You don't need the tool in my experience.

Try this:

1) jack up the car
2) hit a spinner ear with a lead hammer in the 'loosen' direction with a mild amount of force
3) turn the wheel
4) hit the next spinner ear
5) repeat 3 & 4

It may look like you aren't getting anywhere, but in a minute or two it will loosen. Spin-tink-spin-tink-spin-tink. Just keep at it, and boom it's off.

You don't need to hit them hard, pretty much the weight of the hammer is what does it. I don't think this is possible to do WITHOUT a lead hammer; make sure you have one.
