i removed mine last week.
take terminals of battery and leave for about 30 mins.
loosen the 2 screws holding the airbag in place on either side of the wheel
undo these screws and the airbag will come out (store it somewere safe)
then unclip all the connections
next loosen the nut that holds the steering wheel on
fight with the wheel until it decides to come off
thats all i did to change the steering wheel in the car
fairly straightforward.
