96 Tacoma 2.4L 2rz motor

Hello my 96 Tacoma 2.4 L I had noise coming from my pully. Like a bearing is no good I’m guessing. Well before the engine turn off on it’s own. I saw that when the truck was idling one pully was not spinning straight? It looked wobbly. And the noise was coming from the pully. One was spinning straight the other one was not. Could you please help me out. I should of took a video before it turn off but I didn’t. Hopefully I explained it right....

 

Replace that pulley for sure.

 

Do you if it’s some kind of bearing a name for something so when I tell them they would know ?

 

Depends on what it is. Take a pic and circle the pulley and post it.
