Wear Inspection Procedure

CAUTION: When raising vehicle by lower control arm using a floor jack, a protective pad must be used on saddle of jack. This is required so control arm does not get nicked, gouged, deformed or damaged in any other way by floor jack.
  1. Position a floor jack under outer end of front lower control arm. Carefully raise vehicle so front wheel and tire assembly is just lightly contacting floor (vehicle weight relieved from tire).
  2. Have a helper grasp tire at top and apply an inward and outward force against top of tire. While inward and outward force is being applied against tire, look for any movement between upper ball joint and steering knuckle.
  3. If any lateral movement is evident at upper ball joint, upper control arm will need to be replaced.
  4. Repeat this procedure on opposite side of vehicle to inspect remaining upper ball joint.
