Steering Knuckle Seal for Front Axle Service
InMotion WS204005 is a nitrile steering knuckle seal built to help keep contaminants out of the sealed area around the front axle assembly. With a 1.784 in. outside diameter, 1 in. shaft diameter, and 1.78 in. housing bore, it is sized for specific Spicer 44 and Spicer 30 front axle applications found on classic Ford, Chevrolet, and GMC trucks and SUVs.
Use WS204005 when servicing a front axle that needs a precise sealing surface to help reduce fluid loss and protect internal components from dirt and moisture. This seal is a direct-fit service part for a wide range of vintage 4x4 platforms, including Ford Bronco, Ford F-100, and Chevrolet K10 applications.

Detailed Description
InMotion WS204005 is engineered as a steering knuckle seal for front axle use on select Chevrolet, Ford, and GMC vehicles equipped with Spicer axle assemblies. It helps maintain a secure barrier at the sealing point, limiting the entry of debris and moisture while supporting proper retention of lubricants in the axle area. For restorations and maintenance on a Ford F-250, Ford F-350, or Chevrolet Blazer, this seal provides the dimensional accuracy needed for service work on older driveline systems. Part number WS204005 is also a practical reference when sourcing a replacement seal for Spicer 44 and Spicer 30 front axle configurations.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Front axle fluid seepage at the seal interface
- Contamination from road debris, dust, and moisture
- Wear caused by compromised sealing surfaces
- Service issues on aging Spicer axle assemblies
- Seal replacement needs during front axle maintenance
Installation Notes and Tips
- Verify axle type before ordering; fitment varies by Spicer 44 and Spicer 30 configurations.
- Inspect the shaft and housing bore for scoring, corrosion, or distortion before installation.
- Clean the sealing surfaces thoroughly to promote proper seating.
- Confirm dimensions against the removed seal when servicing older Ford, Chevrolet, or GMC front axles.
- Use the vehicle notes to match the correct front axle application.
Quality Assurance
InMotion manufactures this seal with precision-focused construction and high-quality materials for front axle service. The nitrile sealing material is selected for durability in demanding driveline environments.
