If noise stops suspect u-joint on driveshaft or bearing on bevel box input or transfer box output or the transfer box itself. If still knocking from the wheel station you know your problem is the wheel station itself, remove the outer hub cover and remove the sun gear and replace the cover. Move the vehicle carefully in a straight line. The tracta joint and bevel box will be disengaged and should remain stationary. If the noise goes away your problem is there and you will have to remove the wheel station to further diagnose. If the noise is still there you will have to dig further into the hub itself as this may be a bearing failure or a broken gear in the reduction hub.
Thanks, Jim. Good logical diagnosis. We've inspected brakes and suspension so far. All looks good.
