Serpentine Belt Tensioner Pulley making noise ... replace just pulley/bearings? ---

[alwayscode390]

I just put on a new belt, and now my serpentine belt tensioner pulley is making noise like the bearings are going out.

Its more of a rock crushing sound that's loud when the belt bounces off of it. My friend and I listened with a stethoscope and its definitely coming from the pulley itself.

It gets A LOT worse when the A/C is putting a load on it.

The tensioner isn't bouncing near as much with the new belt luckily.

Can I just swap out the pulley/bearing combo without replacing the entire tensioner?

I'm thinking this is all I need, what do you think?
