whistling noise

[zaueugen]

when the engine idles there's a small squeak, when i accelarat the whisling noise grows lowder the more i accelerate.. could be on of the belts, or the alternator? because it seems to be coming more from the alternator... ????

The bearings in the alternator go bad in that way sometimes. Mine whines kinda like that. Just pretend it's a supercharger, lol.

hahah i know it sounds like one, i was thinking the same thing
so no worries about anything blowing up right?

GEt out a piece of wood ( 12 to 14" long )Push it hard against the alternator when it is running and put your ear to the other end you will hear it if it is the bearings going . they may last a year or 2 that way .

BUMP.

The car I just bought has the rear (alternator) bearing whining. Is the replacement bearing number known/available?

It will be a fun to pretend it is a blower until the alternator, well, blows.

It appears to be a common 12x32x10 bearing (6201 2RS ABEC-1 double sealed) on the commutator end.

And a 17x47x14 for the drive end (6303 2RS ABEC-1 double sealed) on the drive end.

I may even have them on hand.

OK, so the FLAPS parts listings are wrong for the OEM alternator.

The bearings are:
Pulley end - 47x17x18
Commutator end - 23x8x14
