Title: Noisy Chev Alternator
Post by: Scoobum on March 19 2012, 12:25:28 PM: I swear the worse thing ya' can do is store a vehicle...but anyway. The alternator is noisy on this 1998 Chev 4X4. Is there any way of lubricating the bearing?

From what I remember - alt bearings are sealed. I guess you could soak them in oil, but that wouldn't last. You're sure it's the alt and not the tensioner?

Once the bearing seizes it will screw the belt up as well as give you a big headache if you're driving it around. I've seen them lock up and break the case before so keep that in mind.
