fx4 limited slip not working properly?

anyone else with the fx4 package notice the limited slip in the rear rarely(if ever) locks up and spins both? i've been noticing more and more that only one will grab and no matter what i do ( wether it be on ice, snow, mud or a brake torq rolling into it easy or flooring it) it rarely will grab both..... so my question is WHAT THE HELL DID I BUY AN FX4 FOR IF IT WONT LIMIT THE SLIP ON A LIMITED SLIP?

It does just what it says, limites slip. Not locking. There was a commerical on T.V. not long ago that showed the difference. A locker put down something like 1000 ft/lbs of force. Our limited slip put down around 100 ft/lbs.
Don't quote me on the numbers, but it was a big difference.

Mine does the same when the diff is cold. Do a brake torque and heat it up and watch it, it'll lock in. My dad done his so bad, they stuck locked in, until it cooled back down and freed up. I believe that's why they work when your towing, they get heated up.

I NOTICED IT ALSO I HAD 1 TIRE ON THE ICE IN MY DRIVEWAY AND ONE ON THE BLACK TOP AND I WAS STUCK! I BROUGHT IT TO THE STEALER FOR AN OIL CHANGE AND TOLD THEM ABOUT IT! THEY SAID EVERYTHING WAS NORMAL THEY TRIED TO GIVE ME A BS STORY. I SAID WHY DID I SPEND $300. FOR A LIMITED SLIP DIFFERENTAL A REGULAR ONE WOULD DO THAT. ON MY NEXT OIL CHANGE I WILL TRY A DIFFERENT DEALER SEE WHAT THEY SAY. OTHERWISE I WANT MY $300. BACK!!
I TRIED SPINNING THE TIRE FASTER TO HEAT IT UP, AND IT DIDN'T EVENT TRY TO ENGAGE. BUT IF YOU STEP ON THE GAS IN THE DIRT IT WILL SPIN BOTH TIRES! I DONT GET IT?
