Yesterday I drove the 3k and noticed a sort of rubbing noise when I let off the throttle. It doesn’t do it if I’m on the throttle, even if I’m barely giving the car hardly any gas. As long as I’m holding it steady or accelerating there isn’t any noise at all. If I let off or down shift I get the rubbing/grinding noise. Sort of sounds like the getrag rattle or a bad throw out bearing. The noise goes away when I push in the clutch. Can the half shaft bearing that bolts to the engine make this noise? I would think it would do it all the time if it was that bearing though. First thing I always think now when I get any drive train noise is the OBX LSD or the Spec clutch.
