use a pitman arm puller to pop the lower ball joint out.

i used this, ripped the first boot I used because I didn't know how to use it, but got it right for the next time i used it. You will need some sort of small metal plate as the end of the puller that pushes is pointed and will ruin the end of the ball joint unless you have something to spread the force (a small metal plate w/ a hole in it).
