Detailed Description

FAG SS2641 is a drive axle shaft seal designed to meet vehicle-specific sealing requirements where precise dimensions matter. The nitrile sealing element and spring-loaded metal construction are selected to support consistent sealing at the wheel end, helping reduce contamination and lubricant loss.

This part cross-references Bosch 15820 and National 473677 for the same application.

What This Seal Helps Address

• Grease leakage at the axle or wheel end
• Contamination from road dirt, dust, and moisture
• Seal wear that can lead to bearing damage
• Noise or roughness caused by compromised wheel end lubrication
• Service issues on BMW, Honda, Toyota, Acura, Ford, Lexus, and Mercury driveline applications

Installation Notes and Tips

Verify bore diameter, outside diameter, and seal width before installation to confirm SS2641 matches the application. Clean the sealing surface thoroughly and inspect the axle shaft, hub, and bearing area for wear or scoring before fitting the new seal. For best results, install the seal squarely and avoid damaging the nitrile lip during assembly. Confirm vehicle-specific placement, since this part is used in front, rear, and rear inner positions depending on the application.
