I just purchased a 2007 3010 Mule, and I'm checking all of the adjustments, when I noticed that when I'm in 2WD, and I push the Mule forward and backwards, that the front driveshaft always turns. Should this be happening? I would think that the front driveshaft would not rotate if the 2WD/4WD selector is in the 2WD position. Are the front wheels turning this driveshaft in this situation and it isn't actually connected to the transmission? If that is the case, does this mean that all of the axles and driveshafts from the front wheels, all the way to the rear trans-axle are always turning, even in 2WD mode?
