My Buick with 97k miles on it has a squeak coming from the alternator. I know it's the alternator since it was taken off of the car ~3 months ago when it needed to come off to access the belt tensioner. Rotating the pulley by hand gave a small bit of roughness and a very soft squeak on every revolution. Now it's squeaking louder when I let off the throttle. It's only audible from under the hood, not from in the cabin yet. The serpentine belt was replaced today, the automatic tensioner is reading fine, and it's still making noise.
Am I being a hypochondriac, or should I get it replaced before it gets worse?
