  Control Arm Build Quality


control arm    


The automobile's control arm or wishbone is a nearly flat and roughly triangular suspension component (or sub-frame), that pivots in two places. The broad end of the triangle attaches at the frame and pivots on a bushing. The narrow end attaches to the steering knuckle and pivots on a ball joint. The upper control arm can clearly be seen at the top portion of the suspension components. The roughly A-shaped design with the top of the A near the tire and the bottom two points connected to the frame inside the body's space. Two such devices per wheel make up a double wishbone suspension, while one control arm per wheel makes up a part, usually the lower part, of a MacPherson strut suspension or of various other configurations.


The primary function of the control arm is to attach the wheels to the frame of the vehicle. There are many other components that keep the wheels connected to your car, but the control arm adds a level of stability. When you are driving over bumps in the road, or through other rough driving conditions, the control arm allows the wheels to move up and down, while stabilizing the frame of your car. This is important because it means that the wheels absorb the bumps and move freely, so that you do not feel every single bump in the road that you drive over.


Over time, your control arms will begin to wear down. There is no way to prevent this from happening. You can increase the longevity of your control arm and suspension system with routine maintenance, but eventually you will have to replace your control arms to restore stability. When your control arms begin to wear down, there will be excessive play in your suspension. This will make controlling the car move difficult and will also reduce the dampening effect. If your car’s suspension is not performing like it used to, it is a good idea to have your control arms inspected.
