Having an centersection that changes drive force from a spinning wheel to a non-spinning wheel is as good as it gets.
...as long as you keep of the throttle and don't get BOTH spinning. Then it's as bad as it gets. It's also the point of this whole thread. I wanted to hear from guys who use them on the highway (NOT off road) about how much problem they have with both sides spinning out.
Limited slip diffs have been around forever. I'll bet more people have driven vehicles that didn't know it was equipped with one than people that did. As I said in an earlier post,you really don't know what it's like to have a limited slip until you've driven a vehicle w/o one. Even my wife says she doesn't like not having one in our Cherokee. They're that good.
How does limited slip work?
Clutch packs inside the differential create additional resistance. This resistance is always present. It is called preload. So, whenever one side wants to start rotating faster than the other, this resistance (preload), in addition to the traction present at the wheel has to be overcome before a tire can spin.
Traction and preload have to be high enough to keep tires from spinning but low enough to still allow tires to rotate at different speeds in a turn. Since the preload has to be kept low enough to allow safe cornering the slowing effect on wheels that want to spin is marginal. It works in easy off-road conditions and on mildly slippery roads. For serious off-road use and very slippery roads (snow, ice) limited slip is not powerful enough. It limits slip but it does not prevent it completely
