Sounds kind of like your alternator. But I cant really hear the whine in the video. Just put a stethoscope or a pipe or something and put your ear to it to see which pulley is whining.

Is it broken?

There are a few bearings and one of them is dead:
AC compressor
alternator
idler pulley
tensioner pulley.
Both pullies are for sale from any autoparts store.
bearings of compressor ($15) and alternator ($3)are available too.
Weak tensioner can make belt noise.
PS pump can make noise too, check fluid.
Buy stethoscope.

I dont think you can easily replace the bearing in the alternator.

I hope the noise not from inside the engine.

So any idea idea where I can buy ONLINE these bearings for the AC compressor and alternator?

And any tips how to replace them?

Or at least if any body has idea about the bearings size so we can source them from any hardware shop

Thanks
