Ok, first off i noticed a quiet, yet irritating squeek at idle or at low rpm that kind of gets louder and quieter as it pleases. The belt is fine, i put a bar of soap on the belt to check but the squeek was still there. So it must be the bearing right? A new idler is only like $40 at a local parts store but i would rather pay like 6 bucks for just the bearing and install it myself. So my question is, where the heck can you find just the bearing? i hear this is pretty common, has anyone had success fixing this without paying for a whole new idler?
