1997 993tt Viscous Coupling, limited slip

Transmission and Clutch

Vehicle Information: Model: 911 Turbo; Year: 1997; Body Type: Coupe; Total Mileage: 41000;

I suspect that my viscous coupling may have failed. Jacking up one front wheel, it will turn with minimal drag, like what you would get on a car without AWD. Is this a reliable test for the VC? As for the limited slip, with the car on four jack stands and in neutral, turning one rear wheel, the other rear wheel does not turn. Shift into gear and turn one rear wheel, the other rear wheel turns in the opposite direction,Is this normal for a car with limited slip?
