It's true that if there is no torque to apply to the worm gears that the
diff will just spin. Even when you lift a wheel there's some torque
applied, but not much. Break an axle and you don't even have the flywheel
resistance of the wheel to bias torque against and there you are, parked.

For the benefit of everyone, I am copying this to the list. Those to whom
I have sent private replies can "talk among yourselves".
First, let me explain that because the Quaife is Torque biasing, it
requires that the wheel that is experiencing loss of traction still have
some sort of torque applied. This will be true if the tire is spinning on
pavement but if you break an axle or lift a wheel entirely off the ground,
all torque on that side goes to zero. The way the Quaife is designed. it
allows all the power to go to that side. But if there is some reduced
amount of torque, the power is shifted to the side with the higher grip.
Check with Quaife, I am sure they can explain this far better than I can!
Cheers,
Joe
