Take a 1/2 drive Craftsman socket one size smaller than one that will fit over the top of the locking lug. Hammer it onto the lug till it's jammed on there, and then use the ratchet to remove it like normal. Once it's off you can knock the lug out of the socket with a punch or the like from the back. Works like a charm, I've done it many times. I only use Craftsman tools for this jobs like this, that way if I would happen to waste it, Sears will give me a shiny new one, no questions asked.
