The Harbor Freight tool works fine if you grind a relief in the middle sized tube so that it fits on the bottom. You will need to use another custom bit (we used three shaft collars we had lying around) to press the ball joint out. It will press in nicely using the smaller tube on top and just the adapter on the bottom. You may want to "assist" with a hammer as it won't pull quite straight.

A press will work very nicely, but you will need an internal spring compressor to remove the control arm safely.
