Always disconnect the battery and let it sit for a few minutes. Normally for most vehicles you take the air bag off and there's a single bolt holding the wheel. Found these on another forum:
1. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
2. Remove the upper shroud from the steering column.
3. Release the steering column tilt lever and lower the column to its most downward position for easiest driver airbag removal access.
NOTE: It may be helpful to use a small mirror to aid visibility during the initial attempt to remove the driver airbag from the steering wheel.
4. There are three airbag retainer access holes (1) on the instrument panel side of the hub of the steering wheel (2), located at the two o'clock, six o'clock and ten o'clock positions. The steering wheel must be rotated to bring each of these access holes up to the twelve o'clock position of the steering column one at a time for removal access.
5. Insert the short blade (Tip A) of the Driver Airbag Removal Tool (Special Tool #) (1) or the blade of an equivalent prying tool into either of the upper (two o'clock or ten o'clock) access holes (3) of the steering wheel hub rear trim cover (2), being certain to place the blade of the tool on the inboard (steering wheel hub) side of the airbag snap retainer wire loop.
6. Push the handle of the tool downward for the blade to pry the snap retainer wire loop (3) upward far enough to disengage the loop from the hook of the steering wheel armature. At the same time, gently pull the driver airbag (1) away from the steering wheel (2) to prevent the retainer from snapping back into place over the hook once it is disengaged.
7. Repeat Steps 5 and 6 at the other upper (two o'clock or ten o'clock) access hole to disengage the other upper snap retainer wire loop.
8. Repeat Steps 5 and 6 at the lower (six o'clock) access hole to disengage the lower snap retainer wire loop. The lower snap retainer wire loop has a distinctive V-shape and must always be installed onto the six o'clock hook of the steering wheel armature.
