Check the linkage. If it's good your getting due for some tranny work.
If you mean limited slip, and when you do a burn out and only one is spinning that is normal
It kicks in when slip is detected. Four wheel drive is not on all the time, only when needed.
you probably didnt have it engaged properly. that's happened to me on my friends bronco.
For the drive wheels on most cars - the rear wheels on a rear-wheel drive car, or the front wheels on a front-wheel drive car. There is a "limited slip differental", a set of gears connected to the driveshaft and axles. For the non-driven wheels on your car -- the front wheels on a rear-wheel drive car, the back wheels on a front-wheel drive car -- this is not an issue. There is no connection between them, so they spin independently. But the driven wheels are linked together so that a single engine and transmission can turn both wheels. If your car did not have a differential, the wheels would have to be locked together, forced to spin at the same speed. This would make turning difficult and hard on your car: For the car to be able to turn, one tire would have to slip. With modern tires and concrete roads, a great deal of force is required to make a tire slip. That force would have to be transmitted through the axle from one wheel to another.
Four wheel drive means that the front and rear driveshafts are locked in to rotate at the same speed constantly when engaged. All wheel drive depends on the system... on a traditional system, the other axle will engage when slip in detected in the powered axle. On a modern, computerized, asymmetrical AWD drive system, the transmission is attached to a differential which is computer controlled and applies power where it is needed. Additionally, the axle differentials are electronically controlled and can be locked and unlocked as needed.
I would put them in the back, that's where you're still most likely to slip.
The question was I have a 1997 Ford 4 wheel drive why is it up in the air on a lift when the truck is in two wheel drive the rear end acts like a limited slip where one wheel turns one way in the other wheel turns the other way but when you lock it in 4 wheel drive the switch on the inside and put it in 4 wheel drive for some mysterious reason the back becomes posi Trac we're both wheels turn in the same direction why is that
a blown transmission
What would make my transmission slip on a Dodge truck when turning left
the purpose of the slip yoke is to allow for movement over bumps and different terrain. if there was no give ,you would constantly be trashing the driveshaft or transmission
You can't do it manually. The operation is entirely controlled by the vehicle's on-board computer which - when it senses wheel-slip from the front drive-wheels - automatically sends a signal that engages the drive shaft to the rear wheels, placing it in all-wheel drive mode.
