Squeaking Alternator

Squeaking Alternator
I pulled off my belt and randomly just spun the alternator pully and heard it squeak. It gives off a little chirp every turn or so. The pulley spins freely and does not have any play and the alternator voltage output seems to be fine. I was thinking it might be the bearing but it sounds like the squeak is coming from the middle or back of the alt when I spin it. Do you guys think this is something I need to worry about immediately?

How old is the alternator?
It could come from the bearing or from that the rotor slightly touches to the stator(is this the right word?) , or from the coils.
I wouldn't be worried if the noise comes from the rotor or the coils. If I was you and if the alternator is old I would change the bearings, I would worry about the old and worn-out bearing

The alt has 90,300 miles on it unless it was changed b4 I got the car. When i put the belt on and got the car running there was no squeak that I could hear. Although there were some really small noises coming from the alt. Sounded like little scrapes, but like I said they were very low sounds, I was thinking the squeak would perpetuate but it dident. The problem might get worst later on down the road though. Like you said I probably will have to change the bearings. are there two sets of bearings or just the one in the front?

You could do it your self. Might be a little hard without knowing all the little tricks n stuff. I rebuilt one in school some years back, but I cant remember. As long as you can find the step by step directions you should be able to figure it out. I dont know if its in the manual or not though. Thats what ill prob end up doing my self.
