Ball joints are part of the steering and suspension of most vehicles. A ball joint allows the front suspension to moveup and down and steer back and forth simultaneously. A ball joint consists of a metal ball encased in a metal housing.The two partsmove independently of each other and require regular lubrication. A worn-out ball joint may cause erratic steering and requires separation fromthe suspension control arm for replacement. 1.Set the parking brake and chock the rear wheels. Place a floor jack under thefront frame rail on the side of the vehicle where the ball joint is to beremoved. Loosen the wheel lugs on the wheel one turn with a lug wrench. Raisethe floor jack. Place a jack stand under the frame rail. Finish removing thewheel lugs and the wheel. 2.Remove the cotter pin from the castle nut on the underside of the ball jointto be removed with pliers.
