Hi,

I'm not sure what an idler bearing is unless they are referring to the idler pulley bearing. The idler pulley (which rides on a bearing) is located on the front of the engine and the accessory drive belt (serpentine belt) rides on it. I attached a pic for you to see. Let me know if that is what they are talking about.

Also, let me know what it sounds like. If it is loud enough for you to record with your phone record it and upload it for me to hear.

Take care,
Joe
