Dorman 686-407 FRONT LEFT KNUCKLE

When an original equipment wheel hub assembly is due for replacement on certain Ford F-150 trucks, the job can become difficult because rust has grown between the surfaces of the steering knuckle and the wheel hub bearing, ultimately resulting in the two assemblies seizing together. Although this problem is common in Salt Belt regions, it can also occur over time under normal vehicle use and when it does it can make the knuckle challenging or impossible to salvage. This Dorman OE FIX steering knuckle features a patented and proprietary coating that helps prevent corrosion between surfaces, providing a more permanent and reliable repair than the factory knuckle design.
