InMotion WS710454 Wheel Seal - Rear or Rear Inner

InMotion WS710454 Differential Pinion Seal

The InMotion WS710454 is a differential pinion seal built to help keep contaminants out of the differential pinion area while maintaining a secure sealing surface. Made from fluoro-elastomer, it is specified for dimensional accuracy and consistent sealing performance in driveline service.

Compatible With applications that require a 88.5 mm inside diameter, 119.3 mm outside diameter, and 11.5 mm width, this seal is a direct-fit style service part for differential sealing repairs. The WS710454 is marked 710454 and uses JIS G3141 spring material with a JIS G3521 seal case material.

• Housing bore: 118.9 mm (4.724 in.)
• External marking: 710454
• Part number: WS710454

Detailed Description

Built for driveline sealing service, the InMotion WS710454 differential pinion seal helps maintain the barrier between internal differential components and outside contaminants such as road debris and moisture. Its measured dimensions support accurate seating in the housing bore and around the shaft interface, which is important when servicing differential pinion leaks on vehicles such as Ford F-150 and Chevrolet Silverado 1500 applications that use this seal specification. The WS710454 is also relevant for other make/model combinations that call for the same pinion seal dimensions and construction.

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

What It Helps Address

• Differential pinion seal leaks
• Contamination entering the pinion area
• Moisture intrusion around the differential seal surface
• Wear-related sealing loss at the pinion interface
• Service replacement for driveline sealing maintenance

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation to confirm the WS710454 matches the differential being serviced. Clean the sealing surfaces thoroughly, inspect the pinion yoke and bore for wear or scoring, and install the seal squarely to avoid distortion. For vehicles such as Ford F-150 and Chevrolet Silverado 1500, confirm the exact axle and differential specification before ordering.

Quality Assurance

InMotion specifies this seal with fluoro-elastomer material and controlled dimensional details to support reliable differential service. The use of JIS-standard spring and seal case materials reflects a construction focused on sealing consistency and fit accuracy.
