Replacing non idler pullies?
I'm not sure on this. I was reading my Haynes trying to figure it out.
2004 5.4 3v... I did a write-up on here about the idler replacement last year but I have a squeaking again and it's from other pullies. If I am not mistaken, one is for the water pump? The crank pulley is down at the bottom and the alternator pulley is attached to the alternator. How do I tell which one is squeaking? Is there an easy way? The water pump one or alternator I could see being the culprit. When it's cold, it squeaks for a while and then goes away. It sounds bad though until it goes away. When wet (like after rain or washing) it squeaks for a bit then goes away. During the summer/spring, I don't hear anything. This is the second year in a row so I'd like to nip it in the butt.

Does the answer now become evident?
Temporarily removing the belt will tell you if it is indeed that alt bearing or A/C compressor /clutch (further isolation provided via the MAX A/C function - enabling the compressor).
It *may* be the water pump itself - does it leak?
Lastly - very unlike the large crank pulley is going to cause this with a fresh new Gatorback .... oh wait, you dint USE a Gatorback
You could always try to clean / burnish the pulley surfaces themselves - along with fresh belt... see if that makes any difference.

Sounds like the power steering pump to me. I know our Fords have a loud power steering pumps when its cold. When it was -20 here both my 07 and 02 with a brand new power steering pump squealed for at least 30 seconds. then went away. My 07 would squeal longer than my 02 tho.
Yep dat booger gots a bearing ( not inna pulley itself, though ).
