Ball joints are pivotal components in a vehicle's suspension system, serving as the connection point between the control arms and the steering knuckles. They enable the suspension to move vertically while allowing the wheels to turn left and right, facilitating smooth and precise steering control. Designed to handle significant stress and movement, ball joints contribute to a stable and comfortable ride by absorbing shocks from the road. Their durability and reliability are crucial for maintaining the overall safety and performance of passenger cars, commercial vehicles, and agricultural machinery.
