Ok. Ok. There is a very easy way to do this without special tools:
1) Remove the nut on the ball joint.
2) Replace the same nut, but only tighten one or two turns.
3) Hit the nut with a big hammer so the ball joint drops 1/2", but will still be attached with the nut.
4) Remove nut again. Balljoint should come free. Replace nut.
