Steering Gear Seal Overview
InMotion WS240151 is a steering gear sector shaft seal built with nitrile sealing material for a tight barrier against contaminants and fluid loss. It is a fitment-based replacement for classic Ford, Lincoln, and Mercury applications with manual steering or UniSteer power steering, depending on the vehicle.
Key Features
- Nitrile construction for dependable sealing performance.
- Inside diameter of 1.125 in. with a 1.5609999999999999 in. housing bore.
- 0.187 in. thickness and 1.572 in. outside diameter for precise fitment.
- Helps keep debris and moisture out of sensitive steering components.
- Built for steering gear sealing service in vintage applications.
Detailed Description
This InMotion steering gear sector shaft seal is engineered to maintain a secure seal where the shaft passes through the steering gear housing. The nitrile sealing material is selected for sealing durability, while the dimensional specifications help support a proper fit in the intended housing bore and shaft diameter. WS240151 is a practical replacement for restoring sealing integrity in older steering systems, including Ford F-100, F-250, F-350, Thunderbird, Lincoln Continental, and Mercury Colony Park, Marauder, and Villager applications listed below. This part number, WS240151, is also useful when matching an OE-style seal by dimensions and application.
What It Helps Address
- Steering gear fluid seepage at the sector shaft.
- Contamination entering the steering gear housing.
- Wear-related sealing loss in aging steering systems.
- Moisture intrusion that can affect internal components.
- Fitment issues when replacing a worn sector shaft seal.
Installation Notes and Tips
Verify shaft diameter, housing bore, and seal thickness before installation. Clean the sealing surface and housing thoroughly so the new seal seats evenly. Confirm the vehicle uses the listed steering configuration, since fitment varies by manual steering and UniSteer power steering applications. For reference, WS240151 fits 1955-1956 Ford Thunderbird, N/A with Manual Steering; fits 1959 Ford F-100, N/A with Manual Steering; and fits 1958-1964 Lincoln Continental, N/A with UniSteer Power Steering.
Quality Assurance
InMotion uses precision manufacturing and high-quality materials to support reliable sealing performance in demanding steering service. WS240151 is built to provide a secure barrier that helps protect internal components and extend steering system service life.
