I have a 1999 bigbear 350 4x4 and it has a rattle or knocking sound in the clutch, I posted before thinking a rod but with a stethoscope I can here it is in the clutch,Can anyone shine some light on this for me. It only does it when you give it a little gas in gear for a few seconds. I think I found the noise, its the counter weight on the centrifical clutch.
