What is a Control Arm?
Control arms are part of the suspension system. Control arms are used to connect the suspension of the car to the frame. An upper control arm and a lower control arm can be found near each wheel and are arranged to form the letter A. They are connected to the wheels through ball joints and to the frame through bushings.
