When an original equipment wheel hub assembly is due for replacement on certain Ford Explorer SUVs and Police Interceptor Utility vehicles, 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 loaded Dorman OE FIX steering knuckle offers the labor-saving convenience of being pre-assembled and features a patent pending and proprietary coating that helps prevent corrosion between surfaces, providing a more permanent and reliable repair than the factory knuckle design. This kit includes all the needed components already assembled for a fast, simple, safe installation. It includes a new rear left side knuckle, wheel bearing, hub and application-specific hardware.
