Control Arm
A suspension link that connects the wheel hub to the vehicle frame.
The control arm maintains proper wheel geometry and alignment during driving. It pivots up and down with the suspension, guided by bushings and ball joints. Worn bushings cause clunking noises and poor handling. Replacing them restores stability and comfort. Proper torque and alignment are critical during installation. High-performance vehicles use aluminum or forged steel arms for strength and reduced weight. Routine inspection ensures consistent steering and tire life.
