Detailed Description

InMotion WS2942 is engineered as a precision seal for front differential pinion service, using polyacrylate material to maintain a tight seal under demanding driving conditions. Its measured dimensions, including a 1.875 inside diameter, 2.56 housing bore, and 2.565 outside diameter, support accurate installation and reliable sealing performance. This part is a practical choice for restoring sealing integrity on vehicles such as the Ford Bronco, Ford F-150, Ford F-250, Ford F-350, Mercury Cougar, and Lincoln Continental.

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

What It Helps Fix

• Front differential pinion seal leaks
• Contamination from dirt, road debris, and moisture
• Loss of sealing integrity around the shaft area
• Wear-related seepage in older Ford, Mercury, and Lincoln drivetrains
• Service issues during front differential maintenance

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal orientation before installation. Clean the sealing surface thoroughly and inspect the pinion area for wear, scoring, or contamination that could affect the new seal. Confirm front-position application and match the vehicle year and model exactly, especially on 1985 Ford trucks and vans with date-specific fitment notes.
