Detailed Description

InMotion WS470331N is a differential pinion seal engineered for precise sealing performance in driveline and axle service. The polyacrylate construction is selected for sealing durability, while the listed dimensions help ensure proper seating at the housing bore and shaft interface. This seal is specified for rear outer positions on Jeep vehicles equipped with Spicer 35C Axle or AMC 20 Axle configurations, making it a practical replacement for service work on older Jeep driveline systems. 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 area
• Contamination from dirt, debris, and moisture entering the axle assembly
• Seal wear that can lead to driveline fluid loss
• Service issues on Jeep rear axle pinion sealing points
• Maintenance needs on aging Spicer 35C and AMC 20 axle setups

Installation Notes and Tips

Verify axle type, position, and seal dimensions before installation. Inspect the pinion surface and housing bore for wear, scoring, or corrosion before pressing in the new seal. Clean the sealing area thoroughly and confirm the seal is seated evenly to help maintain proper contact at the pinion shaft.
