Steering wheel pad?

How can I take the steering wheel pad off and will the Airbag blow if I mess with it? I want to get to the nut that holds the wheel on. I think I have some play in that area. Something definitely is clunking in the upper part of the column.

 

Disconnect the ground and let the capacitors drain a bit before you do any airbag stuff just to be safe.

The pad is removed by a torque screw on each side of the wheel covered with a round plastic cover.

 

Where is the ground and how long does it take the capacitor's to drain? Thanks for the reply

 

i am pretty sure he just means the battery. and i would let it sit overnight personally.
