My AC Pulley has started to make a pretty loud rthymic squeaking noise.. Does the pulley/bearings just need to be replaced? Or is there more involved in it? Looked at old threads .. Didn't really find just a specific thread on just the pulley making noise. I was going to attached an mp3 file of the noise but it looks like that format is not allowed?? WTF is up with that?

I use a wooden yardstick and put one end on the part I want to listen to, then put the other end on my thumb and that against the front of my ear. Put a very slight bow in the yardstick and noises will then transfer up so you can listen. A good bearing will sound smooth and bad bearings will have a rumble as you listen.
