HI Guys,
Pulling off the steering wheel is fairly easy, from memory
1. Disconnect the Battery (and wait a minute) - neutralises the airbag circuit
2. On the back of the steering wheel is 4 clips that hold on the airbag, you'll need a small screwdriver to release them
3. Remove the airbag connector - just pulls off from memory
4. Remove the stereo buttons
5. Undo the centre nut but leave it on a turn and give the wheel a yank, should cone loose, then remove the nut and off she comes, be careful when reinstalling the new wheel as the wiring goes into a clock spring and if you put it in wrong it will break and you'll get an airbag code. It has a green (I think) window to tell you its in the right place.
Note: When removing the airbag be very careful not to have anything in your mouth etc as if it accidently deploys, it will kill you, chances are pretty slim though
