I don't know i alot about cars but i have a noise coming from the the pulley assembly. i just put on a new power steering pump pulley because the old one shot off when i was driving it. ever sense then it has been making a loud rattling sound. can any body tell what i can do to stop the noise.

 

I would take the belt back off and check all the pully's.Check them for any play and make sure everything is tight.Pay close attention to the idler pully these go bad. Also make sure the power steering pump is alingned properly and tight.

 

I would check the bearings on your pwr strngpully that was probably what caused the old pully to go.
