Dorman - OE Solutions Suspension Control Arm P/N:520-385
Help keep the front right wheel properly located and tracking with the Dorman control arm 520-404, a front right lower arm built as a direct replacement for the 1999-2003 Lexus RX300. This Dorman lower control arm is precision-engineered and rigorously tested to serve as a dependable replacement for the original equipment.
As a Dorman suspension control arm, it links the steering knuckle to the vehicle's chassis, letting the wheel move up and down with the suspension while holding it in position. Signs a control arm may need replacing include clunking over bumps, loose or wandering steering, uneven tire wear, and a cracked or bent arm. Have the suspension inspected to confirm the cause before replacing. Full application details are in the Buyer's Guide tab.
