A Limmited Slip Differential Question

As posted multiple times above, pop the cover. The answers are on the other side. And you will be able to put fresh fluid in it. Just don't use that synthetic crap.
If its open, put a powertrax lock-right in it. Problem solved.
My gm corporate 14 bolt in my diesel has a (supposed) gov-loc lsd that only locks up the wheels when one wheel spins fast enough to "throw out" the weights. It doesn't seem to work well at all.
