Can you test an LSD
#2
You can try testing an LSD by applying moderate brake pressure when you have a slipping wheel to see if it will xfer power to the wheel with the most traction. That's how a LSD should work.
Hope this helps.

It's going to depend upon which type of limited slip you have. If it's one of the clutch type "lockers", then that is a bad symptom. If it is a viscous coupling or a Torsen type, then what you are seeing is expected behavior. Torsen stands for "Torque Sensing" and if one wheel completely loses traction, then the other can't be made to spin. That is why you more commonly see selectable lockers, spools and the clutch type limited slip in off road vehicles.
From the "How stuff works" website;
A quick primer on differentials is located at; http://www.howstuffworks.com/differential.htm
At best, a differential can supply equal torque to both sides, that is a locker. At worst, all the torque goes to the wheel with the least traction, that is an open diff. All limited slip systems are somewhere in between.

However, if one set of wheels loses traction completely, the Torsen differential will be unable to supply any torque to the other set of wheels. The bias ratio determines how much torque can be transferred, and five times zero is zero.

As per Rob, it depends on the type of LSD you have. Do you know what type of LSD you have, by chance?
As far as I know (and as per howstuffworks.com) you can have greater than equal torque to each side with Torsen diffs and the way they bind. That's one of the reasons that Torsen differentials are considered superior.

Doh!
I will edit that post so I don't leave the incorrect information in the archives.

Then retire in the lap of luxury to that ocean front property in Arizona you bought and enjoy your beautiful view of the Brooklyn Bridge.
That will give you lots of time to install this Pringle's can in your engine for a 300 horsepower gain and 60 miles to the gallon.
You'll thank me for this tip, someday...

I am trying to find out what type of LSD it is.
It doesn't even mention an LSD in the owners books.
But there is a sticker on the diff "Use LSD oil only"
I'll keep you posted
Thanks for all the help
