metallic engine rattle cl55

Im getting a sharp mattalic rattle up front near the belts. I searched and it seems like it's the inner Bearing on the 2 piece idler from what I've read. I'd love to get a second option before I start ordering parts. Here is the video I took.

Take off the belt and fire it up to see if the noise goes away. Usually, with the belt off if you spin and try to wiggle a bad idler you can tell if it is shot.

My inner idler pulley broke in half a couple of weeks ago and the car went straight down on its ***.

As an emergency i found that i could take both the pulleys off and swap the front pulley over to the back to get the car started, raised, and drive a short while back to home.

But personally i would get it seen to BEFORE it breaks off.

Im pretty sure you can get a bearing kit pretty cheap for those.

Is this the right part... Seems way to cheap?

No, your idler pulleys that you are referring to have grooves in them for the ribbed belt to go on.
