The function of the vehicle control arm, also known as an A-arm or wishbone, is to connect the steering knuckle to the vehicle's chassis or frame. This crucial component plays a pivotal role in controlling the movement of the wheels, particularly during steering and suspension compression. By providing support and stability, the control arm helps maintain proper wheel alignment, ensuring optimal tire contact with the road surface for enhanced traction and handling. Additionally, the control arm absorbs and distributes forces generated by road irregularities, contributing to a smoother and more comfortable ride. Proper maintenance and inspection of control arms are essential to ensure safe and reliable vehicle operation.
