ok so my truck just started making a rattle noise 2 days ago. i cant find where its coming from but i can tell when its doing it. maybe someone has had this before. its a deep knocking noise but only when i push my clutch in and try to engage it in gear and only when im releasing my clutch to take off. but it did it once yesterday at idle then stopped. but started again as i tried taking off in first. when im driving it has no clicking/knocking. but when im al idle and put tranny in gear with the clutch pushed in. i thought it may be the throwout bearing but i thought they squilled and didnt knock/click. and it gets louder and faster as i start rolling in first and the more i let off the clutch.
