Rear going south possibly

Today while my car was jacked up to change drag radials (EM brake was off), when I went to the first torque setting of 60lbs with my torque wrench, the wheel spun & couldn't hold unless I held a spoke..
The other side did the same, spun freely..
Is this a bad rear or sign its going.. Before it always held torque to 60 lbs no problem at all, and then I would lower the car & torque to 80lbs, then 100..

-nevermind, 80 is the 'lubed' torque, and 100 is the dry torque.

I am curious about this, I would have thought they should spin? If not then mine probably has an issue. Should one spin and the other not (if you have the car up and are only turning one)? I'd love to know too!

I've always ended at 100

Lots of cars have 'peg leg' rears, where when up in the air, and one wheel spins, the other goes in the opposite direction. My 1500 truck has a different type of positive traction in the rear, which I think is a more positive engagement, that won't allow any slippage between the two rear wheels once engaged, but it doesn't stay engaged during normal driving, only when wheel slippage is detected, does it 'lock up'.

There are many different types though, among the different manufacturers.

One thing that I always thought was funny is the 4 wheel drive vehicles that have 'open' differentials in the front and the rear. They aren't really 4 wheel drive, you could actually get one stuck on 2 wheels if they were diagonal to each other. My friend had a jeep that was a good example of this, we even got it 'stuck' to test the theory.
