When it comes to the smooth and stable ride we enjoy in our vehicles, we have the suspension system to thank. Among its essential components is the often overlooked control arm, responsible for connecting the vehicle's chassis to the wheel hub. Let's shed some more light on this component and what it does, where it's located, and everything else there is to know. Understanding the Control Arm The control arm, also known as an A-arm or wishbone, is a vital part of the suspension system in both front and rear-wheel-drive vehicles. It is a hinged component that links the suspension to the vehicle's frame or subframe on one end and the wheel hub on the other. Suspension Geometry and Stability The control arm is a key player in maintaining proper suspension geometry, which is crucial for stable and predictable handling. It works in tandem with other suspension components to keep the wheels aligned and perpendicular to the road surface, e ... read more
