Locked center diff, then the speed of the front driveshaft will match
that of the rear driveshaft, the right front wheel will do whatever
speed it feels like and the left front wheel may even rotate backwards
due to the open front diff.  No torque is shifted to the inside wheel,
in fact, almost all goes to the rear.

This time, not much torque goes anywhere, excess torque produced by
the engine causes the engine, front driveshaft and left front axle
to accelerate - the wheel spins.
