I took these pics when I changed mine. I know its a little late but maybe they'll help.
I hads to pull a torx wrench apart to get the airbag cover off. There are 3 holes in the back of the wheel but only the center one has a bolt in it. You have to turn the wheel to get to it.

Pull the airbag cover
Thn unplug the airbag. Its the wire w/ the yellow sleeve there.
I didn't take anymore pics but after that it a snap. 1 bolt in the center of the wheel then it just slides off, you don't need a puller. Make sure your wheels are straight, I had to redo mine then just lift up & unplug the clockspring.
BTW these are just some supplemental pics to go w/ what Tony said, he gave the PC way to do it. I'm not going to post a bunch of warnings or whatever just use common sense & if you blow yourself up its your own fault!
