Installation Notes and Tips

Confirm the shaft diameter, outside diameter, and width before installation. Inspect the pinion yoke and sealing surface for wear, scoring, or corrosion, since surface damage can shorten seal life. Clean the housing bore thoroughly and install the seal squarely to avoid distortion. Verify rear differential fluid level after service.
