You need a ball joint press tool, the ford hub nut tool, and a torque wrench - you can rent both.
Take the locking hub assy off, then brakes, then the special bearing nut off, slide the rotor off.
Take the spindle off (6 bolts) and the dust shield.
Take the axle shaft out (the passenger side is 2 pieces, DO NOT remove the passenger side mid shaft from the differential, cut the boot clamp and separate)
Remove tie rod end from steering knuckle, then ball joint nuts.
Index or otherwise mark the camber adjuster on the upper ball joint shaft (imperative this piece goes back in the way it came out)
Hammer out the steering knuckle by hitting the ball joints.
Replace ball joints.
Replace grease seal on the back of hub/rotor assy.
Torque new ball joint nuts to spec.
When the lower ball joint shaft spins, use a jack or c-clamp to force the ball joint up to the axle beam.

Put it back together.
6 hours tops.
Buy a Haynes manual!!!
