Detailed Description

This Dorman steering knuckle kit is built for 2013-2022 Buick Encore and 2013-2022 Chevrolet Trax front left repairs. Part number 686-423 is engineered to reduce the labor and equipment normally associated with wheel bearing service by supplying the critical components already assembled. For shops and DIY repairs alike, that means less disassembly and a more straightforward installation path on the Buick Encore and Chevrolet Trax front left corner.

The assembly uses an iron knuckle with a 105 mm bolt circle diameter, 136 mm brake pilot diameter, 54 mm hub pilot diameter, and 73 mm inside diameter. It is configured for driven applications and uses an encoder-type ABS setup. This part cross-references 13543432 for the same application.

What It Helps Repair

• Wheel bearing noise from a worn front left bearing assembly
• ABS warning concerns related to the encoder-equipped wheel-end assembly
• Excessive play or looseness at the front left knuckle and hub area
• Time-consuming press work during steering knuckle and bearing service
• Damage to the dust shield or hub-related wheel-end components

Installation Notes and Tips

Verify front left fitment before installation. Fits 2013-2022 Buick Encore, front left, and fits 2013-2022 Chevrolet Trax, front left. Confirm ABS encoder orientation, brake pilot dimensions, and wheel-end hardware alignment during service. Because this assembly is loaded, it can reduce the need for separate bearing press work, but proper torque procedures and final inspection remain essential.

Quality Assurance

Dorman OE FIX parts are built to streamline repairs by combining critical service components into a single assembly. Part number 686-423 follows a standard replacement format for direct wheel-end service on the listed Buick Encore and Chevrolet Trax applications.
