Detailed Description

FAG SS2939 is a wheel seal engineered to meet vehicle manufacturer specifications for wheel-end sealing. Its nitrile sealing element and metal spring construction are selected for applications where consistent sealing performance and dimensional accuracy matter. With a 2.441-inch bore diameter, 2.447-inch outside diameter, and 1.85-inch width, this seal is sized for specific axle and hub requirements rather than universal use.

This part cross-references Gates 18862 for the same application. It also aligns with interchange reference 47x62x8 and Schaeffler global number 413 2939 100. For fitment-focused searches, this is a direct replacement option for 1998-1999 Chevrolet K1500 and K1500 Suburban, 1998-1999 GMC K1500 and K1500 Suburban, 1996-1998 Mazda MPV rear, 1989-1993 Mazda MPV rear inner, and 1984-1985 Mazda RX-7 rear applications.

What It Helps Address

• Grease loss at the wheel bearing
• Contamination from dirt, dust, and moisture
• Seal wear in high-demand wheel-end service
• Incorrect replacement sizing for application-specific hubs and axles
• Noise or bearing damage related to compromised wheel-end sealing

Installation Notes and Tips

Verify bore diameter, outside diameter, width, and vehicle application before installation. Match the seal to the correct position, since this part is used in rear and rear inner applications on Mazda models and in N/A-position driveline applications on select Chevrolet and GMC trucks and SUVs. Clean the sealing surface thoroughly and inspect the hub, axle, and bearing area for wear before installing the new seal.
