Doesn't solve the debate, but these guys do a pretty good vid for anyone interested:No. It’s an open diff so if one wheel lifts off the ground, all the power will be sent to that wheel. Now with that said, all JLs and JKs have brake differential as part of the traction control. So if one wheel is spinning, the computer can apply brake to the spinning wheel which then causes power to be directed to the other wheel. There is debate on how well this works compared to a limited slip or locking diff.
