InMotion WS370371A Wheel Seal - Rear Inner

Wheel Seal for Differential Pinion Service

The InMotion WS370371A wheel seal is built for differential pinion sealing where a precise barrier against moisture, dirt, and road debris matters. Its nitrile construction and measured dimensions support a secure fit for service work on driveline sealing systems, including applications tied to Honda Civic and Toyota Corolla maintenance searches.

Key Features

• Nitrile material for sealing performance in driveline environments
• Outside diameter: 5.14 in. for housing fitment reference
• Shaft diameter: 3.937 in. for pinion-side sealing reference
• Housing bore: 5.126 in. for installation matching
• Width: 0.605 in. for dimensional verification during replacement
• InMotion part number WS370371A for catalog and cross-reference use

Detailed Description

InMotion WS370371A is a differential pinion seal engineered to maintain a tight seal at the pinion area and help keep contaminants out of sensitive internal components. The nitrile sealing material is selected for driveline use, while the listed dimensions provide the reference points needed when matching an OE-style replacement during differential service. For buyers searching for a wheel seal, differential pinion seal, or driveline gasket and sealing system component, WS370371A offers a straightforward replacement path for vehicles such as Honda Civic and Toyota Corolla where the correct seal dimensions are critical. 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 seal area
• Contamination entering the differential through a worn seal
• Seal wear caused by age, heat, and driveline movement
• Loss of sealing integrity during differential maintenance
• Fitment verification needs for Honda Civic and Toyota Corolla seal replacement searches

Installation Notes and Tips

Confirm shaft diameter, housing bore, outside diameter, and width before installation. Clean the sealing surface thoroughly and inspect the pinion area for wear, scoring, or contamination that could affect seal life. Use proper seal installation practices to keep the lip square and avoid damage during pressing. Verify the application against the vehicle’s differential specifications before final assembly.

Quality Assurance

InMotion manufactures this seal with precision-focused dimensions and nitrile material selection for driveline sealing service. Part number WS370371A should be matched to the vehicle and differential specifications before installation.
