Replace just tensioner pully?

Hi,

I think my belt tensioner pully sounds bad, is it possible to just replace the pully or do I have to replace the whole tensioner?

What is it doing or not doing besides noise and what kind of noise?
If it is high mileage and is losing belt tension or has movement front to rear with belt off I would go the hole thing.
Gates has the hole thing at a good price.
But if the tensioner checks out good you can just get the pulley.
You call.
