Ball Joint Inspection
Ball joints allow components to rotate and change angle. Ball joints can be separate components, or may be integral parts of components such as control arms. How do ball joints work? Ball joints allow components to rotate and change angle while being held in the correct position relative to other components. Ball joints can be separate components, or may be integral parts of components such as control arms. How can ball joints fail? Ball joints are constructed with a ball attached to one part of the vehicle (such as the red steering knuckle) inside a socket attached to another part (such as the blue lower control arm), with a lining injected between the ball and socket to keep the ball tight. The lining wears out over time, or can be damaged as a result of impacts, such as hitting a kerb or deep pothole. Results of failure Movement in worn ball joints can cause clunking noises when driving and reduce ride comfort. The alignment of the wheels relative to the road can also be affected, which can accelerate tyre wear. In cases of extreme wear, the ball can separate from the socket, resulting in loss of vehicle control. Required Service or Repairs Ball Joints should be inspected regularly and replaced if free play is found.
