disconnect battery, Undo two screws either side of the pillars on the steering wheel, gently lever the airbag off, keeping your head to one side of the wheel, there is a actvation cord underneath it which just plugs onto the wheel, pop that off and put if somewhere, where it will not become static thus allowing it to gain charge. Once that is off then the steering wheel should pop off once a big 19mm nut has been removed from the column.
