My 200 is making some funny noises. It's when I'm on a light throttle into the overrun, the transmission bangs and vibrates. I've checked both propshafts and they are in good order, all the joints are fine with no play or stifness. The difflock is not on and I can feel no play in the flanges the propshafts connect to. I can feel the vibration through the transfer box gear stick but can feel very little through the main gearbox stick. The main gearbox is quiet with superb gear changes, even into secind when cold! I've come to thinking the transfer box is the culprit. I ran without the rear prop attached last week for a few miles and with the difflock on, the noise was horrible! Am I thinking the right way by a finger pointing at the transfer box?
