Dorman - OE Solutions Steering Knuckle P/N:686-413
Give the front-left wheel a new pivot point between the steering and suspension with the DORMAN steering knuckle, part number 686-417 from Dorman - OE Solutions. This Honda Civic steering knuckle is a direct-fit replacement for the front left position on the 2016-2021 Honda Civic, and Dorman designs it to replace the original knuckle.
A steering knuckle, also called a spindle knuckle, links the suspension to the wheel. It provides mounting points for the wheel hub and brake hardware and pivots so the front wheel can turn with steering input. This one is precision-engineered and thoroughly tested as a replacement for the original knuckle on the listed applications.
If a bent or impact-damaged original knuckle is behind pulling, uneven tire wear or an off-center steering wheel, this Dorman knuckle replaces it. Those symptoms can have other causes, so inspect the suspension and steering before you install a new Civic steering knuckle. Transfer or replace attached components as the service procedure directs, and consult the vehicle service information for the correct fasteners and whether they may be reused. A wheel alignment check is recommended afterward.
