1. Disconnect battery
2. Unbolt airbag from steering wheel, then disconnect wires
3. Once airbag is out of the way, you can unbolt the cruise and the steering
wheel controls, or wait until you remove the wheel
4. Take special gear/wheel puller (this procedure does NOT use run of the mill
steering wheel puller) and place tabs in spots on wheel, then turn bolt
until it pops. Do not use a cheap shit puller, because it WILL bend and you
will play hell trying to get the damn thing to work right.
The service manual would be quite handy, there's a whole section on how to do this. I have the 04, though it doesn't have the CRD in it.
