But looking at its design, it should divide almost 50/50 the torque between front and rear prop shafts with the help of an open differential. But isn't it so that the rear wheels should be connected to the transmission at all times? (NV140 doesn't have the possibility of 4-lo nor Neutral, right?)
I know there was a discussion a while ago about whether it was possible to remove the front drive shaft to allow for dyno testing of the rear wheels. Consensus was that the rear wheels would not be powered.
I think the power will go to wherever there is the least resistance. If the front driveshaft is disconnected (or in this case, if there is an axle that can freely spin), all the torque will end up there. That's why the QT1 has a brake controlled traction system, to try and slow a spinning wheel to allow torque to go elsewhere. This would also explain why the traction control system was freaking out a bit, as well.
