What This Seal Helps Address

• Rear differential gear oil leakage at the pinion area
• Contamination entering the axle housing through a worn seal
• Oil seepage that can leave residue around the pinion yoke
• Seal wear from age, heat, and driveline use
• Service replacement needs on classic Buick, Oldsmobile, and Pontiac rear axles

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation to confirm the seal matches the axle housing and pinion shaft. Inspect the pinion yoke and sealing surface for wear or scoring, since a damaged surface can shorten seal life. Clean the bore thoroughly and install the seal squarely to avoid distortion. Confirm the rear axle application and notes for your vehicle, especially on 1964-1967 Buick Skylark and 1968-1970 Buick Skylark listings with configuration-specific requirements.
