The ball joint, also known as the ball head, is an important element that makes up a car and actually plays the role of a "joint". It achieves power transmission between different axes through spherical connections and provides multi-directional rotation function, which can ensure smooth operation of the steering mechanism and effectively reduce vibration. The ball joint is an indispensable component in the joint area of the connecting rod suspension and balance bar, mainly responsible for transmitting the force of the suspension and balance bar. Even if the left and right wheels encounter bumps or holes on the same road surface during driving, the balance bar will not function.

However, when the left and right wheels pass through different road surfaces and form bumps or holes, that is to say, when there is a difference in the horizontal height of the left and right wheels, axial torque will be generated to suppress the rolling of the vehicle body. The stabilizer bar only makes the driving feel harder when it is in effect. It does not increase the overall hardness of the vehicle like a hard spring, but relies on the spring to reduce the body roll.

Once the ball joint of the car malfunctions, it will be noticeable that the vehicle is swaying left and right while driving, which can make it difficult to control. Deviation from the normal driving trajectory may lead to traffic accidents, thereby threatening people's lives and property safety. After the ball head is damaged, the shaking of the wheels during driving can significantly affect the driver's experience, and in severe cases may even cause traffic accidents. This phenomenon is particularly evident when driving at low speeds. Therefore, as a key component of automobiles, ball joints need to be regularly inspected and replaced. Once any abnormality is found in the ball head, it should be repaired or replaced immediately to ensure driving safety.The image is from the internet.
