Dorman 686-453 Front Left Knuckle 15-20 Kia Optima Hyundai Sonata 51715C1000

When an original equipment wheel hub assembly is due for replacement on certain Kia Optima 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 Dorman OE FIX steering knuckle 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.

• Improved design - this steering knuckle has a proprietary coating that helps prevent rust forming between surfaces, providing a more permanent and reliable repair than the OE knuckle design
• Direct replacement - engineered to match the performance of the original equipment steering knuckle
• Location-specific - designed for the front left side of specified Kia Optima vehicles
• Trustworthy quality - backed by a team of product experts in the United States and more than a century of automotive experience
