OE FIX Steering Knuckle for Kia Sorento
Dorman 686-451 is a front left steering knuckle for select 2016-2018 Kia Sorento SUVs. It addresses a common service problem where corrosion can seize the wheel hub bearing to the steering knuckle, making the original knuckle difficult to reuse.
Built as a standard replacement from cast iron, this Dorman OE FIX knuckle uses a proprietary corrosion-resistant coating on the mating surfaces to help reduce rust buildup between the knuckle and hub assembly. For Kia Sorento front left steering knuckle replacement jobs, 686-451 provides a more serviceable repair path than the factory design.
Key Features
- Fits 2016-2018 Kia Sorento, front left
- Dorman OE FIX design for corrosion-prone hub-to-knuckle interfaces
- Patent-pending coating helps reduce rust between contacting surfaces
- Cast iron construction for standard replacement service
- Black natural finish
- Includes the bare knuckle, cotter pin, bolt, and nut listed in the package contents
- Cross-references Kia 51715C5300 for the same application
Detailed Description
When the wheel hub bearing and steering knuckle seize together from corrosion, the repair can become time-consuming and may require replacing the knuckle instead of salvaging it. Dorman 686-451 is engineered for that exact problem on select Kia Sorento models, using a coated surface treatment that helps limit corrosion where the hub and knuckle meet. This makes it a practical choice for front left steering knuckle replacement on 2016, 2017, and 2018 Kia Sorento SUVs.
The knuckle is cast iron and built as a standard replacement part with the required sensor hole and caliper mounting provisions. If you are servicing a Kia Sorento front left steering knuckle and hub area, 686-451 is designed to restore the steering and wheel-end mounting point while addressing the corrosion issue that often affects the original part.
What It Helps Fix
- Seized wheel hub bearing and steering knuckle surfaces
- Rust buildup between the hub and knuckle
- Knuckles that cannot be reused after hub removal
- Corrosion-related steering knuckle replacement on Kia Sorento SUVs
- Front left wheel-end service issues on affected vehicles
Installation Notes and Tips
Verify front left fitment before installation on 2016-2018 Kia Sorento models. Inspect the wheel hub bearing, caliper mounting points, and sensor opening during service, and replace any worn or corroded related components as needed. Because this part is a bare knuckle, transfer or service the applicable suspension and brake components according to the vehicle repair procedure.
Quality Assurance
Dorman OE FIX parts are developed to address known failure points in original designs. Part number 686-451 is built as a direct replacement steering knuckle for the listed Kia Sorento applications, with a corrosion-resistant coating intended to improve long-term serviceability at the hub-to-knuckle interface.
