I thought it was a belt squeak I heard last week. Turns out it was something else lol. Thankfully it did not leave me stranded at the beach the day before. The harmonic balancer fell apart right when I started it yesterday.
Turns out it was not a belt squeak

Is there a way to check these?
Like pull the belt and see if the HB can be moved in and out by hand?

You could do that. Just put it in gear and pull the parking brake. It would spin on the deteriorated rubber. If the balancer is 20+ years old, probably a good chance it's not good. I needed a Harmonic Balancer Puller and Installer Tool to get the new one on. https://www.amazon.com/dp/B0DJKX35TJ?tag=wranglerorg-20
Man, I recently went through the same thing. Replaced every moving part of the accessory belt path, and finally figured out it was the HB out on a trail when it failed completely. Got it off the trail and waited over 4 hours for a tow truck to get it home, but it could have failed in way worse places.
Since I started hearing/reading about this issue a few years ago, I've gone and put paint marks on all of mine, that way I can quickly see if they have rotated whenever I want to look.

Mine walked out towards the radiator. Didn’t notice it initially, until I seen a picture of a new one online. The inner and outer should be pretty flush.
Front side, new one on the left:
Back side, new one on the left.

So Ive had a belt squeak for a few weeks, I checked my idler pulleys and such and all seemed 100%. The other day I was talking to a friend about the belt squeak and we opened the hood, we could see the balancer pulley doing the hula which i assume was causing the squeak, either way I ordered one and will replace it this week. Hopefully a dampener and belt solve it, if not it needed to be changed anyway. 120K
I got the Doorman off Amazon, and so far it seems to be fine.
