What Are Control Arms?
The suspension system in your car is the connection of your wheels, springs, shock absorbers, and other car parts which maximize contact between your tires and the road. A control arm, also sometimes referred to as an A-arm, is a fundamental aspect of your suspension system, connecting your car frame to the front wheel hubs.
Suspension components known as bushings and ball joints can be found on either end of a control arm. The primary function of the control arm is to guide the car's wheels up and down on the road and control proper steering.
How Do Control Arms Work?
The bushings that are connected to the control arms are flexible and cause the control arms to swing upwards and downwards when driving on rough terrain and other road surfaces so the car can stay on the road. A swivelling ball joint connected to the control arm enables the car to be turned in a specific direction.
