Oh hey, guess I never provided a follow up for this. Mine turned out to be the belt tensioner itself, not the pulley. it was a pain in the ass to replace because one of the bolts broke on the way out and you can't see what you're doing, but its a manageable project.

I just took care of mine as well. It was tensioner pulley but the idler pulley was also bad.

I replaced the idler pulley but I was unable to ger the correct tensioner pulley. Both advance auto and autozone did not carry the correct one. My tensioner pulley needed to be bolted to the tensioner assembly and the pulley they have could not be bolted down in any way. I''ll have to buy it from Bav auto.

For the time being i just impregnated the bearing with a little grease to prevent further damage.

My idler pulley went a couple years ago in a hail of ball bearings at about 6k rpms getting onto the interstate. Only time my car has ever stranded me, and I just so happened to have the replacement part sitting in the passenger's seat.

Just did lower tensioner pulley... Fell apart in my hand when I took it off
Still squeaks (less) sounds like the upper wants a change too... will get to it on next oil change

When u say it was the tensioner itself how did u figure it out...was it from the compress-decompress or something else?

I finally figured out mine was bad because there was the tiniest amount of play at idle and the tensioner was wiggling back and forth a little. Also, the bushing on the tensioner was blown to all hell which was a pretty good indication. Taking a long extension or stick of some kind and using it like a stethoscope is surprisingly helpful.

It takes patience, but move from place to place with your ghettoscope and see where the noise gets louder until you zero in. There are lots of things that can squeak on the accessory system.
