Bearing noise
All things were good. The price was reasonable, shipping was free, and delivery was prompt. Unfortunately, I have doubts about the quality of the alternator. It is operating correctly and producing the correct electric output, but it is making some bearing noise, which is concerning. Since it is already installed I'm going to run it for a while in the hope that it will work it's self in before I go to all the trouble of uninstalling and returning it.

Works great!
The part is fantastic and is operating better than the old one for sure. No more over charging my batteries finally. Excellent shopping experience. And best price I've found!
