on wheels so that lower ball joint is in a loaded condition.
To inspect for wear, wipe the grease fitting and nipple
free of dirt and grease as for a grease job. If the round nipple
is flush or inside the cover surface, replace the ball joint.
Ball stud tightness in knuckle boss can be checked by
shaking wheel and observe or feel for movement of stud end
and/or nut at knuckle boss, or by removing cotter pin to
