I get chirping front belt area and a light squealing. when I turn A/C on squealing gets noticeably louder. Tried changing out alternator based off what I read. That made it worse. What should I look at next?

Chirping seems to somewhat on the driver side. Squeal has been harder to determine as it is so loud / seems to be the whole front.

Have you replaced the serpentine belt? They do wear out especially if you had a bad alternator pulley.
A bad alternator pulley also can severally wear out and weaken the tensioner spring for the serpentine belt tensioner due to high cyclic bouncing; so you should consider replacing the tensioner pulley as well.
IDParts.com sales a nice kit with a new belt, tensioner pulley, and idler pulleys: LINK> Serpentine Belt Kit (Liberty CRD)
