I have a grinding sound coming from my engine bay. I believe I have actually narrowed it down to the idler pulley. It almost sounds as if the bearings have gone bad.
Its tied to rpms, if the rpms go up the sound increases in frequency as well.
My question is: Is this common? and if I replace the Idler pulley does it come with the bearings? Could it be something attached to the idler pulley. All I really know is thats where the sound is coming from.
Thanks,
Justin
