The axles will only be engaged when 4WD is used. If newer trucks are similar to older ones, they use a one way clutch in the wheel hub to engage the axles to the wheel; put it in reverse in 2WD disengages it. You should never see your axles rotating in 2WD. If you are, you've got some serious savings to be had just be disengaging them.
