4 wheel drive won't work on 2001 GMC Jimmy?
There is a cable for the front differential. One end goes to the front differential, one end goes to a vacuum actuator under the battery. That is what most commonly is wrong with those vehicles.
Does a 2001 JEEP Wrangler Sport have a limited slip differential?
They can come either with the limited slip or a open differential. If you cant find any of the original paper work there are two ways to find out. One is to take the VIN number to a dealer and ask them if it does. Another way is to place one rear wheel in a way so that it doesnt have any traction at all. If it has an open differential it will just spin and the Jeep will not move forward. The limited slip will give some traction to the other wheel and Jeep will creep forward. Good Luck.
4x4 s10 front differential interchange between 1996 and 2000?
As long as they are the same gear ratio they interchange also All wheel drive astro vans front diff will work
Your 4 wheel drive does not work and the light does not go on why is this?
Most 4WD vehicles use automatically locking hubs. By engaging 4WD, a vacuum is formed in the front wheel hubs causing them to lock up into the front differential/transaxle so they can receive power through the transmission. If the seals are leaking, then the vacuum will not form and 4WD will not work. As for the light not working, I suspect that different models use the 4WD indicator light on the console to either identify when the front differential/transaxle is engaged or when the front wheels are actually engaged. Not having the light on when attempting to engage 4WD can either mean problems with the front locking hub mechanisms or the front differential.
How does an electronic differential in automobiles work?
In conventional road vehicles an electronic differential is usually a mechanical differential that uses an onboard computer to directly control and adjust the torque split and difference in wheel speed across the axle. This is acheived by electronic actuators engaing clutch packs and locking mechanisms to acheive the desired traction condition. It is esentially a computer controlled LSD and differential lock in one. This means the computer can calculate the optimal torque split and actively vary it on the fly. In electric vehicles with separate motors driving each wheel, an electronic differential is simply a computer that controls the wheel speed of the inside and outside wheels based on the steering wheel angle, to acheive the same effect as a normal mechanical differential.
Why won't the 4 wheel drive on my 86 Jeep wagoneer work I was in 4 wheel and the next thing i new i was in 2 wheel any ideas?
either the vacuum hose came off the selector switch or the nipple rotted off the air motor on the front differential.
What is the average cost to replace the front differential on a 2006 Xterra?
It will cost you close to $2,000 to have your front differential replaced on this vehicle. The amount will vary depending upon who does the work for you.Ê
How do you fix traction control on a Ford Windstar?
Depends on what is wrong with it. My traction control did not work as long as there was a problem with one of the ABS wheel sensors - the two functions are tightly integrated.
Why does the truck jerk while driving in four wheel drive?
Because as you turn corners the path and distance each wheel actually goes varies. In normal 2 wheel drive this difference in distance travelled by the rear drive wheels is accounted for by the action of the rear differential. But some/many four wheel drive vehicles do not have an equivalent differential type action between front and rear wheels. (I drove Suzuki Samurais, I don't know about Chevy pickups specifically.) The jerking and lurching can be intensified if there are "LOCKERS" installed...devices that work in the differential to limit wheel spin on one side when the other side still has traction. When driving in mud, sand, snow, or other loose surfaces this is not usually a concern, as any slippage will be between the tires and the surface being driven on. But if driving on good solid traction surfaces, such as clear dry concrete or blacktop, the tires are less likely to skid on the surface, so things get bound up and jerking/bouncing can result. This is why on older more primitive 4x4's, one should never engage the 4 wheel drive if not on loose surfaces. My brother once broke gear teeth in a 1969 Jeep by leaving it in 4 wheel drive on dry pavement. The tires had too much traction and the increased strain as a corner was turned was strong enough to break the gears in either the differential or transfer case (I forget which.). Many modern 4 wheel drive vehicles do not truly lock the differentials or front to rear gearing, and are more tolerent of driving in 4 wheel drive on sound pavement.
The four wheel drive was engaged during dry highway driving and now it doesn't work. the tc engages but the front wheels won't turn?
There is some sort of vacuum cylinder or diaphragm on the front differential that engages it when you are in four wheel drive, that is probably the problem, I don't think driving it on dry pavement caused the problem.
What kind of skid occurs when the brakes are applied so hard that the front or rear wheels lose traction?
For rear drive cars - it's called a fishtail. You brakes work better on the front. Anybody who sailed over the handlebars when braking just the front wheel on a bike is called a head plant, (ouch)
Will a front differential work as a rear differential on a Honda 450 ATV?
I'm sure one with the right tools could fabricate it to work.... But for the general, the answer would be NO. The front is a different type of gear system. It also used different axles and mounts differently.
