Plain and simple
<font color=blue>You could pull the cover and look, or you could jack up one wheel and try to spin the other. However, if the posi is worn, this will not work</font color=blue>

Hook a tow strap around a tree and use throttle until you spin the rear tires. If both rear tires spin=possi. If only one=not

I hear if you jack both tires up and spin one if the other tire spins the same direction it is posi if it turns opposite it is limited slip. Is this right???
take your diff cover off and look at the carrier.. If you see a mostly closed piece of iron with springs and clutches, then you have a Gov-lok...
If you open it up and you see the carrier with two large open spaces in it and you can see (4) spider gears and the center pin, then it is an open carrier...
I am assuming you are talking about a factory rearend..

What are spider gears ?
Which ones are on the top and bottom ?
Spider gears are on the inside of the carrier. They are what creates the 'differential' effect of the rear end. My carrier is open and some of the spider gears fell out when I took out the cross shaft to remove my axles. I was able to see what locations they came out of and had no problem getting them back in. I did notice that they had some shims underneath and I was sure to get those back in.
