When to use low range in your 4WD 

Hashem Eshanouq silly nillybup that hill bill

Not completely. 2H is for normal street paved. 4H is for snow, gravel, Texas rain, or other conditions with limited traction. 4L is for rock crawling, steep off-road inclines (up or down), deep mud, pulling stumps, or other extreme off-road conditions. For 2 wheel drive vs 4 wheel drive, the key thing to remember is that it needs to be slippery to use 4 wheel drive. When you turn, your front wheels and rear wheels travel different distances, so the wheels need to turn at different speeds. In a 4x4 in 4H or 4L, the front and rear axles are locked together. So if you use 4 wheel drive in conditions that are not slippery, you can cause excess wear or even damage the transmission. On gravel roads, snow, or icy conditions, I will use 4H. On pavement in heavy rain, I will drive down the road in 4H, but if I need to make a sharp turn, will take it slow in 2H. In low gear - 4L or 2L (uncommon now, but some trucks have 2L available) - the gearing is much lower than the high gears. It's like your gears change from 1 - 6 to 0.1 - 0.6. So you get lots of torque, finer control over your speed, and more engine braking - but need to keep it very slow, or you can damage the engine or transmission.

Tire deflater, stupid.

Thank you, Dr. Indy Debauchery.

Without being an ass hole like the previous bloke... it is a cordless tire pump, but can also deflate ^_^ plenty of different brands!

@@indydebauchery5732 What is wrong with you?

But they last far longer than any car

Its on the bottom of your central panel, somewhere around the central cup holder.

If u have an older model prado, the 4 wheel drive is in a stick shift sort of shape, on the top left of the gear box

Prados are AWD most of the time. They won't have a 2H. It's just 4H and 4L. He does mention that in the video and if you look at the selector switch, it'll only have those two options.

Thanks for asking, I'm scrolling through the comments for this very question / answer...

Disconnect the drive shaft that goes to your real wheels.

Agreed. I wouldn’t bother putting the car in 4L for that stuff.

4lo both rear and center Locked

Best for sand driving

Based on my understanding, when you put your car in low range, you are using different gear ratios. I.e, you are in fact using different gears than those 8 gears you mentioned. Your car's transfer case includes more than those 8 gears you know of. Check it here: en.wikipedia.org/wiki/Transfer_case

Like aref said below, there is some additional gearing in the transfer case on a 4wd. It is the third that changes when you move to 4l this changing the ratio of your normal gears when in this position. Kinda like a push bike. The transfer case is like changingyour front gears, as you still use the same gears on the back. Hope that makes sense

Here's the simplest way to explain it to you the transmission gear stay the same the transfer case has a high speed gear ratio and a very low speed gear ratio like a tractor so that's what happens when you're in low you're transferring transfer case is now geared down so you go through all your 8 years but you're doing them at a much lower gear ratio in the transfer case

To put it really simply, low range revs your engine higher at lower speeds, which gives you much more torque for the same grip that your tyres give you. You'd know that high torque allows your engine to pull more weight, so keeping the vehicle weight the same but increasing torque means it'll pull itself much more easily on extreme angles like rocks, steep inclines, etc.

Paul Anderson just think of this. A transfer case is like a secondary transmission. With high and low range. With in Low range gear reduction happens. I hope this helps you grasp the idea.
