There's a way to find out without opening the cover.Ya I have no idea if it has the g80. I’m going to take it to a shop and see what they say. I will be getting the transmission and transfer case rebuilt then have the rear end looked at. I noticed the transmission cross brace was missing 2 nuts and it was hanging. Luckily the other side didn’t fall off. But now my tranny and transfer case leaking. ![]()
Lift the whole rear end off the ground and release the parking brake.
Spin one side and see what happens.
If you have clutch type limited slip both tires will turn together.
If it's open the other side will turn the opposite way.
If you have a g80 spin it a few turns as fast as you can by hand after a couple of turn the centrifugal piece will lock it and the other side will start spinning with it.
I used to do this at the junk yard to know what I am buying.
