what about that would make it not truly a 4wd? an open diff puts the same amount of tq to each wheel, but if it only takes 50 lbs ft of tq to make one wheel spin then the other wheel only gets 50 and sometimes thats wheel wont have the power to move but that doesn't mean its not being powered.Is a 4X4 truly four wheel drive if both axles have open differentials?
we're getting a bit off topic i guess but the power is equal to both wheels on an axle, the reason you wont move with one of each in the air is because of how little power it takes to spin those wheels in the air, the same amount of power is being applied to the wheels on the ground which is obviously only enough power to spin a free wheel so you don't move. just because your not moving doesn't mean that the power isn't equally distributed. LSDs just force more tq to be applied by not allowing a wheel to just free spin without enough tq being applied to turn the other wheel as well. forcing a load on a free spinning wheel increases the amount of tq going to that wheel and and in turn an equal amount is given to the other"what about that would make it not truly a 4wd? an open diff puts the same amount of tq to each wheel, but if it only takes 50 lbs ft of tq to make one wheel spin then the other wheel only gets 50 and sometimes that's wheel wont have the power to move but that doesn't mean its not being powered."
That comment was towards the Z71 thing.
True, they are being driven but not all 4 wheels can provide the available torque due the open diff.
If you have open diffs and no ABLS, lift a front and rear wheel off the ground and see if the vehicle moves. Power will follow the path of least resistance.
