Detailed Description

The InMotion WS471645 steering gear input shaft seal is engineered for vehicles that require a Ford Design sealing solution. Its nitrile construction and measured dimensions help create a secure seal at the input shaft, reducing the chance of contamination and fluid loss in the steering gear assembly. This part number, WS471645, covers a broad range of classic and later Ford-based platforms, including the Ford Ranger, Ford F-150, and Ford Mustang.

Because steering gear seals are critical to keeping internal components protected, correct sizing matters. The listed shaft diameter, housing bore, and seal width provide the dimensional reference needed for fitment verification before service. This seal is used on applications spanning Ford, Lincoln, Mercury, and Mazda models with Ford Design, making it a practical replacement for many steering gear rebuilds.

What It Helps Address

• Fluid seepage at the steering gear input shaft.
• Contamination from dirt and moisture entering the steering assembly.
• Wear related to degraded sealing surfaces.
• Loss of sealing integrity during steering gear service.
• Fitment issues when replacing a worn Ford Design seal with the correct dimensions.

Installation Notes and Tips

Verify the vehicle’s steering gear design and compare the seal dimensions before installation. Clean the housing bore and shaft area thoroughly so the new seal seats evenly. Inspect the shaft surface for scoring or corrosion, since damage in the sealing area can shorten seal life. Confirm application details for the exact model year and Ford Design requirement before ordering.
