seepage at the wheel end
• Contamination entering the axle or hub area
• Seal wear from age, heat, and road exposure
• Noise or rough operation caused by compromised sealing surfaces
• Maintenance needs on BMW, Porsche, Saab, Mazda, Lincoln, and Mercury driveline assemblies

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation to confirm proper fit. Inspect the sealing surface and surrounding components for wear, scoring, or contamination before installing the new seal. Clean the bore and shaft area thoroughly so the nitrile sealing lip can seat correctly. For fitment-specific service, confirm the vehicle application against the listed year and position data, including rear applications where noted.
