Ball Joint Service:





3. Remove the upper ball joint cotter pin and nut.
4. Loosen the lower ball joint nut to the end of the stud.
5. Strike the inside of the knuckle near the upper and lower ball joints to break the knuckle loose from the ball joint studs.
6. Remove the camber adjuster sleeve. Note the orientation of the slot in the camber adjuster. The slot should be installed in the same position during reassembly to maintain alignment. If required, use Pitman Arm Puller T64P-3590-F or equivalent to remove the adjuster from the knuckle.
7. Remove lower ball joint nut.
8. Place knuckle in vise and remove snap ring from bottom ball joint socket if so equipped.

CAUTION: The following torque sequence must be followed exactly when securing the knuckle. Excessive knuckle turning effort may result in reduced steering returnability if this procedure is not followed.

6. Install a new nut on the bottom ball joint stud. Tighten the nut to 54 Nm (40 ft lb).
7. Install a new nut on the top ball joint stud and tighten to 115-136 Nm (85-100 ft lb), then advance nut until castellation aligns with cotter pin hole. Install a new cotter pin.
