• Fitment-based replacement for front differential service on select Lexus and Toyota vehicles.
• Part number WS710187 for easy identification during ordering and service lookup.

Detailed Description

InMotion WS710187 is an engine sealing component used in differential pinion service, where a reliable barrier is needed to help protect internal parts from contamination and fluid escape. The polyacrylate seal material and specified inside diameter, outside diameter, thickness, shaft diameter, and housing bore dimensions support accurate service replacement. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Fits 1996-1997 Lexus LX450, front. Fits 1993-1997 Toyota Land Cruiser, front. Fits 1989-1992 Toyota Cressida, front. Fits 1986-1992 Toyota Supra, front. WS710187 is a practical choice for differential maintenance on Toyota Land Cruiser and Lexus LX450 applications where sealing integrity matters.

What It Is Used For

• Stopping gear oil leaks at the differential pinion area.
• Keeping dirt and moisture away from internal drivetrain components.
• Replacing a worn or hardened seal during differential service.
• Restoring sealing performance after contamination or age-related wear.

Installation Notes and Tips

Confirm shaft diameter and housing bore measurements before installation. Inspect the sealing surface for wear, scoring, or contamination, and clean the area thoroughly before fitting the new seal. Verify front-position application and match the part number WS710187 to the vehicle service requirements before assembly.
