Personally I do not see how rotating the diff will change anything. The diff is a mechanical device that will operate the same no matter which way you face it. From my understanding a normal diff transmits more power to the side that has the least amount of resistance in order to keep things moving (hence spinning wheel off the ground effect). So the amount of resistance (or lack there of) on the front or rear diff will determine which one gets the most power. How will the weight of an oil change that theory?

There are diffs that claim that they can reverse that force and work in the opposite way sending more power to the wheel with the most resistance. I believe the 1/8 "Torsen" diffs claim to do just that. In their write up it states that there diffs transfer the power to the wheel that is not moving or shows resistance. So in theory that would mean that it puts more power to the rear wheels of most vehicles due to the heavier end of the truck/buggy, or whatever. Correct me if I am wrong.
