I went through this a while back. It started real faint and only in the morning after the truck sat over night. It was fant but could hear a chirp after start up. After a trip into town the chirp was gone. About a month after it started my water pump burst soaking my belt. Needless to say a new belt was a must after that good soaking in coolant. I washed it several times and whined like a pig. After the w/p replacement it still had a squeak. Replaced tensioner and idler pulley and no more squeak.
Sometimes it can be a pulley, or a bad belt. Even a miss aligned p/s pulley.
What i did learn from all this is the weep hole for the w/p is above the harmonic balancer that the belt rides on. The faint squeak i originally herd before the w/p burst........ yep it was the weep hole doing its job, but weeping on the belt causing a faint squeak. Thus a good belt and other components belt related but a w/p going bad can drip on the belt causing it to squeak.
Just something to check! good luck i know this is a pita.

ON THE 7.3 THE TENSIONER CAN GET WEAK CAUSING A SQUEAK FORD IS THE ONLY REPLACEMENT I SUGGEST. AFTERMARKETS JUST DONT CUT IT. AS FOR BELT DRESSING IT WILL MAKE A SERPENTINE BELT SQUEAK WORST THAN BEFORE DRESSING ONLY WORKS ON V-BELTS. AND LASTLY WHAT KIND OF BRAND OF BELT DID U USE SOME ARE BETTER THAN OTHERS I SUGGEST A GATES. GOOD LUCK
