InMotion WS100712V Differential Pinion Seal

Differential Pinion Seal for Spicer Axles

The InMotion WS100712V differential pinion seal is built for axle assemblies that need a precise sealing surface at the pinion. Made from fluoro-elastomer, it helps keep contaminants out and gear oil in, supporting clean operation in demanding driveline conditions.

Use this seal for service work on Spicer 44, Spicer 44-1HD, Spicer 50, and Spicer 60 axle applications found in trucks and SUVs such as Chevrolet Silverado 1500, Ford F-250 Super Duty, and Jeep Wrangler.

Detailed Description

InMotion WS100712V is a differential pinion seal engineered to create a tight barrier at the pinion area of the axle housing. Its fluoro-elastomer material is selected for durability in the presence of gear oil, road debris, and moisture, helping maintain a reliable seal where the pinion shaft enters the differential. This makes it a practical replacement for axle service on vehicles including Chevrolet Silverado 1500, GMC Sierra 1500, Ford F-250 Super Duty, Nissan Frontier, and Jeep Grand Cherokee with the specified Spicer axle configurations. This part number, WS100712V, is also a useful reference when sourcing the correct seal for rear or front axle applications listed below.

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

What It Helps Address

• Gear oil seepage at the differential pinion area
• Contamination entering the axle through a worn seal
• Seal wear from age, heat, and driveline movement
• Maintenance needs during differential service or axle rebuilds
• Noise or driveline concerns caused by low lubricant level from leaks

Installation Notes and Tips

Confirm axle type, position, and housing dimensions before installation. This seal is listed for rear, rear outer, and front applications depending on vehicle and axle configuration. Verify the shaft diameter and housing bore against the existing component, and inspect the pinion surface for wear or scoring before installing WS100712V. Proper installation and pinion preload checks are important during differential service.
