Help keep the front end feeling composed and predictable with this Dorman control arm, part number 520-231, a front left lower assembly built as a direct replacement for the original equipment on the 2000-2004 Ford Focus. It arrives with the ball joint and bushings already installed, so it goes in as one unit and saves time and labor.
A lower control arm connects the wheel assembly to the chassis and pivots on its bushings as the suspension moves. The ball joint lets the steering knuckle turn and travel.
- Direct replacement: Designed to take the place of the original assembly on the listed applications.
- Ready to install: Each assembly includes a pre-installed ball joint and bushings, which cuts down on installation labor.
- Tested for ride quality: Put through Dorman's industry-leading evaluation process, intended to deliver a smooth ride, directional stability and predictable dynamics.
- Corrosion protection: Additional coatings help resist rust and corrosion.
Signs this part may need replacing include clunking over bumps, loose or wandering steering, uneven tire wear and vibration felt through the steering wheel. Inspect the suspension to confirm the cause before ordering. If a worn control arm on your 2000-2004 Ford Focus is behind those symptoms, this Dorman suspension control arm and ball joint assembly replaces it. This listing is for one front left lower assembly, and we recommend replacing both sides together for balanced handling. See the "Vehicles it fits" section for engine-specific details.
