Usually, these ball joints have been made up of a socket and a bearing stud that is fitted inside a lubricated casing. Their purpose is to act as pivotal connectors between the suspension system and the wheels of your vehicle.
The squeaky noise is the common sign that shows the ball joints are wearing out. It may also show that the joints are rubbing up against your vehicle’s wheels. This noise may come when you are passing over the bumps, drifting, or taking corners.
