Re: 4wd terms
One thing to remember about open differentials... and this is not just a
rumor or something that I made up... no matter what is happening, whether either wheel has good traction, poor traction, or one wheel has good traction and the other has zero traction... both wheels always always always (!!!) receive exactly (!!!) the same power to them. The power is ALWAYS split 50:50 between the left and right wheel on an open axle. Ok now you're saying --------... but it's true, really. What happens is that when one wheel starts spinning and has no traction, the axle starts spinning the tire that has the least amount of traction which then presents the engine with little or no resistance to work into. With no resistance to work into, the amount of torque produced drops down to nearly nothing. That "nearly nothing" amount of torque is split 50:50 by the open axle (again, really)... which is enough torque to spin the tire with little or no traction available to it, but not enough to spin the tire that still has traction. So limited slips do not "send power" anywhere, they act by friction or by gearing to couple the spinning tire to the one with traction to present more resistance to the engine... with more resistance felt by the engine, the amount of torque it sends to the rear axle is increased. That additional torque is still split 50:50 but may now be enough to get the tire with good traction to begin moving the vehicle again. So it's a basic fact that both wheels are indeed (really...) getting a 50:50 split of the power being sent to it via the driveshaft. Whether that 50:50 split provides enough torque to the wheel with good traction decides whether you move or not. So all this is why the old trick invented back in Model T days of applying the brakes when you're stuck really does work. It causes the engine to see more resistance so it develops more torque when the tires can't provide enough resistance themselves and start spinning.

Re: 4wd terms
That brake trick works excellently too!
For some reason, the rear drum brakes seem to transfer the torque easier than the front disks, so it is easier to get both back tires spinning than all 4 spinning though I have managed a 4 rooster tail take off a couple times.
