The control arm is usually located between the wheel and the car body, and it is a safety component related to the driver that transmits force, reduces vibration transmission, and controls the direction. Car chassis suspension is roughly divided into front suspension and rear suspension. Both front and rear suspensions have control arms to connect the wheels and the body. The control arms are usually located between the wheels and the body. The role of the guide control arm is to connect the wheel and the frame, transmit force, reduce vibration transmission, and control the direction. It is a safety component involving the driver.

   The car control arm is the guide and support of the suspension, and its deformation affects the wheel alignment and reduces the driving stability. If there is a problem with the front control arm, the feeling is that the steering wheel will shake, and it is easy to go off track after letting go of the steering wheel, and it is difficult to grasp the direction at high speed. If the above phenomena are not obvious, it is not necessary to replace it, but only need to redo the 4-wheel alignment to stabilize the direction.

    The car control arm is the connecting mechanism between the frame and the wheel. The frame of the bicycle is hard-linked to the wheels, and it will be very bumpy when riding on rough roads, making people uncomfortable. The control arm of the car is made of soft links, and a shock absorption mechanism is added. We will not feel too uncomfortable when we sit in the car on uneven roads. , and the handling stability of the car is also much better.
