Do you basically just get a new alternator to fix this?

There are shops that repair alternators. They may charge you 70 bucks to fix, instead of laying out 400$. Are you sure it's the alternator bearings and not the belt?

yeah im sure some place that rebuilds alternators could take it apart and grease it up or replace the part. call around i know you will find someone to do it. and whats that about laying out 400$ ive had to replace my alternator twice and its never come close to 400$

Well if you buy a rebuilt one from Autozone and such - it's way cheaper - but wouldn't recommend. That's probably why you had to replace yours twice :P

At bavauto.com Bosch units run about $350 + shipping. About same at the dealer.

no i bought new bosch ones, non rebuilt, i wouldnt buy an alterantor off the interent from bavauto. when theres local shops around here that sell the same product for way cheaper! and you dnt pay for shipping... maybe they are more expensive but i get mine for cheap in my town, specially after my core exchange.

I'll buy a new alternator if that will fix the problem. The thing is that I'm not exactly sure what is causing the noise. I need to ask Autotechnica, he mentioned something in a previous post about removing some fan assembly associated with the alternator.
(not the fan delete mod but something else) I was just curious to see if anyone else knew anything. THANKS

before i went out to buy a new alternatori would first call around describe your problem with it squeaking and ask them if they can take it apart and fix the squeak if you get a bunch of no's then i guess buy a new one

It might just be your alternator pulley. I'm almost 100% sure that's what my squeeling noise is.

can you replace the pulley? or does the alternator have to be replaced?

You can replace thepulley seperately. You canget thepulley for 40 bucks from Bav auto. That's of course if it's the alternator pulley thatneeds replacing.. Could be either of the three pulleys... or is there more even?

An easy fix andupgrade would be underdrive pulley setup. hey replace the pulleys and the belts which should definitely solve your problems. That's what I plan on doing.

go look at your pulleys look to see if it looks like it has a lot of wear... see if its in its groves all the way.. see if its tight enough, you shouldnt be able to turn the belt more than about 90degrees
