Four Wheel Drive: When engaged, the power is applied to all four wheels.
Low: Some four wheel drive systems have a high and low setting.
at Low setting speed is compromised for higher torque and vice versa.
That is an old style of saying that a wheel is low offset rear w/drive like a old car or hi offset front w/drive like a new honda civic.
Four wheel drive high is used for everyday purposes such as driving on a snow packed road or light off roading. Four wheel drive low is for special circumstances such as getting out of deep mud and snow or towing a trailer up a steep hill. Four wheel drive should never be used on bare, dry pavement. Use two wheel drive in this circumstance. You will completely ruin your transfer case by using four wheel drive on pavement.
That would be the gear ratio in the transfur case. low is for pulling HEAVY stuff a VERY SHORT DISTANCE ONLY. 4 high is for road driving in snow and off road 4 wheeling.
As it turns out, "all-wheel drive" refers to vehicles that have permanently engaged or automatically engaging four-wheel-drive capability. "Four-wheel drive" implies the vehicle has manually engaging, temporary four-wheel drive. Your confusion is justified -- the auto industry, in their infinite wisdom, created these seemingly interchangeable terms. The major difference is that most "true" four-wheel-drive vehicles also have a "transfer case" that can provide both a "high range" and a "low range" gear ratio from the engine to the wheels. High is used for slippery conditions on the road, while low is exclusively for off-road use.
I have always understood that an allwheel drive car is always using all four wheels under power, while a 4 wheel drive car can be selected for either 2 or 4 wheel drive in a high or low ratio setting. Actually, "All Wheel Drive" delivers power to either the front or rear wheels, depending on which has the least resistance. Power is transferred between front & rear according to the surface traction. Power is never delivered to both front & rear at the same time, except with symmetrical AWD such as Subaru.
True 4 wheel drive has a dedicated low range gear. There are stick shift cars with full time all wheel drive that apply power to all 4 wheels all the time, just like a 4 wheel drive; however, they do not have the dedicated low range gear found on off road 4 wheel drive vehicles and are therefore less capable under those conditions. The average road driver though would not notice a performance difference between the two. The subaru impreza and subaru legacy are cars that have a stick shift and full time all wheel drive. No doubt there are others.
No , the 5.0 liter came as 2 wheel drive or all wheel drive with no low range
put the shifter in 2h which stands for 2 wheel drive high..................4h stands for 4 wheel drive high for city streets and highway,,,,,, 4 low which is 4 wheel drive low,,not used often,is for low low speeds about 5 to 10 mph at most....n on shifter is neutral,,,take care........dont run vehicle if its a 4 wheel drive in any 4 wheel drive gear on dry pavement as this can do damage over time and is not good for many parts of the 4 wheel drive system.....take care...... i am a journeyman mechanic for near 35 years....merry christmas
The basic concept is that 4x4 runs 4 wheels when you need it. All wheel drive runs them all the time regardless. The difference is, with 4x4 you get the option of high and low gears in 4x4, and not the same way with all wheel drive. "All Wheel Drive" vehicles do not run all 4 wheels at the same time. In low traction situations, the power is transferred from back wheels to front wheels where the engine weight is, when wheel spillage is detected. But "AWD" never delivers power to all 4 wheels at the same time. 4WD vehicles can power all 4 wheels at the same time, assuming that both ends are equipped with limited-slip diffs., or at least to three wheels (both rear & 1 front) if equipped with a rear diff locker only.

If it has 4-wheel drive you would see controls on the dash to engage 2-wheel high, 4-wheel high or 4-wheel low.
If your in 4-wheel drive HIGH, Then 65 to 70 will be just fine. But 4-wheel drive LOW is about 10 miles per hour AT TOPS. NO FASTER.
You have to be stopped with the transmission in neutral when you shift in or out of low 4 wheel drive. Park doesn't work as neutral. When you push the rocker switch up for high 4 wheel drive once you will be in high 4 wheel drive, push it again for high 2 wheel drive, you can shift between high 2 and 4 wheel drive while you are driving.
