You differentials on each axle are either open, limited slip, or locking. Open is most common stock, it means that the pair of wheels on one axle are connected together at the differential by another set of gears, "spider gears", that allow one wheel to travel faster than the other on turns. This set up also allows one wheel to spin, and the other to just sit there, hence you are stuck. A limited slip has either clutches or cones in the dif that are pre set to allow some variance between the two wheel speeds, but when one is spinning the other will get some traction, maybe keep you moving. Limited Slip are also known as "posi" this from positraction, a particular brand name. A locker in your diff will lock both wheels together, both will turn even if one is in the air, but will "dissengage" when going around corners to allow for different wheel travel in a turn. The most common locker is a Detroit. Lockers are known for their bad manners on the road, like noise when disengaging, and jerking when engaging. There is a big difference of opinion over which is best, rock crawlers like lockers, mud guys tend to like LS's or lockers, and some old purists say open differentials plus driving skill is the way to go. I tend to prefer LS because I would rather get stuck than break an axle. The best of all worlds is avsilable in an ARB air locking diff, or an Ox locker, which is a cable operated locking mech. You drive on the street with it "open", and when you need the traction you lock it. But you pay a price, about 800 bucks or more for the locker. I have a suburban, a ford f100, and a Grand Wagoneer. But...I am planning a mopar 413 install in the jeep. I like the size and sturdiness of the full size Jeeps, but the amc 360 sucks, I hate everything about it. Dodge has some good choices, older ramcharger, or what about the newer jeep stuff, it's chrysler after all.
