The Replacement RT28080046 is a front left (driver side) steering knuckle assembly engineered as a direct OEM replacement for AWD Toyota Highlander models. Manufactured to meet original equipment specifications, this knuckle restores proper front suspension geometry and steering function.

The steering knuckle is a critical front suspension component that houses the wheel hub and bearing assembly, and serves as the pivot point connecting the suspension and steering systems. It interfaces with the upper and lower control arms via ball joints and links to the steering rack through the tie rod end, allowing the front wheels to steer, spin, and travel over road imperfections.
