What is the advantage of all wheel drive?

It's better than front wheel drive and even better if there is limited slip and very good if it has a mid differential lock. Manufactures have stopped installing differential locks because the drivers were activating them while a wheel was spinning and thus the splines would shear off the locking mechanism and render any 4wd useless.

How do you know if your Ford is all wheel drive?

It normally would have a 4wd written on the vehicle somewhere. To be sure just look under the front. If you see a differential it is 4wd. If no differential then it is not.

On the 1997 Ford F150, the differential could be in both the front and rear. From 1997 and on Ford used two different axles. Your truck could either have the 8.8 or 9.75 differential. If you have a rear differential you would need to lower your spare tire to have access to it.

What is the front differential vacuum actuator lines layout for a 1984 Chevrolet S series?

The actuator is a vacuum driven relay that locks the front hubs when the 4 wheel drive is engaged. Failure of this part would result in the transfer case being engaged and sending power through the front shaft but the front tires would not have torque. This is a failure prone form of auto locking hubs. Used on late model Chevys Dodges and Some Cherokees. Alternatives would be a constantly locked hub set up, which consequently reduces fuel millage. Or, a manual lock system such as that used on Fords for decades.

What would cause locking up in the rear of a 2004 dodge Dakota?

A hung brake, a bad wheel bearing, a bent axle, seized gears in the differential. Or, probably rarely, faulty traction control or ABS (if equipped).

Why would a 1995 corvette front wheels lock up?


Does a stock 1977 dodge power wagon have all time four wheel drive or is it suppossed to have hub locks on the wheels?

A stock half-ton 1977 Dodge Power Wagon should have an NP203 transfer case and a Spicer model 44 front axle. The NP203 is a full-time transfer case with a locking differential in it to allow for a selection between "four-wheel drive" and "all-wheel drive". In other words it would send equal power to the front and rear axles, or divide power between the two axles based on driving conditions. The Spicer 44 front axle is not suppose to have manual locking hubs on it due to the fact that the NP203 transfer case is always sending power to the front axle.
