I found my 2014 Explorer alternator was making noise. I pulled the unit, some of the noise was coming from the one way clutch coupler and some from worn bearings. The front bearing was easy to find a replacement. The rear bearing is stumping my search's. It is a NSK 6002DG6 15x21x11. I finally called NSK and they said that number no longer is in production. I have searched the web and found one bearing this size with a ring groove in it, it's located in India. The reason I bring this to the forums is to see if anyone else has been down this road and found a replacement bearing. I am wondering what the tension ring is for since I can't find any other alternators that use this. Check out my pics, any help is appreciated.
