2¢ worth - Just clarifying some of the LSD misconceptions posted earlier and not yet corrected...

The LSD does not transfer the power to the wheel with traction.

The open diff sends the torque to the fastest wheel, as that's typically the wheel on the outside of a turn, and you would want to push from that corner logically.

Off road, with an open diff, the fastest wheel is potentially in mid air, or slipping on mud, etc...and of no use propulsively.

An LSD keeps the two wheel turning at the same speed ALL THE TIME...unless (Unless) the difference in traction is high enough to BREAK FREE the LSD's lock, and allow the faster tire to get the torque.

So - you are driving straight on pavement, the LSD is locked...you turn sharply to the right for example, and the speed the right tire is trying to turn at is just TOO different from the speed that the left tire is turning at, and the LSD lets go, and the left tire (Outside tire), gets the go go juice...and the right tire (Inside tire) gets to coast along for the ride.

If the LSD was too tight for the turn, the two tires would continue to turn at the same speed, except the one tire would be anchoring, and the other dragging its partner along...skidding and chirping, etc.

Off road, the LSD will turn the tires the same way...at the same rotation speed, until break away torque was reached, and it lets go.

This means you get more traction than with an open diff, untill the slippage of one tire is too great, and THEN it lets go.

So - There's no transfer "from the one that slips to the one that grips", a la Subaru's ads, etc.
