Please do a search on Autozone alternators. You will find numerous stories of early failures and weird, noisy operation. Of course, not every one is bad but the amount of issues makes buying one unwise.

Mine lasted 4 miles, returned it and got my original failed unit back to use as a core for a Bosch rebuild.
