To swap cruise pods you don't have to remove the steering wheel at all.
Start by disconnecting your battery then turning your headlight switch all the way on. Leave it for half an hour to an hour to drain out any voltage that may still be present.
After this time has passed, get a flathead screw driver and pop off the two small covers on the steering wheel, One on each side. Underneath you'll find either 7 or 8mm bolts. Remove these.
Now the airbag will come free and you can then disconnect the plug at the airbag itself.
To replace a pod, use a phillips screwdriver to remove the two screws holding a single pod in place. Next remove the connector. These can be tricky so be patient.
Reinstall your new cruise pod in the reverse order.
Once you're done in there, reconnect the airbag and bolt it back in. Reconnect the battery, being aware that the horn may sound. If it does sound, remove the two airbag bolts and loosen the tension on the bag. Retry and refit as needed until the horn no longer sounds until you manually press the horn button.
If you still want to remove the steering wheel, use a Torx socket on either a 3/8ths or half inch drive breaker bar and take it all the way out. Then rethread the screw a couple of turns. You'll understand why in the minute.
Now some people have luck doing it without a puller. Some don't. I've encountered both. Without a puller, brace your feet to the floor and pull like mad, yanking in all directions. We're keeping the bolt on so when it does come free, the steering wheel won't rearrange your face . If it doesn't come free, a puller will be required.
When reinstalling the wheel, note it will only fit in one direction so you can't really put it on wrong. That being said, it's a good idea to make sure the wheels are straight before removing.
