Ball Joint: Testing and Inspection
INSPECTION
Ball joints must be replaced if any looseness is detected in the joint or the ball joint seal is cut.
To inspect the ball joints, raise the front of vehicle allowing front suspension to hang free. Grasp the tire at the top and bottom and move the top of
tire in an in-and-out motion. Observe for any horizontal movement of the steering knuckle relative to the front lower control arm. If the ball stud is
disconnected from the steering knuckle and any looseness is detected, or if the ball stud can be twisted in its socket using finger pressure, replace
the ball joint.
Ball stud tightness in the steering knuckle boss should also be checked when inspecting the ball joint. This may be done by shaking the wheel and
feeling for movement of the stud end or castellated nut at the knuckle boss. Checking the fastener torque at the castellated nut is an alternative
method of inspecting for wear - a loose nut can indicate a bent stud or an "opened-up" hole in the knuckle boss. Worn or damaged ball joints and
knuckles must be replaced.
