Chris:
The FSM for the 04 gives what appears to be the ssame instructions for removing the cover (airbag).
They both indaicate screws that are removed from the underside of the wheel.
"(1) Disconnect and isolate the battery negative
cable. Wait two minutes for the system capacitor to
discharge before further service.
(2) From the underside of the steering wheel,
remove the two screws that secure the driver airbag
to the steering wheel armature (Fig. 23).
(3) Pull the driver airbag away from the steering
wheel far enough to access the three electrical connections
on the back of the airbag housing (Fig. 24).
(4) Disconnect the steering wheel wire harness
connector for the horn switch from the horn switch
feed pigtail wire connector, which is located on the
back of the driver airbag housing
(5) The clockspring driver airbag pigtail wire connectors
are secured by integral latches to the airbag
inflator connector receptacles, which are located on
the back of the driver airbag housing. Depress the
latches on each side of the connector insulator and
pull the insulators straight out from the airbag inflator
to disconnect them from the connector receptacles.
(6) Remove the driver airbag from the steering
wheel"
Don't know what else to tell you.
