Lower ball joints are a loose fit when not connected to steering knuckle and wear may be checked without removing ball stud from steering knuckle. Raise and support vehicle under lower control arms, as close to ball joint as possible. Measure distance between upper tip of ball joint stud and tip of grease fitting mounted to bottom of ball joint. Move vehicle supports to a position under frame, allowing lower control arms to hang free. Again measure distance between ball joint stud and grease fitting. If difference between two measurements exceeds 3/32", replace ball joint assembly.
