The control arms are the main components of the suspensions. There is a connection between the front wheel and the frame, and at times each wheel can have up to two arms. The amount of control arms a vehicle has depends on the cars suspension. They are also designed to help the wheel go over bumps with ease.
Chassis functionThe chassis is the end of a control arm which is connected to a bushing. It controls the position and maintains distance from the inboard mount. The bushing alone does not control the movement of the arm because a separate component constrains it.
Importance of the control armsThe importance of the control arms is that it allows the control arm to maneuver around the vehicle. The control arm is prone to wearing out, when that happens the arm can cause pulling and a poor driving experience. The control arm is part of the MacPherson strut and has a spring.
