OK, after quite a bit of effort I got the airbag off and lower panels and was able to get a good look at how the steering
wheel is attached and the internal attachments of the power adjustable steering column.
First, how to remove the panels. There's one main panel you want removed below the steering
wheel attached with 4 screws and a lot of clips. The first screw you need to get to is very low down, outside the normal line of sight on the right. It's the only one there, can't miss it. The other 3 are behind the panel on the left end of the dash. That panel is just clipped on but it's also held in by the weather stripping and, while you could work around it, it's easiest to just pull the weather stripping free around the panel. You should be able to see the screws to be removed after that end piece is gone. The rest of the main panel under the dash just unclips. Good luck with that part. Then you might want to remove the piece under the steering
wheel. There are 3 screws here, one obvious and 2 hidden. First you need to unclip the top section from the bottom around the steering column. It just snaps off with a little bit of prying. Note that the top is the inside piece so apply pressure appropriately. Now, with the top up out of the way, rotate the steering
wheel 90°. You should be able to find a screw on one side. Remove that, turn the
wheel again, and take off the other one. Now you can take off the obvious screw that was at the bottom of that panel and it more or less should fall off.
Now on to the airbag. After disconnecting the battery there are 3 clips you need to move to get the airbag free. They are at 3, 6, and 9. They are all accessed through small holes in the back of the steering
wheel.
You need to do the 6 O'clock one first at the bottom of the steering
wheel. For this, I found that what works best is a Robertson screwdriver that barely fits in the hole (in my case a #6 - green). If you put it in about as straight up as you can with the handle away from you a bit you'll hit a lip. Move the handle toward you a little and you'll move ahead a bit further to the plastic piece that has to be pushed in. Push pretty hard and the airbag will come free at the bottom.
For 3 and 9 O'Clock clips you'll need a different screwdriver. The best would be something about 3" shaft or more, flathead, that fits in the hole with a slim handle. You don't want it to be so long that it's hung up on the bottom of the gauge cluster. Rotate the steering
wheel 90°. If you look at the back of what is now the top part of the steering
wheel, very close to the steering column, you'll see a few square or rectangular holes. The longest one is your target. Take your screwdriver (or similar device) and put it in that longest hole as close the the steering column as possible and as parallel to it as possible as well (keep the handle close to the steering column, thus the slim handle). When it stops you're likely at the spring. You want to move the tip of the screwdriver up a bit so that you feel it slip past the spring. Now, you can pull the handle of the screwdriver up, levering the spring down. This should allow you to pull out that side. Do the same for the other side.
One thing I found helped was not have the already released side too far out while trying to get out the unreleased side.
So here's what I found. The steering column attachments all seemed perfectly fine and tight. I didn't see a bracket that could be easily damaged by someone pushing on it hard. And, it was very clear at this point that the movement I was getting was where the steering
wheel itself was attached to the column. The bolt felt tight and tightening it further didn't fix anything. So, off it came. And then I saw the problem. The
wheel was very loose on the splined shaft. Either the shaft,
wheel, or both were either very worn or defective on installation. I've never seen a
wheel that so easily rocked back and forth on the shaft. I was hoping that maybe a washer would cinch things down a bit better but the
wheel has a built in one and it wasn't bottomed out at all. So, I put the bolt back in and tried to crank it as tight as I could. I couldn't get rid of all of the movement but it was a bit better. The
wheel is still rocking, just a bit, because it's loose on the shaft in the first place.
So, not totally successful. But, at least I know the
wheel isn't falling off any time soon.
