What is this called?

So I have a whirring sound from my engine, narrowed it down to this patricular wheel off my A/C belt, but its not the belt itself. I need to go to Repco & pick up a replacement bearing, but I dont know what the part would be listed as. Here it is:

Thats the Idler Pully. They are a common issue for noise. you can pick up a new pully, or the bearing on its own.

yep, that's the idler pulley

I would not pick up a junk yard one, If trying to get a used one out of something that just stopped running, I have pulled 6 of these from junk yards all make a noise, all slightly different but all make noise, My original one started making noises after my pathfinder sat for a few months without being started. (i know bad on me) but it seems like the bearing dose not like not being ran. Just thought I would throw that out. I no longer run the AC belt so problem solved:)

considerin they are between 15-30 bucks (shippign being the killer factor across the pond) I personally wouldn't bother with a used one anyway unless the price was 'right' if you get my point...

I just put some Rost-off and then some spray grease on them and they quiet down for a while..

I bought a small grease gun with a needle end on it and stuck it in rubber piece in the middle and greased it never make a sound since!

Take it off (easy) and take it apart. See if the bearing is crunchy; if so, toss it or if not, lube it. Reassemble and install...

 

Take it off when the replacement is in hand, toss it and install the new.

 

It simply comes down how much interest you have and which is worth more, time or $.
