If you do this project with any regularity then I highly recommend that you get this tool:
http://www.amazon.com/gp/product/B000F5JMEAIt works perfectly on any retainer of this type, every time.
And I emphatically disagree with the poster saying it was not necessary to drill out the staked spot. Yes, you can gorilla out the retainers, but the burrs on it can and will tear up the soft aluminum of the hub, and put you in a world of misery. It takes 30 careful seconds to drill 3/16 or less down in the staked spots, and then the retainers come out easily without damage, and can be reused.
If you drill, and use the OTC tool or an equivalent (a good homemade is obviously fine) that won't oval or mangle the holes, this is a simple task and you can reuse the parts.
