I got the alternator off the car last night and will take it in to a shop that can bench test it. The bearings feel really good, so as long as the windings aren't a mess, then I should be able to get the offending parts replaced.

Notes on the removal...
If you have never had to take off the serpentine belt, it can be a real pain if you don't have the one key tool to release the tension from the tensioner pulley. There is a square hole at the pivot point for the tensioner. This hole is 3/4" and accepts a 3/4" drive breaker bar or ratchet nicely. I borrowed one from my uncle and made getting the belt off take seconds. I fought with it trying to use other tools and solutions that I found around on other boards, but this method worked the best. If you have to, rent this tool and make your life easy. It will be well worth your time and money.

Also, there are 3 bolts behind the power steering pulley that can be tricky to get out. Use a combination of adapters to make an extension long enough to get into the hold in the pulley, but no so long that you can't get a ratchet on the end. I found that the shortest extension is just a little too long. Even a deep socket for the lower one is too long with the ratchet is too long. From the ratchet I used a 1/8" swivel, 1/8" to 1/4" converter, and then the 12mm 1/4" drive socket. It just barely fit, but after I got things loosened up enough was able to take off the ratchet and finish loosening the bolts with my finders using my custom extension.

I hope that this saves some people some time and headaches trying to get these parts off.
