    You did make sure by turning it by hand without the belt right? And they really don't sell alternator repair kits anymore so you may have to get a new alternator all together.

    There are still some re builders there. Search in your local area and see if you can find one. They might replace the bearings for $30. I have one right down the street from me. Be careful buying a new (reman) alt. I had a nightmare last month with mine. I have a "bosch style" on mine, finding one was a PITA. Then after I found one, I went through 6 in one month!! One most of them the bearings went out within a week, two of them did not put out proper voltage. I did not add the 4 that had bad bearings right out of the box and I would not put on my truck. There was also one with a cracked case right out of the box. I ended up spending the $20 more and bought a brand new Bosch

    sounds like you had quite the dilemma, glad you got it all worked out...
