Alright so I think it's not a bearing. But when I'm on the gas I hear a squeaking and rattling from the engine. The rattling has always been there when I accel hard and it rattles kinda loud. The squeaking is noticeable over 1000 rpm. Even at idle with the clutch out you can hear something too. It's not loud but it's there. With the clutch out it it's still there. I'm guessing a belt? But the rattling concerns me. Always been there, just never knew what it was. My dash lights also dimmed under acceleration

 

idler pulley going bad??? and the lights diming = get your charging system checked. I think autozone will check it for free.

 

Yeah the pulley looks like it needs to be replaced. The belt has a cut in it. Like it's about to snap in half, so hopefully a new belt will fix that.
