I Love Corolla's!
I've been hearing a grinding noise coming from my engine recently so I took a look to see what was making it. The grinding would occur when I start the car, shift gears, and let go of the throttle. I noticed that it was coming from the serpentine belt side so I looked there and I noticed there were metal shavings on and around the alternator so I was expecting it to be my alternator failing. I took the serpentine belt off and after spinning each pulley, the alternator pulley had a bit of a wobble to it and I heard a tiny scratching sound as I spun it. I also noticed that it would freely spin in both directions which I heard is not supposed to happen on an OAD alternator. So, is it the alternator pulley that failed, the alternator itself (I don't think it's the alternator since it works fine and my car doesn't have trouble starting), or is it something else? Any help is appreciated.
