Help to clarify "limited slip"
Hey Guys,
I have an understanding of what "limited slip" is that I am now unsure if correct.
The way I've understood LS is that, with regards to a 4x4, a NON-LS truck will only supply power to one wheel in the rear and one wheel in the front. (essentially a "2WD" truck)
Likewise a 4x4 with LS will supply power to all 4 wheels.
Is this correct?
I know this may seem like a basic question but I've read some things lately that casue me to question my definition.
Thanks,
CMOS

I dont know alot about it in technical terms but my 2 cents...
An open differential (NON-LS) supplies power to one wheel, but the amount of torque that the drive wheel can actualy use is also supplied to the no drive wheel... I'm pretty sure this is correct. I know I have gotten an open diff. truck stuck and have both wheels spin in the mud.
The LS when one wheel slips it has spide gears, cone gears, enguage and supply power to both wheels. But I have also pulled an LS 2wd truck out of mud with my 4x4 Open. And the LS on the 04 f150 2wd was not engaging properly and only one wheel would spin. I have heard people say if u lightly mash the ebrake that will get both wheels to cetch on the LS.
I think it is "How Stuff Works.com" has a great great page on differentials.

In an non-limited slip 4x4 torque is supplied to all four wheels, until one or more loses traction. If one rear wheel loses traction it will spin and the other will not. It is possible for both tires on one axle to lose traction and both will spin even if it is an open diff.
With limited slip there is a clutch in the rear axle that will limit how much the tire without traction can spin. That will have the effect of sending the torque to the tire that still has traction.
No stock truck has a limited slip on the front axle because all automakers want their customers to be able to steer their trucks.

Limited slip means that there is a limited amount of torque (usually 20 Ft Lb.) sent to a non-slipping wheel. If the truck requires more to move it than the limited amount of torque to the non-slipping wheel then the clutches will slip and the spinning wheel will continue to spin.

Bronco IIs had them. The 83-84 Ranger was suppose to have them, never seen them though.
I thought Hummers have them (soft locker).
Internationals have real Detroit lockers.
New Wrangler Rubicon has selectable lockers front and rear.
etc.
