Or you can go to your local auto parts store as many carry the Lisle tool to clamp them but it is around $30. As far as taking the axle out, it's easy. Clean it up and regrease it before you put it back on. If you've never taken a CV apart watch it on youtube and hopefully one of the videos where someone uses a hard plastic or brass mallet to not damage it with a regular hammer.
