New Magnum Xl and 4.10 gears. I have a slight DECEL whine ... probably not enough to worry about. But, I’m curious .... If the whine starts at DECEL, but then goes away when you disengage the clutch and coast, would that imply I’m actually hearing something other than the rear end (like transmission or engine harmonics)? Or does rear end DECEL whine go away with clutch disengagement?
