InMotion WS370001A Differential Pinion Seal

The InMotion WS370001A is a differential pinion seal built to maintain a tight barrier at the pinion shaft area. Made from nitrile, it helps keep moisture and road debris out while supporting leak control in the differential assembly.

Key Features

Nitrile construction for sealing performance and fluid resistance
Outside diameter: 4.855 in.
Housing bore: 4.842 in.
Shaft diameter: 3.5 in.
Width: 0.925 in.
Direct-fit style seal for differential pinion service

Detailed Description

InMotion WS370001A is a precision-machined wheel seal listed in the driveline and axles gasket and sealing systems category, with application use at the differential pinion. Its nitrile material is selected for sealing durability, while the measured dimensions help support a secure fit at the shaft and housing interface. For service work on a Ford F-150 or Chevrolet Silverado 1500, this seal is the type of component used when addressing pinion-area fluid retention and contamination control. The WS370001A is also a practical choice for technicians servicing a Dodge Ram 1500 differential where a reliable pinion seal is required.

What It Helps Address

Differential gear oil seepage at the pinion area
Contamination from dirt, water, and road debris
Wear related to an aging or hardened seal lip
Loss of sealing integrity during driveline service
Noise or driveline concerns associated with low lubricant levels

Installation Notes and Tips

Confirm shaft diameter, housing bore, and seal width before installation. Inspect the pinion yoke and sealing surface for grooves, corrosion, or damage that could affect sealing performance. Clean the bore thoroughly and install the seal squarely to avoid distortion. Verify differential fluid level after service and check for leaks during a road test.

Quality Assurance

InMotion focuses on precision fit and material selection for driveline sealing components. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

This part fits 194 vehicles

Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
