What This Seal Helps Address

• Differential oil seepage at the pinion area
• Contamination from road debris and moisture
• Wear on internal differential components caused by poor sealing
• Seal replacement needs during rear axle service
• Maintenance on Chevrolet C10, GMC Jimmy, and Corvette rear outer applications

Installation Notes

Confirm the axle or differential designation before ordering, since this seal is used across multiple GMC axle and differential variants. Verify the inside diameter, outside diameter, thickness, shaft diameter, and housing bore against the original seal to ensure proper seating. For best results, inspect the pinion surface and surrounding housing for wear or damage before installation.

Quality Assurance

InMotion manufactures this differential pinion seal with precision-focused construction and high-quality materials to support a secure, reliable seal in demanding driveline service. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
