Detailed Description

This differential pinion seal is engineered to help retain lubricant and block contaminants at the pinion interface, where consistent sealing is critical to differential operation. InMotion WS710640 is specified for front inner Ford E-150 and Ford E-150 Club Wagon applications, with dimensions that support a precise fit in the housing bore and around the shaft.

What It Helps Address

• Gear oil seepage at the differential pinion area
• Contamination from road debris and moisture entering the seal area
• Wear related to an aging or hardened pinion seal
• Loss of sealing integrity during differential service
• Maintenance needs on Ford E-150 front inner differential assemblies

Installation Notes and Tips

Verify shaft diameter, housing bore, and position before installation to confirm the seal matches the differential assembly. Clean the sealing surfaces thoroughly and inspect the pinion area for wear, scoring, or contamination before installing the new seal. For best results, replace the seal during differential service when the assembly is already open and accessible.
