'06 Camry has been squealing for the last 8+ years. The serpentine belt squeal was so bad in the month or so before the alternator completely gave up. The belt would be constantly squealing anytime the car would be in motion. At a stop light, everyone would be looking at my car. The original alternator finally completely died one night and I decided to replace the alternator.
I would have replaced the belt, but the, um, unhelpful workers at AutoZone sold me the wrong serpentine belt. As a result, I ended up reusing the old serpentine belt.
To my surprise, the squeal is gone! I remember checking the old Denso alternator for play in the pulley, and I found none. The old alternator's pulley spun smoothly. It didn't catch anywhere. It didn't grind. It didn't wobble. It had 0 play.
What happened exactly?
