Detailed Description

This Dorman OE FIX loaded knuckle is engineered for the front left position on 2016-2021 Honda Civic models. Instead of pressing a worn bearing in and out of the knuckle, the assembly arrives with the critical components already matched and installed. That makes it a straightforward option for Honda Civic front left steering knuckle replacement, wheel bearing service, and hub repair work.

The cast iron knuckle uses a Gen 1 ball bearing, is pre-greased, and includes ABS encoder functionality for vehicles with anti-lock braking systems. Additional fitment-related dimensions include a 26-spline configuration, 84.3 mm inside diameter, 93 mm outside diameter, 76.9 mm hub pilot diameter, and 64 mm wheel pilot diameter. The part number 686-429 is also a useful reference when sourcing the correct loaded knuckle for a 2016-2021 Honda Civic.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Repair

• Wheel bearing noise or rough bearing operation at the front left corner
• Hub and bearing service that would otherwise require a hydraulic press
• ABS-related wheel speed signal issues tied to the encoder-equipped assembly
• Damage to the steering knuckle, hub, or dust shield from wear or corrosion
• Extended service time caused by rebuilding the knuckle separately

Installation Notes and Tips

Verify front left fitment before installation on 2016-2021 Honda Civic applications. Confirm wheel stud pattern, ABS encoder style, and axle interface before removing the original assembly. Because this is a loaded knuckle, it is intended to reduce the need for separate bearing pressing during service. Always follow factory torque specifications and inspect related suspension and brake components during reassembly.

Quality Assurance

Dorman OE FIX parts are built to simplify repairs by combining critical service components into one assembly. Part number 686-429 is a direct-fit replacement for the listed Honda Civic applications and is built as a standard replacement steering knuckle kit.
