Control arms typically link the steering knuckle to the chassis and provide a pivot point between the suspension and body frame. Depending on the configuration of your suspension, whether multi-link, MacPherson or double wishbone, control arms can be located in both the upper and lower position on the front and rear suspension.

Control arms feature ball joints and bushings, which work together to maintain wheel position and correct tracking, including the lateral and longitudinal positions of your wheels while in motion. They must resist multiple loading forces, such as acceleration, braking and cornering forces, while also carrying the suspended body weight of your vehicle. Tasked with maintaining dynamic wheel alignment, control arms provide resistance to unwanted suspension movement and reduce noise and vibration.”
