If the wheel is not too tight, you can get it off easily. Remove the horn rod. Loosen the steering wheel nut so its flush with the top of the threads. Pull on the steering wheel while striking the nut with a hammer. If the wheel is loose, this will get it loose enough to remove. Do not strike so hard you ruin the threaded portion of the column. It is delicate. If the wheel is not free enough to do it this way, use a steering wheel puller with liberal amounts of good penetrating oil, and often time, as in let it soak a day or two.. You can get one from most A suppliers. You do not have to remove the column from the car.
