Long story short I have changed out all the belts (the main accessory drive belt twice), changed the idler pulley and rebuilt the tensioner pulley.

Yet I STILL have a violent squeal under the hood, belt dressing or WD40 oil quiet it for short periods (and are making a mess under the hood).

Any thoughts or direction on the matter would be appreciated.

I have the exact same problem. I was told that there was a service bulletin for the alternator bracket being out of line causing it or something like that. Hope someone chimes in!

what is that part? ^^

mine sometimes squeal, but only after it rains (humidity), or if it somehow get wet.

loose belts will tend to get dust or moisture under them, causeing a squeal.....

to tight belts will just squeal period sometimes...

If the TSB was released in '99, can it still be applied to a 2002?

i had a squeak, it was the top AC idler pulley, replaced it, and it was good as new.

AC idler pulley could be the prob.

Seen a mechanic once fix a new squeeling belt by holding a flat screwdriver tip to the backside of belt as the engine idled. This scraped of glue or some coating that was causing the sqeeling. It worked.
