Ball Joint: Specifications
Wear Limit
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 the vehicle allowing front suspension to hang free. Grasp the tire at the top and bottom and move the top of
tire with an in-and-out motion. Observe the ball joint area 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 castlellated nut at the knuckle boss. Checking the castlellated nut fastener tightening specification is an
alternative method of inspecting for wear. A loose nut can indicate a bent stud or an worn bore in the knuckle boss. Worn or damaged ball joints and
knuckles must be replaced.
