InMotion WS40566S Wheel Seal - Front Inner

Wheel Seal for Differential Pinion Service

The InMotion WS40566S wheel seal is built with nitrile material to help maintain a secure seal at the differential pinion area. It is sized for a 2.125 inside diameter, 2.879 outside diameter, and 0.25 width to support a precise fit where sealing accuracy matters.

Key Features

• Nitrile construction for sealing performance in driveline applications
• Inside diameter: 2.125
• Outside diameter: 2.879
• Width: 0.25
• Shaft diameter: 2.125
• Housing bore: 2.875
• InMotion WS40566S for differential pinion sealing service

Detailed Description

InMotion WS40566S is a precision seal for the differential pinion area, built to help block contaminants such as moisture and road debris from entering sensitive internal driveline components. The nitrile sealing material supports leak control and consistent contact at the shaft and housing interface. For drivers and technicians servicing driveline and axle sealing systems on vehicles such as Ford F-150 and Chevrolet Silverado 1500, this seal provides the dimensional accuracy needed for a proper repair. The InMotion WS40566S is also a practical choice when replacing a worn pinion seal during differential maintenance.

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

What It Helps Address

• Differential fluid seepage at the pinion seal area
• Contamination from dirt, water, and road debris
• Wear-related sealing loss at the shaft interface
• Maintenance issues tied to a compromised differential seal
• Noise or driveline concerns associated with low fluid levels

Installation Notes and Tips

Verify shaft diameter and housing bore measurements before installation to confirm the seal dimensions match the application. Clean the sealing surface thoroughly and inspect the pinion area for wear, scoring, or contamination before fitting the new seal. For vehicle-specific service on Ford F-150 or Chevrolet Silverado 1500 driveline repairs, follow the manufacturer service procedure and torque specifications.

Quality Assurance

Built by InMotion using nitrile material and precision dimensions for differential pinion sealing service. Part number WS40566S identifies this seal for ordering and application matching.
