belt squeak, but not the belt? help please

Elusive squeak from drive belt(s)
I have a 2000 Z-71 4.8 all manual. It developed a bit of a squeak around 275000 miles. I looked and looked and narrowed it down to the ps pump. Not wanting to get one at that time, I let it go. Put the truck on minimalist duty and let it sit. Got a 2005 Escalade from where I work. 6.0 that runs good, 250k on it. 1000$ bought it cuz the ps pulley (and shaft) came out the front of the pump body, slipped the belt and made a helluva mess. Owner couldn’t drive it obviously and dropped it and title at the shop I wrench at. I also got. 2003 Tahoe 5.3 auto engine fire survivor. (Barely) I used the ps pump etc to fix the Cadillac. Now I’m preparing to drop the 6.0 in the z-71 and call it a match made in heaven. I never seen a 6.0 in a first run LS z-71 with all manual drivetrain. Lol, I love that platform. Essentially 10spd w 4wd if you can shift it. Some slight mods to the gear boxes will aid in manual SOTF activity.
My point is, a belt squeak that is hard to nail down, check the LS pulley for any thrust play. It needs some, but any play that you can feel is to much and the pulley is walking out of line with the rest of the accessories.
good day
