SKF 16406 Transfer Case Input Shaft Seal - Rear

SKF 16406 Transfer Case Input Shaft Seal

The SKF 16406 transfer case input shaft seal is built for applications that need a precise seal at the transfer case input shaft. With a nitrile sealing surface and a 1.625-inch shaft diameter, this seal is specified to help maintain lubricant control where the shaft enters the transfer case housing.

SKF has a long history in shaft seal design, and this part reflects that experience with application-specific materials and dimensions. It is a direct-fit style transfer case input shaft seal for select vehicle applications, including Jeep and Dodge models where this seal size is required.

Detailed Description

SKF 16406 is a transfer case input shaft seal engineered around the listed dimensions for proper sealing at the transfer case input shaft. The nitrile sealing surface is selected for drivetrain environments where exposure to lubricant and road contamination is common. For buyers searching for a Jeep transfer case input shaft seal or a Dodge transfer case seal by part number 16406, this component provides a focused replacement option for the correct application.

This part cross-references Continental 50078 for the same application. When replacing a worn transfer case seal, matching the shaft diameter, outside diameter, and width is critical to achieving the correct seal fit and reducing leakage at the input shaft area.

What It Helps Address

• Transfer case fluid leaking at the input shaft
• Oil seepage around the transfer case housing
• Contamination entering the transfer case through a worn seal
• Seal wear from age, heat, and drivetrain movement
• Noise or drivability concerns caused by low transfer case fluid level

Installation Notes and Tips

Verify the shaft diameter, outside diameter, and width against the removed seal before installation. Clean the seal bore and shaft surface thoroughly, and inspect the input shaft for grooves or damage that could affect sealing. Proper alignment during installation helps prevent distortion of the nitrile sealing lip and supports a reliable seal at the transfer case input shaft.

Quality Assurance

SKF designs and manufactures seals to specific application requirements using premium materials and controlled production standards. The brand’s seal engineering background supports long service life and dependable sealing performance in drivetrain applications.
