How to Remove the Ball Joints on a Car

Ball joints are spherical shaped balls which connect arms of the control arm with the steering knuckles. They are based on the ball and socket design present in human hip, and are used in almost every automobile out there.

Ball joint is made up of two parts; a bearing stud; and socket enclosed in a container. Both these parts are made up of steel or metal alloy. Damaged or worn out ball joints cause the suspension of the vehicle to go haywire. This is why experts recommend inspecting ball joints regularly and keeping them properly lubricated.
