You will need Santech MT2031 bearing purchased at Autozone for $15. I did all of the work from above and used the recommended snap ring pliers in the video.
This is all assuming you have a 4.8. |
No, I have a 3.0 N52N
Oddly, when I turned off the AC thinking it was that, it still whined. I wonder if the 4.8 and the 3.0 use the same AC unit. Also, I have Adaptive Drive, so that might change things.
