garage method of checking lsd function

Anyone know of a quick and dirty way of checking the condition of the OEM lsd in a 930 4 speed box? Trying to gage if mine is still functioning or not.
I thought there might be a way of jacking the car up on blocks and measuring the forces to turn one wheel while the other is blocked from rotating.
Is this a logical approach, and if so how much force approx. should be expected to turn the unblocked wheel by hand as long as the diff is in good shape?
