It's easier with the wheel removed. Airbag pyrotechnics need to be disabled first for this and evaporator replacement assuming you have passenger side airbag also
To disable the airbag follow these instructions:

1. Turn off the ignition switch and remove the key
2. Remove the negative battery from the battery and tape it or wire it away from the battery
3. Remove the front passenger side floor mat, carpet and plastic panel on the floor
4. Disconnect the red plug

There are 2 torx head screws (they may be security head torx) affixing the airbag to the steering wheel from behind. You will need a long allen wrench style torx wrench to reach the bolts from the access holes on the backside of the steering wheel. Once loosened the airbag pulls off from the front. Store the air bag in a secure location on a horizontal surface with the airbag side pointing upward (aluminum back down). Follow the links below for steering wheel removal and pod replacement. Good luck, Mark
