• Fluid loss that can lead to noisy or damaged driveline components
• Seal wear caused by age, heat, or shaft movement
• Service issues during differential rebuilds or axle maintenance

Installation Notes and Tips

Confirm shaft diameter, outside diameter, and width before installation. Inspect the pinion yoke or shaft surface for grooves, rust, or scoring that can affect sealing performance. Clean the sealing bore thoroughly and verify the seal seats squarely during installation. For best results, match the replacement seal to the original application by part number and dimensions.
