Description

Keep the front right wheel hub mounting solid with the Dorman - OE Solutions Steering Knuckle 686-340, a direct-fit replacement engineered for the front right side of the 2015-2023 Lexus GX460 and 2015-2024 Toyota 4Runner. On certain Lexus and Toyota SUVs, rust can build between the steering knuckle and the wheel hub bearing until the two seize together, making the original knuckle difficult or impossible to salvage during a hub job — a common issue in Salt Belt regions that can also develop over time under normal use.

Corrosion-fighting design: features a patent-pending, proprietary coating that helps prevent rust from forming between the mating surfaces, for a more permanent and reliable repair than the factory knuckle design.
Direct replacement: engineered to match the performance of the original equipment steering knuckle.
Location-specific: designed for the front right side of the specified Toyota and Lexus vehicles.
Trustworthy quality: backed by a team of product experts in the United States and more than a century of automotive experience.

This is an OE FIX component that addresses the seizing problem at its source. See the "Vehicles it fits" section for the full engine-level application list.
