If you insist on using a cheap ass Harbor freight tool, use a combination of preload and a hammer to shock the knuckle to get the ball joint out.

Here a video on this procedure.

For removing the torx bolts that is securing the ball joint to the spindle, I would recommend that you use a hand impact instead of trying to use a breaker bar with the female torx socket. You don't want to snap the torx bolt off and need to drill out the remaining pieces.
