A front control arm is a suspension component in an automobile that connects the steering knuckle or spindle to the vehicle's frame or body. It helps to control the position of the wheel and steering movement of the vehicle. It also helps in absorbing road shock and vibrations. The control arm typically has a ball joint at each end, which allows for a range of movement as the suspension travels up and down. It is a critical component in maintaining the stability and handling of the vehicle.

The front control arm, also known as a wishbone or A-arm, is a suspension component in an automobile that connects the steering knuckle to the frame of the vehicle. Its main function is to allow the wheel to move up and down with the suspension while also allowing the wheel to pivot left and right for steering. The front control arm typically consists of two separate parts: the upper arm and the lower arm. The upper arm is connected to the frame of the vehicle, while the lower arm is connected to the steering knuckle. Together, these two parts form an A-shape, which is why it is called an A-arm. The control arm works by absorbing the shocks and vibrations caused by the road surface and transmitting them to the frame of the vehicle, which helps to provide a smooth ride for the passengers.
