Transfer Case Output Shaft Seal Overview

InMotion WS472635 is a transfer case output shaft seal built to keep contaminants out and fluid in. It uses nitrile sealing material and precise dimensions for a secure fit in supported applications.

Fits a wide range of classic 4x4 applications, including Jeep CJ5, Jeep CJ6, and Chevrolet K10 Pickup configurations listed below. The WS472635 seal is specified for front and rear positions depending on the vehicle and transfer case setup.

Key Features

  • Nitrile sealing material for dependable fluid control.
  • Precision dimensions for proper shaft and housing engagement.
  • Helps block dirt, moisture, and debris from entering the assembly.
  • Supports leak control in transfer case service applications.
  • Fits multiple vintage Chevrolet, GMC, International, Jeep, and Willys applications.

Detailed Description

The InMotion WS472635 transfer case output shaft seal is engineered for service in older 4x4 driveline systems that use a Spicer 18 transfer case in many of the listed applications. Its nitrile construction and measured inside diameter, outside diameter, thickness, shaft diameter, and housing bore help provide a tight sealing interface where the output shaft passes through the case. This part number, WS472635, is used across a broad range of classic truck and utility platforms, including Chevrolet Blazer, GMC K15/K1500 Pickup, and Jeep CJ5 applications.

This seal is intended for buyers replacing a worn transfer case output shaft seal that may be allowing gear oil seepage, contamination intrusion, or reduced sealing performance around the shaft opening. The WS472635 part number appears in fitments for front and rear positions, so the exact application should be matched to the vehicle and transfer case configuration before installation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Service Issues

  • Fluid leakage at the transfer case output shaft.
  • Contamination entering the transfer case through a worn seal.
  • Seal hardening, cracking, or wear from age and heat.
  • Reduced sealing performance after driveline service.
  • Noise or driveline concerns related to low lubricant level.

Installation Notes

Confirm the transfer case type, shaft diameter, and housing bore before installation. Match the position and notes in the fitment data to the vehicle configuration, especially where Spicer 18 transfer case usage is specified. Clean the sealing surface thoroughly and inspect the shaft for wear or scoring before installing the new seal.

Quality Assurance

InMotion manufactures this seal with precision-focused construction and high-quality materials for reliable sealing performance in transfer case service.
