I'm not sure I understand the theory. There are two opposing forces at work
on the axle: 1) the inertia and friction at the wheel hubs, and 2) the
torque from the engine via the transmission at the output flanges. Which
side are you saying is applying greater force than normal and by what
mechanism?
