1986 Chevy Astro trying tighten sterring column

Do you mean your tilt wheel is loose? If you pull out the turn signal switch a little you should be able to get too two of them, other wise you need a pin puller to remove it down to the screws, the 2 pins are on the side

If you buy a complete sterring wheel puller it should come with it

that little pin puller breaks easy, thoes pins are tuff sometimes

to get at it you have to have a spring compressor (also in the complete kit ) there is a snap ring that holds it down, then you can pull out everything. First pull the wheel then use the compressor to get at the snap ring set everything in order as you take it out, to get the turn signal switch out you need to go under dash to unplug it and remove the 3 screws and for the turn lever it just pushes in and turns to pull it out ( dont break it), then the ign switch use a pair of needle nose plyers to pull it out the key buzzer, then looking in the same place as the buzzer theres a little hole with a tab, push it up and the key switch should come out its also hard sometimes, remove the plastic cowl then you can see on the side the 2 pins that need taken out to get at all 3 screws sorry right now I can't get you a pic, if you can get a hold of razamataz he might do it for you

No prob, here to try and help if we can
