Detailed Description

InMotion WS481837 is a differential pinion seal engineered to help keep contaminants out of the axle assembly and retain lubricant where it belongs. The nitrile sealing material is selected for driveline sealing service, and the dimensional profile supports a tight interface at the shaft and housing bore. This makes it a practical choice for rear inner and rear axle sealing jobs on vehicles such as Jeep Comanche, Jeep Cherokee, Jeep Wagoneer, Chevrolet Blazer, and GMC Jimmy when equipped with the listed axle configurations.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. The WS481837 is a direct-fit style service part for technicians and owners replacing a worn or leaking seal in the differential pinion area.

• Service replacement needs on rear inner or rear axle sealing points
• Maintenance on Jeep, Chevrolet, and GMC axle assemblies with the listed dimensions

Installation Notes and Tips

Confirm the axle configuration, seal dimensions, and position before installation. Clean the housing bore and shaft sealing surface thoroughly, and inspect for grooves, corrosion, or damage that could affect sealing performance. Proper alignment during installation helps the nitrile lip seat evenly and maintain a reliable seal.
