2004---there is a loud buzzing noise comming from the front of the 5.4 engine.right behind the radiator on the passenger side. It does it all the time the motor is running. It kind of sounds like powersteering but it is comming from the wrong side of the engine. Any Thoughts THANKS FOR READING THIS POST

 

Idler wheel bearing? Check all the bearings in the serpentine travel circuit. You may have to take the belt off to do this.
