Detailed Description

SKF 19623 is engineered as a wheel seal for rear outer applications where accurate sealing dimensions matter. The listed width, outside diameter, and shaft diameter help identify the correct seal for the hub and axle interface, while the polyacrylate sealing surface supports consistent contact at the sealing lip area. SKF has a long history in seal design and manufacturing, and this part reflects that focus on controlled materials and application-specific construction.

This part cross-references CHR 19623 for the same application. It fits 1998-2008 Subaru Forester, rear outer; 1993-2007 Subaru Impreza, rear outer; 2005-2006 Saab 9-2X, rear outer; and 1990-1999 Subaru Legacy, rear outer, including the 1992 Legacy split by production date. If you are searching for a Subaru Forester rear outer wheel seal, Subaru Impreza rear outer wheel seal, or Subaru Legacy rear outer wheel seal, SKF 19623 is the matching service part to verify against your vehicle and position.

What It Helps Address

• Gear oil or lubricant seepage at the wheel end
• Contamination entering the hub or axle sealing area
• Wear-related sealing loss at the rear outer position
• Noisy or rough operation caused by compromised sealing surfaces
• Service replacement for a worn Subaru or Saab rear outer wheel seal

Installation Notes and Tips

Confirm the rear outer position, shaft diameter, and outside diameter before installation. Inspect the hub, axle surface, and sealing bore for wear, scoring, or corrosion, and clean all mating surfaces before fitting the new seal. Proper seating depth and alignment are important to avoid premature leakage. Always verify vehicle year, model, and production-date notes for the 1992 Subaru Legacy before ordering.
