Default alternator bearings

alternator bearings..

is it possible to change them?
where can i buy them?

mine makes a dry bearing noise when the lights are on, the heater is cranked, and the fan kicks on. the noise is a loud, constant, , high pitch that comes from the alternator and does not change pitch with RPM. i'm sure the noise is from the alternator. sometimes the belt squeaks too, but only because i'm afraid to tighten it. -just wondering.

sounds like if you go here and type 3000 and click play.

the sound stays that pitch and goes away if you rev it for a few seconds, or instantly if you turn the blower motor off.

found the bearings:

Weitzel's D.C. Electric in Norwalk, Ohio - 419-668-2844

but the guy there said since the noise doesn't change with RPM it's likely the stator. he said if i touch the alternator when it's making the noise it'll be "hotter 'n hell".

he also said they are soldered and pressed and are such a pain to change i'd be better off replacing the alternator, which is what he'd do. very knowledgeable people to speak to if you ever need to talk with someone about an alternator.

yeah. i agree. i have used poor judgement by scheduling a 10 day florida vacation right after christmas. the combination of buying gifts and saving vacation money is making my wallet pucker. after speaking with that alternator guy, i see there's really no way around it. i'd hate to wait and have it fail in that special way that fries the ECU.
