Installing The Upper Ball Joint
SPECIAL TOOLS REQUIRED (or equivalents)
^
J-23742, Ball joint separator.
REMOVE OR DISCONNECT
1. Raise the vehicle and support the lower control arm with floor stands. Since the weight of the vehicle is used to relieve the spring tension on the
upper control arm, the floor stands must be positioned between the spring seats and the lower control arm ball joints for maximum leverage.
WARNING: Floor jack or stand must remain under the control arm spring seat during removal and installation to retain the spring and
control arm in position. Failure to do so could result in personal injury.
2. Wheel and tire assembly.
3. Caliper and support caliper with a piece of wire to prevent damage to the brake line.
4. Cotter pin (68) and stud nut (67) from the upper ball joint (66).
5. Using J-23742, apply pressure on the tool until the stud breaks loose from control arm.
6. J-23742 and pull the stud away from the knuckle. Support the knuckle assembly so that its weight will not damage the brake hose.
