Detailed Description

InMotion WS6985 is engineered as a sealing solution for differential pinion service, using felt construction to form a secure barrier against debris and moisture. The listed dimensions are important for proper sealing performance: the 1.875-inch inside diameter and shaft diameter align with the shaft interface, while the 2.633-inch outside diameter and 2.628-inch housing bore support a controlled fit in the housing. For restorations and maintenance on 1955-1957 Chevrolet Bel Air and 1955-1957 Pontiac Laurentian front inner applications, this seal supports leak control and helps protect internal differential components from contamination. The WS6985 is a practical choice when servicing classic driveline assemblies that require accurate sealing dimensions.

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

Common Issues This Seal Can Address

• Gear oil seepage at the differential pinion area
• Contamination entering the pinion seal interface
• Wear-related sealing loss from an aged felt seal
• Moisture intrusion around the housing bore
• Reduced protection for sensitive internal differential components

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation to confirm the WS6985 matches the service opening. Clean the sealing surfaces thoroughly and inspect the pinion area for wear, scoring, or debris that could affect sealing performance. For 1955-1957 Chevrolet Bel Air and Pontiac Laurentian front inner service, confirm the application position before assembly.
