How do you remove the steering wheel on a 1992 GMC Vandura 2500?

It's pretty easy providing you don't have airbags, just pull off the horn cover, remove the screws and discs for the horn assembly, remove the snap ring and nut on the steering post then you can either use a steering wheel removal kit or use a hammer and tap the wheel off the post. I'd heavily recommend the removal kit, they're not expensive. Also it's a good idea to remove the horn fuse so you don't accidentaly set it off.
