I had the front bearing in my alternator go bad. I kept hearing a noise at highway speed, but, couldn't figure out where it was comming from. I could turn the fan, and the engine, and alternator would turn... Looked for the problem for a couple of weeks, but never found it. Then it started getting worse. I took the alternator off, and couldn't turn it by hand.....Replaced it, and now no noise.
Need to check things out closely, and maybe you will find something dumb, like my problem.
