What It Helps Address

• Gear oil seepage at the wheel or axle seal area
• Contamination entering the sealed driveline cavity
• Seal wear from age, heat, and mileage
• Noise or service issues related to lubricant loss
• Maintenance on Nissan and INFINITI rear or front axle seal locations

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation to confirm the seal matches the housing and shaft dimensions. Clean the sealing bore and shaft surface thoroughly, and inspect for grooves, corrosion, or damage that could affect sealing performance. Use proper installation tools to seat the seal evenly and avoid distortion. Confirm the exact vehicle position listed for your application, especially on front right, front left, rear, and rear inner locations.

SKF designs and manufactures seals to high quality standards using application-specific materials and bonding methods. The brand’s seal engineering heritage dates back to the first integrated shaft seal in 1928, and SKF seals have been used for decades in lubricant-retention and contamination-control applications.
