Wheel Seal for Front Inner Applications

The InMotion WS4740 wheel seal is built for front inner axle locations where keeping contaminants out is critical. Made from nitrile and sized for a precise housing and shaft fit, it helps maintain a secure barrier against moisture, dirt, and debris in the differential and hub area.

Compatible With 1991-2002 Chevrolet, GMC, and Dodge front inner applications, including heavy-duty brake and axle-specific configurations on select models. The WS4740 is a direct-fit sealing component for service work on trucks, vans, and chassis-cab platforms that rely on accurate seal dimensions.

Detailed Description

InMotion WS4740 is a front inner wheel seal engineered for driveline and axle sealing applications where dimensional accuracy matters. Its nitrile sealing material is selected for dependable contact at the shaft and housing interface, helping retain lubricant while blocking road grit and moisture from entering sensitive internal components. The seal dimensions are matched to a 2.18-inch shaft diameter and a 2.999-inch housing bore, making it a practical service part for vehicles such as Chevrolet Express 2500, Chevrolet C2500, GMC Savana 3500, and Dodge Ram 2500. The WS4740 part number is also useful when cross-checking service records or ordering replacement seals for the same application.

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

What It Helps Address

Gear oil seepage at the front inner wheel seal location
Contamination from dirt, water, and road debris entering the axle area
Seal wear caused by age, mileage, or heat exposure
Loss of sealing integrity during differential or hub service
Noise or driveline concerns related to lubricant loss

Installation Notes and Tips

Verify the shaft diameter, housing bore, and seal width before installation to confirm the WS4740 matches the service opening. Clean the bore and shaft surface thoroughly, inspect for scoring or corrosion, and install the seal squarely to avoid distortion. For best results, compare the old seal’s dimensions and position against the vehicle listing before assembly.
