Hello there if what you are talking about is that you stering wheel feel lose, well you will have to lift thr front end so that both wheels are of the ground a ramp may work also, then the way to fix this is to get under the front of the van, you should see the stering colum gear box, you will need a alen key and a adjustible wrench, open up the outer nut enough to tigh the alen bolt, do it a bit at the time until the stering wheel feels tighter, and you done.
You should be able to pull off the horn button in the middle. There might be a wire going from the button to a hole in the steering wheel, just push in and rotate to remove it. There should be a clip that you pry off. You can the use a steering wheel remover to pull off the wheel. The 1994 Chevy Astro EXT van has 4 bolts behind the steering wheel/airbag/horn assembly to remove the horn/airbag assembly.
