InMotion WS473212 Wheel Seal - Rear Inner

Wheel Seal for Differential Pinion Service

The InMotion WS473212 wheel seal is built for differential pinion sealing where a precise barrier against dirt, moisture, and lubricant loss matters. Made from nitrile, it uses a 1.312 in inside diameter, 2.254 in outside diameter, and 0.312 in width to match the specified shaft and housing dimensions.

Compatible with Jeep rear inner applications, including Cherokee, Comanche, Wagoneer, and Wrangler models listed below, this seal supports service work on Spicer 35 axle setups and the noted Wrangler exception.

Detailed Description

WS473212 is a precision differential pinion seal engineered to help keep contaminants out of the differential while retaining lubricant at the pinion area. The nitrile construction is selected for sealing performance in driveline service, and the dimensional specs are important for proper seating in the housing bore and on the shaft. This part number, WS473212, is listed for rear inner applications on Jeep Cherokee, Jeep Comanche, Jeep Wagoneer, and Jeep Wrangler models from 1984 through 1989.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Seal Helps Address

• Gear oil seepage at the differential pinion area
• Contamination from road debris and moisture entering the housing
• Wear caused by inadequate sealing at the pinion interface
• Service issues on rear inner Jeep driveline applications
• Seal replacement needs on Spicer 35 axle-equipped vehicles

Installation Notes and Tips

Verify shaft diameter, housing bore, and width before installation to confirm the seal matches the differential housing. Inspect the pinion surface for scoring or wear, and clean the bore thoroughly so the seal seats evenly. For Jeep Cherokee, Comanche, and Wagoneer applications with Spicer 35 Axle, confirm the rear inner position before assembly. For 1987 Jeep Wrangler, confirm the axle is not the Heavy Duty Axle version.

Quality Assurance

InMotion focuses on precision-fit sealing components built from quality materials for driveline service. WS473212 is specified to provide a secure seal at the differential pinion area when installed in the correct application.
