What It Helps Address

• Gear oil or lubricant seepage at the wheel end
• Contamination entering the axle or hub area
• Seal wear from age, heat, and mileage
• Noise or service issues related to compromised rear axle sealing
• Maintenance needs on Subaru rear center and rear outer seal locations

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation to confirm the SKF 19603 matches the housing and shaft dimensions. Inspect the sealing surface for scoring or wear, and clean the bore and shaft area thoroughly before fitting the new seal. For best results, install the seal squarely to avoid distortion of the nitrile lip and to maintain proper contact on the sealing surface.

SKF manufactures seals to specific designs and quality standards intended to support long service life and dependable sealing performance. The brand’s seal engineering heritage includes the first integrated shaft seal, and SKF continues to apply that experience to driveline sealing products such as the 19603 wheel seal.
