02 Explorer pulley chirp- making me nuts

[Reitman]

Hey Ford guys-

My fiancee has an 02 Explorer Eddie Bauer that has a chirp in one of the pulleys. I replaced the tensioner, which was the most obvious culprit to me. Stopped for a day, then the noise came back. Replaced the idler pulley. Stopped, then came back. Pep Boys said it was the bearing in the alternator. Replaced it, noise stopped. A day later..noise is back!!

It began as a chirp when idling. Now it gets worse with RPMs. The only thing left that I would do myself and not pay out the nose for is the belt, but I have some doubts about it being the belt.

Anyone have thoughts?

Thanks

Sean

belt dressing spray. just spray a bit on the parts of the belt front and back that you can see.

don't try spraying it on there with the truck running [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img]
