4WD Low vs 4WD High | What is the Difference? **Heavy Duty Mechanic Explains**

thinking about having to drive that truck over that pit gives me anxiety. i guess you gotta be used to it to be comfortable.

greetings from Florence Italy good evening I have a legitimate question if possible you can give me the correct answer (good morning can you tell me why many owners of 4x4 par time vehicles are called 4wd low in English? wet asphalt when it rains they insert the 4x4 hello the fast 4x4 since many 4x4 vehicles do not have a center differential??)

use of 4x4 on off-road and paved roads in the presence of rain and wet asphalt

I kept staring on how big the pit is

I would like your videos better if you spoke English, mph not kilometers, F. degrees, not Cealceious. Inches not mm. Thanks.

Bro that ws excellent explanation👍

Passenger side is on the GROUND ....LOOK

Great video as always brother. Quick question, I have a 93 trooper with aisin manual locking hubs. Is it okay to use 4L with the hubs unlocked? I find it easier to drive steep hills using 4L but 4x4 are not necessary on pavement right? Also 4x4 is not r commended on paved road. So i was wondering if i can use 4L in 4x2 mode (hubs unlocked). Will i break anything? Thank you

Does that mean that you can drive on paved roads in 4Hi as long as your axles are not locked? Total novice here.

I have used 2WD Low. I was stuck in bumper to bumper traffic, going 2 mph for a few miles. The truck had a manual transmission so I just put it in 2wd low, popped the clutch and just coasted at idle for a few miles. My left leg loved me.

Ben hardys lost bro?😂

Well said

Should i use 4wd high or low in mud ? also when im stuck in mud ?

Do vid on jeep truck on canyon or Colorado on Tacoma on ranger

why would you buy a Ram 2500 on gasser? What's wrong with Cummins Diesel?

Can someone please explain in short ? And what would I use for pulling people out of ditches? 4wd low w/ tow and haul and what so I ise in snow

Great video. I like Toyota's Crawl Control. I know that does not have much to do with your video here.

What is 4wd lock?

Great video. You just made a new fan. "2 wheel Low" was rather common back in the day. We would just shift into Low and not get out and lock the hubs. It worked great for driving around the pasture. Also, I have A 2017 Ford 4x4. It certainly has electronics past the tranfer case and uses traction control technology to simulate locked axles in 4 High. However, that traction control turns off in 4 Low. Consequently, I have been able to navigate tricky situations in 4 High with traction control that I could not do in 4 Low. Not sure why Ford wont give traction control in 4 low but there have been plenty of times I wish I had it.

When putting an order in for a 23 ram 1500 Limited, I can choose anti-spin, or E locker, or neither, they say with the anti-spin it’s always on, but if I don’t choose anything, what does it have? just the 4wd? If I select 4wd hi, doesn’t that split the power evenly front to rear 50/50? Is the options for anti-slip or a locker just an added option? It doesn’t take anything away from the normal 4wd function?

Cheers, thanks for the informative vid! Also, that is a nice truck👍🏼😊

I love how this guy just throws up a physics equation like everyone can just look at it and understand it in the 2 seconds it was on screen

Trying to understand, when I put my Ram 2500 DIesel in 4WD High only one wheel on each axle has power to it, or the same for 4WD Low. DIesel Rams are Heavy Birds, My planis to build and Overlander to take trips with and Boondock or Disperse Camp in places like MOAB and the like. DUe to the heavy truck I know the least bit of mud would be problematic. I am planning on RUnning 37" Tires or 17" RIms and regearing to 4.56 Ratio from 3.73 to compensate for that and thought that throwing lockers in at that time made sense for peace of mind. Am I on the right track, I really do not want to lose the LSD for Highway driving but I think I may have to sacrifice it and go with F/R Air lockers your thoughts???

what kind of loser gets a 2500 NON DIESEL pick up

I love my 2010 power wagon

Stopped watching when I saw a recovery strap on a trailer ball.

My current truck is the first 4WD I have owned so I am still learning stuff. I only have gone off road a couple of times and I have used it to get through snow a couple of times.

What about vehicles with "Limited Slip" rear differentials or vehicles with a limited slip transfer case differential?

A good 4wd low is a HUGE deal. My transfer case is 2.92... that means it basically TRIPLES the torque! More torque will help you keep momentum. Keeping momentum, especially at low speeds, will help prevent getting stuck.

If it was just about going slow , a lot of that could be achieved via throttle controller these days because at ultra low throttle , you can sort of stay below the torque converter stall speed. That ALSO makes a huge difference.

If it had eld or bld it would put 100% power to 1 tire

Great explanation. Thank you

Todays modern trucks and SUW have Auto tranys and the gear ratio is hight 1 or above. Older Standard Tranys had a 1st gear under 1, and powerfull enough not to need 2 Low. My 1984 FJ60 will climb a wall in 1st Gear as its under 1 ratio. I usualy use 2 nd Gear to take off on flat ground. 4 HI often for beach sand. 4 Low years ago to pull a stump and pull a car parked in my parking spot

Um. Just an observation. But the front right tires were still on the ground.

Why is it so hard to turn in four wheel drive? My truck hates it

14 minutes??😅

The wheels do not turn once for every time the crank rotates once.
You forgot the rear end ratio.

MY old 79 k15 GMC half ton full time 4x4 had 2 low on it. Now I have a 2017 f350 which I have to unlock the hubs to achieve this. This is very useful when pulling a utility or boat trailer in rough country roads with sharp turns and plenty of boulders. The low gear lets you crawl over the boulders, and you can turn very sharp without the 4x4 system making your front-end bounce around tight corners. You have greater control. Of your speed over rough country with more torque that lets you crawl over the rocks without having to put the pedal to the metal and jumping over Bolders at higher speeds. and without the 4x4 engage you don't bind up your front end in extreme tight corners.

If you don’t know the difference, please never drive anything but a small car

Lunch box locker , front.
Cable locker, rear .

BASICALLY 4 LOW FOR BETTER TIRE BITE. 4 HIGH FOR WET REGULAR DRIVING CITY SPEED?

Sounds like fraud to me. If they advertise it's 4 wheel drive you should get 4 wheel drive.

Power is not split 50/50 with a 4wd part time transfer case. Power is torque over time and since rpm (time) is fixed torque would have to be equal.

Torque requires resistance. If you have no resistance you can’t generate torque. Just screw something into your drywall and you’ll experience it. It’ll become harder and build more torque until it can no longer offer resistance and easily spin.

Same thing with the wheels gripping the ground.

Lockers bias torque to the wheels with the most traction. Ie lift a wheel it can no longer generate torque, so 100% of the torque must flow through the wheel on the ground.

50/50 means equal means both have the same. Open diffs are 50/50 which is why you lose traction on one wheel the opposite wheel can no longer generate torque and both wheels receive no torque.

I prefer my 4x4 lock on my ram

Many tks!, Alex, for the super clear explanation. No one else explained this clearer.

Mate you’ve just gotta get to the pount

DIFF-LOCKs ..... To both axles ..... Really 4WD mode then ....

When I tow my 40’ 5th wheel, I do put the truck in 4 low when I go up/down my long steep ass driveway. Very steep and very long. Just seems to save the brakes and the torque converter.
