Alternator bearings

[ewcmr2]

My Alternator bearings are starting to chirp when cold...
I’ve searched and many people have had alternator bearing problems. I’d like to order new bearings to have them ready to install rather than disassemble alternator and then order parts.
Has anyone come up with replacement bearing part numbers or measurements?
There are threads with Denso alternator part number guesses, how about a confirmed replacement Denso alternator part number?

Are you sure it's your bearings?

I had a little chirping that cleared right up with a little belt conditioner.

That’s definitely possible.
I took the belt off and none of the accessories felt bad. I had a spare tensioner pulley in trailer so I swapped it — no change.
Since none of the bearings felt bad I’m confident I’ll get through the weekend without a problem. I’ll give the belt dressing a shot when I get home.

Belt dressing made it squeal like an old/loose belt, then it became quiet.
Replacement ordered.

Thank you! Thank you!

Seriously, glad it worked.
