Clean all debris around the hole in the hub and the upper control arm. Drop the new ball joint into the hole in the upper control arm. Make sure that the rubber boot does not get pinched in the control arm hole. Push it down clear through.

Bolt the Ball joint to the hub first and then to the A arm.

Put a small jack under the geared hub and raise it until the new ball joint bolt is through the upper geared hub hole. Hand tighten the slotted nut.

Line up the new ball joint and drop the 4 bolts and washers into the holes. Tighten the bolts to 37 ft-lbs. Tighten the 15/16" bolt to 73 ft-lbs while lining up the slot in the nut with the hole in the bolt. Tighten the nut to line it up; never loosen. Insert a new cotter pin.
