Alternator noise - on its way out?

[esevx5]

Seems like one issue after another on my N52 (215K miles)

This noise stated today and seems to come from the alternator. I think its still the original alternator

Could anyone confirm that has been in this situation before?

Ooh that's a horrible noise. Remove the serpentine belt and spin each belt driven accessory by hand. Hopefully you can find it.

The thing is, that I had just changed all the belts and pulleys less than 15K miles ago, so unlikely any of those components


But ill give it a try

Any of the spinning parts can be the source. It sounds like bad bearing: PS pump, alternator, AC. Take off serp it disconnects all at once.
