What It Helps Address

• Transfer case fluid seepage at the input shaft
• Contamination entering the transfer case through a worn seal
• Seal wear from age, heat, and drivetrain movement
• Noise or drivability concerns caused by low lubricant level after leakage
• Repeat leaks after prior seal deterioration

Installation Notes and Tips

Confirm shaft diameter and seal dimensions before installation. Inspect the input shaft sealing surface for scoring, corrosion, or wear that could affect sealing performance. Clean the bore and surrounding area thoroughly, and install the seal squarely to avoid distortion. Verify transfer case fluid level after service.
