Replace a worn upper arm and its ball joint in a single step with the Dorman control arm and ball joint assembly, part number 522-721. Cataloged for the front left upper position, it is designed to directly replace the original assembly on the 2005-2023 Toyota Tacoma. See the Buyer's Guide tab for engine details.
The upper arm connects the steering knuckle to the vehicle's frame. It lets the wheel travel up and down while holding it in position, and the ball joint acts as the pivot that lets the knuckle turn and move. Dorman ran this design through an industry-leading evaluation process aimed at a smooth ride, directional stability and predictable dynamics.
- Direct replacement: built to take the place of the original arm on the listed 2005-2023 Toyota Tacoma applications.
- Complete repair: the ball joint and bushings come pre-installed, which saves time and labor.
- Quality engineering: went through industry-leading testing intended to deliver a smooth, stable and safe ride.
- Durably designed: additional coatings help resist rust and corrosion.
Signs that an A-arm on the 2005-2023 Toyota Tacoma may need replacing include clunking or knocking over bumps, loose or wandering steering, uneven tire wear, and worn bushings. If a worn arm or ball joint is the cause, this assembly replaces both. This arm is for the front left side, and replacing the left and right arms together is recommended. A wheel alignment after installation is also recommended.
