Ball Joint

Print

Only 1949-65 models are equipped with king pins. 1966-69 models are equipped with ball joints.

INSPECTION



A quick initial inspection can be made with the vehicle on the ground. Grasp the top of the tire and vigorously pull the top of the tire in and out. Test both sides in this manner. If the ball joints are excessively worn, there will be an audible tap as the ball moves around in its socket. Excess play can sometimes be felt through the tire.

A more rigorous test may be performed by jacking the car under the lower torsion arm and inserting a lever under the tire. Lift up gently on the lever so as to pry the tire upward. If the ball joints are worn, the tire will move upward 1 / 8 - 1 / 4 in. or more. If the tire displays excessive movement, have an assistant inspect each joint, as the tire is pryed upward, to determine which ball joint is defective.
