TOYOTA Control Arm Bolt

The control arm connects the wheel to the vehicle body elastically through ball joints or bushings, forming a flexible guide and load-transmitting bridge. This design not only allows the wheel to move freely relative to the vehicle body but also enables precise control over the wheel's position during driving. When the wheel is subjected to external forces (such as bumps, braking, or steering), the control arm transmits these forces to the vehicle body while adjusting the wheel's trajectory through the suspension system to ensure stability under complex road conditions
