Noisy Alternator

[puppetz007]

I've searched the forum and couldn't find anything to help. The alternator on my 01 shrieks like a banshee when its started up in the cold. I've tried adjust the tension of the belt and tried to get a temporary fix with WD-40. Any ideas on how to fix it? BTW it is an Autozone Duralast Alternator, not the ideal one, but budget necessitated it at the time.

See if you can grease the bearing on the snout. I have zero experience with Toyota Alts but i was able to do this on an old Honda and my current VW. they made a little noise so i took the belt off loosened the bolt and greased the heck out of it.

My OEM one when started to make noises, were the bearings. Replaced with new ones from ebay and its silent again.
