pulleys??

[60sec_assassin]

Does anyone know where I could find or has the part number for the two idle pillows on the '04 MM? Think the bearings are about to go in one of them so i'll just swap them both out...they have never been changed since I bought the car in 2004

Also, the belt can set up a howl. If your over 60K miles I would change it too. They almost always "look" good but they crystalize and slip or make like a bad pully.
