Good luck!!! But I don't think airbags should be handled in personal garages???? JMHO. Would be afraid of one going off while handling or not going off when needed in a wreck. Wait, that sounds like Land Rover airbags. HEHE
Disconnect the battery before you attempt removal. Just to be safe. Other than that there should be a couple screws on the back side of the steering wheel holding the AB in.
