Application Details

Compatible with 1998-2008 Subaru Forester, front outer; 1993-2007 Subaru Impreza, front outer; 1990-2004 Subaru Legacy, front outer; and 2000-2004 Subaru Outback, front outer. This part cross-references National 710463 for the same application.

Use the FAG SS3157 when replacing a front outer wheel seal on Subaru models that require precise sealing dimensions and a nitrile sealing surface. The seal is designed to help keep dirt, dust, and moisture out of the wheel end while helping retain grease around the bearing assembly. For Subaru Forester, Impreza, Legacy, and Outback front outer service, SS3157 provides the dimensional fit needed for proper wheel-end sealing.

What This Wheel Seal Helps Address

• Grease loss at the wheel end
• Contamination from dirt, dust, and moisture
• Seal wear that can affect bearing protection
• Leakage concerns at the front outer hub area
• Replacement needs during wheel bearing or hub service

Installation Notes and Tips

Confirm bore diameter, seal outside diameter, and seal width before installation. Clean the hub and mating surfaces thoroughly, and inspect the bearing and spindle for wear or scoring before pressing in the new seal. Verify the front outer position and vehicle application against the service information for your Subaru Forester, Impreza, Legacy, or Outback.
