Chirping from rear wheel

I did a bunch of research for why one of my back wheels (unidentifiable from the cab). It’s rhythmic with the wheel, and worse when cold, but also inconsistent. I don’t think it’s a shot wheel bearing, I’m only at 69k and it’s a almost brake like squeak not a grinding, and I don’t think it’s a shock bushing squeaking. Anyone got any ideas?!

Wear indicator rubbing on rear brake pads? The rears wear out quicker than the fronts on these Wranglers. Worth a look.

Jack up the rear corner and rotate the wheel/tire, listen up close. Remove the wheel and eyeball the thickness of the pads.

My right rear has a chirping that is caused by the little spring that holds the brake pad in place. Either the rotor is warped or the flange on the axle bent is causing the pad to move slightly in and out. I put brake pad grease on it and it quieted it down for about 3 months, but now it is back.

I have a rear chirp/squeak that seems to be caused by the parking brake, though the dealership couldn't find anything definitive.
They "adjusted" the parking brake, and that did reduce the frequency of it happening, but didn't eliminate it.
Mine's not rhythmic or rotational, though.
It occurs going over bumps, when the suspension's articulated just right, or when starting/stopping the vehicle.
But it's only selective or intermittent, so it's strange.
Before they adjusted the parking brake, I was able to jump up and down on the rear end while the tech listened underneath.
He said it would stop when he held onto the parking brake assembly.
At its worst, it sounded like chirping birds following my Jeep around.

Check the brake pads first.
For me it was a bent flange, here's a couple of videos of what it looked like:
