This system works fine in most daily driving situations but this system has faults which will become more apparent on slippery surfaces. For example when driving on snow, one wheel may have little or no traction and hence the torque created is negligible and as the diff
transmits the torque 50/50 between the two wheels, the other wheel gets 50% of next to nothing which is why the car will not move forward.
So since the one wheel had a snapped axle, it was like the "slipping wheel in snow". So the torque is very little. So the other front wheel also got little to no torque correct? Makes sense.

But what I still don't understand, is the "slipping". What was slipping? It wasn't just that there was no torque, the thing free-revved like a slipping clutch. That is what I don't understand, and wish I understood.
