Detailed Product Overview

This InMotion seal is engineered for a precise fit at the differential pinion area, where contamination control and leak prevention are critical. The nitrile material is selected for sealing durability, while the listed dimensions help confirm fitment during service work. Use WS9015S when replacing a worn seal on front inner driveline applications for Chevrolet C10 Suburban and GMC van or truck platforms from the early 1960s through the early 1970s. This part number, WS9015S, is a direct reference for identifying the correct seal during differential maintenance.

Common Problems This Seal Addresses

• Gear oil seepage at the differential pinion area
• Contamination from dirt, road debris, and moisture
• Seal wear that can lead to driveline fluid loss
• Maintenance issues on front inner differential service points
• Fitment verification for older GMC and Chevrolet applications

Installation Notes and Tips

Confirm shaft diameter, housing bore, inside diameter, outside diameter, and width before installation. Clean the sealing surface thoroughly and inspect the mating components for wear or scoring before pressing in the new seal. Verify the vehicle position as front inner and match the application notes for drum brake or disc brake configurations where listed.
