This Dorman suspension control arm is designed to replace the original equipment on the listed applications. Dorman puts it through an industry-leading evaluation process aimed at a smooth ride, directional stability and predictable dynamics.
- Trustworthy replacement: takes the place of the original assembly on the listed applications.
- Complete repair: arrives with the ball joint and bushings pre-installed, saving time and labor.
- Quality engineering: underwent industry-leading testing intended to deliver a smooth, stable and safe ride.
- Durably designed: additional coatings provide rust and corrosion resistance.
The lower control arm links the wheel assembly to the chassis, and its ball joint lets the knuckle pivot as the suspension moves and the wheel steers. Signs this part may need replacing include clunking over bumps, loose or wandering steering, and uneven tire wear. Diagnose the cause before replacing, because other suspension parts can produce the same symptoms. It is sold individually for the front left lower forward position, and replacing both sides together is recommended.
