The "end" of the ball joint is open along the bottom ridge of your steering knuckle (just underneath where the CV axle mates to your hub). There you can spray generously WD-40 or PB and allow to soak. With a small pipe wrench fastened on the base of the ball joint, try to turn and break it loose. Another application of PB may be necessary. Once loose you should be able to twist and pull the ball joint out of the knuckle.

Good luck.
