Ok, I searched around a bit but I wasn't real sure what to search for. This may or may not be a recent problem with my car (may not be a problem at all). I've noticed a very distinct hum/buzzing sound coming from the left side of my car. I may have never noticed it before because I used to have a stereo and it couldn't be heard over the music. And even when the windows are down the wind noise covers it up. So I can only hear it when the windows are up and the nonexistant radio is off. I thought maybe axle going bad because even though it sounds like a hum/buzz its kinda of like a clicking sound too... The speed of the clicking increases with the rpms not with speed because if I put the clutch in and the rpms drop the clicking slows down. And at idle I can't even hear it. It's definitely starting to bug me, anything specific I should look at? Could it just be the belts? or something...?
