How 4WD (4x4 - Four Wheel Drive) Works - 2H, 4H, 4L, LSD, Centre Diff, Diff Locks, Traction Control

*Please note: In this video I have incorrectly mentioned that Torque is distributed/split based on wheel resistance. In reality, in an open differential Torque is split evenly 50%-50% to each axle regardless of wheel resistance. However, Power is split based on wheel resistance in an open differential, not Torque. Power = Torque x Angular Velocity. Therefore, in an open differential, if a wheel is in the air and freely spinning, the other wheel which isn't rotating isn't transmitting any Power (as Angular Velocity = 0, but Torque is still present). Watch out for a future video which further clarifies this.

Man this is one hell of a well made video, I have been doing offloading for over 8 years now & even made it to advance level riding with the big boys but honestly this is the first time I actually understood what is going on under the hood, why & how to possibly deal with it. Although I watch many videos about the topic, this by far is the most informative, comprehensive and simple to follow one. Thanks a million.

This video is where failed car advertisement scenes end up. Very well done video!

I swear I NEVER comment on videos but I had to give a shout out for this brilliant explanation. I’m new to 4WD and this is the first decent explanation I’ve found. The simple graphics helped one hell of a lot too. Can’t thank you enough.

One of the best instructiona and educational videos I have heard in a long time and the honesty in self correction is appreciated. Thank you Sir for your service. Wish we had more people like you.

The part when you talked about front locking hubs clarified things for me. Thank you!

Best video I have ever seen on how the 4x4 drive systems work. You not only have a very good understanding of how these systems function, but you are also very good at communicating your knowledge.

I have never driven any 4 wheeled vehicle, yet this video is informative and very easy to understand for me, you have explained it perfectly with animated diagrams and real sample drives!! well done and thank you!!

Clear, precise and easy to understand because of your excellent delivery and accompanying videos and animations. Well done.

MY ISUZU 300 4X4 TRUCK IS PART TIME WITH LSD WITH MANUAL HUBS THANK YOU FOR DETAIL VIDEO AS GREAT WATCHING

My goodness, a channel that actually explains and shows examples of when to use 4 low or 4 high. Gotta see an example if you’ve never done off-roading. Thx

I have a pretty annoying habit of needing to have some level of technical understanding fir anything I'm attracted to. I bought my first 4WD vehicle and needed to answer many questions: What is a center diff? Hiw does 4L differ from 4H? Hell, what is a diff? This video eloquently strings together many concepts in a manner that enables novices ti obtain some elementary understanding of their machines. I was lost trying to find a comprehensive video till I stumbled on this. Much obliged!

Great video, mate ! This is the most comprehensive panorama of the topic I've ever seen. As a follow-up, you might want to cover the gearing system in the wheel hubs of Unimogs and Hummers. My first offroad fun was in 1974 in Ethiopia driving a Gaz, a robust Russian military jeep: side-valve engine, 3 forward gears, part-time 4WD with high and low ratios, + freewheeling hubs. I had incredible adventures especially in the Danakil Desert.

I am definitely going to have to watch this a few times to grasp all of it. This guy should be a teacher

This video is the best thing one can ever get on these topics. Cheers mate

Excellent video. Professionally done. All the important information you need to know with visual aids and real life examples without annoying background music!

Nice video. Btw your voice is so soothing that I slept half way through and had to re watch the video again !

a simple and easy way to understand of 4x4 use and diffrential! thanks mate.

i have watched a lot of your tube videos regarding this subject but you are the Master everything well understood thanks Pal .

Ive been having 4x4 for years, yet i did not know this much knowledge. Thank you for the explanation.
