Neat video of open diff vs 25% lock diff vs variable diff

My expedition works like crap in mud. It has an open diff. Our bronco has a limited slip and even in 2wd it has no problems doing through mud with hardly any slip.

ratcheting locker for the win, i could almost own a 2wd truck if i had one in teh back. I almost never use 4wheel now unless I am truly offroading. Of course modified LS are good too. Extra clutch pack and springs. Or even torsion differentials.

Of course I don't want people I drive around in the winter on the highways having these devices as there would be even more accidents.
 
That is sweat, though Jeep had a similar system over 35 years ago called Quadra-Trac.
I never really liked AMC/Jeep much but a friend of mine had a 1974 Jeep Wagoneer that could not be stopped. We live in the snow belt and a group of us had 4x4 trucks setup for mudding in the summer and snow in the winter. My friends Jeep had some engine work done but was otherwise stock including street tires. He could just drive circles around all the GM, Ford and Dodge trucks no matter what the conditions were, excluding under water. So a good 4x4 system makes all the difference in the world.
 
I owned a '93 Dodge Dakota with an open diff, and a '94 Dodge Dakota with a limited slip diff, and I love the limited slip diff in the '94. My '93 had a V6 and the '94 has the V8. The '93 would have been scary with a V8 in the rain.
 
Actually a open diff is easier to drive than a clutch type diff in the rain or on ice.
With a clutch diff the rear is all over the place. If your 93 with the open diff had a V-8 in it the right rear tire would be bald in a week.

I few years ago I worked on a 2 wheel drive Dakota with a magnum V-8 and a limited slip diff in it. It was impossible not to light the tires up when starting out. I was trying to pull the truck in the shop and was lighting up the tires. The owner of the truck was watching me and laughing his ass off.
