Detailed Description

What It Helps Address

• Transfer case fluid leaking from the input shaft area
• Contamination entering the transfer case through a worn seal
• Fluid loss that can lead to low lubrication levels
• Seal wear from age, heat, and drivetrain use
• Service replacement during transfer case maintenance

Installation Notes and Tips

Confirm shaft diameter, outside diameter, and width before installation to match the transfer case housing and input shaft. Inspect the shaft surface for grooves, corrosion, or damage that could affect sealing performance. Clean the sealing bore thoroughly and install the seal squarely to avoid distortion. Verify the application by year, make, model, and position, since some listings include front or rear transfer case configurations and production-date notes.
