Ball joint definition and meaning
A ball joint is a mechanical part that connects two moving parts of a vehicle. It allows free movement in certain directions while still providing support and stability in other directions. Ball joints are essential for the suspension system of a vehicle and help to keep the wheels in contact with the ground. Without ball joints, a vehicle would not be able to move smoothly over uneven surfaces. Ball joints wear out over time and need to be replaced periodically to maintain a vehicle’s suspension. Symptoms of a failing ball joint include steering problems, uneven tire wear, and noise from the suspension.
