Hello, Newcomer here.
I have a 2005 Trailblazer LT EXT ~170K miles with some play in the steering wheel.

I don't hear any noises while turning the wheel, there also isnt any major drift while driving, certainly not enough for me to really notice. I checked ball joints, bushings, tie rods and steering rack bushings, all checked out. Shocks and struts are about 2 months old at this point, alignment was performed after replacement with no issues reported by the shop. Tires also in good ccondition.

I held onto the steering shaft that's accessible from behind the gas pedal with a pair of vice grips and wiggled the wheel at the same time. I could not detect anything wrong so it's gotta be down below.

I took a look underneath, moving the boot upwards on the lower U joint to take a look, now this is my first time doing anything with steering components, but the U joint didn't seem loose to me. I also had someone move the steering wheel while I was down there, there weren't any noises.

So that would just leave the gears in the steering rack as the main culprit, or have I missed something? I also have some videos when I had it up on the jack showing the play and the sort of springyness of the wheel when jiggled around. I'll get those uploaded as soon as I can.
 
I have the exact same thing. About an inch of steering wheel play that feels like there's nothing. This is a fairly new rack and pinion too. I think it might be the pinion bearing play adjustment. Did find this over at the TBSS forum:


And also found this Reddit thread with a picture:


The next time I have mine up on ramps, I'll give this a try.

Thanks, I'll try the adjustment later this week when I have time and report back.
Edit to this post: I watched a YT video on doing a preload adjustment, some of the comments are saying to have the wheels turned all the way to one direction while you do this.

Here's the videos I mentioned, I'm not sure how well it'll come across in them but you can see the steering wheel sort of bounce a bit. And in the first two the vehicle is off the ground, in the third its back on the ground and you can see the amount of rotation I'm able to make.
