I like how quickly he described everything. He kept it concise and to the point. And the little humor makes it even better. Nice vid 👍🏻

I know how a diff works but clicked because I am always curious to find new videos to show my kids or send to people who need to learn. This is; by far, one of the most well spoken and concise automotive videos I've ever seen. Short, to the point, clever and CLEAR. Outstanding video.

Very concise, yet detailed at the same time. Excellent video for learning and revision any time one's memory needs refreshing points. Differential consists of a set of gears that operate together on the drive wheel of the vehicles to ensure that the inner and outer wheels of a vehicle rotate at different speeds in the same period of time, as they should, when a vehicle is making a turn, due to the difference in the distances covered by the wheels when a vehicle is turning. The purposes of the different gears that make up the differential assembly are easy to understand and remember. Knowing and remember about the differential makes one know and remember that the the left and right wheels do not rotate on a single solid shaft, but that the differential assembly casing is what connects them, and that the right and left wheel shafts actually terminate in gears.

I have watched dozens of KZfaq tutorials on how the various parts of a vehicle works. Each video I watch, someone explains a tiny thing just a little better than someone else. I thought I knew how a limited slip differential worked, but was always unsure why it was called "limited slip". Today, I learned it is the clutch pack that slips a bit allowing differential speeds between the axles, thus giving its name. And this is coming from someone who has front and rear locking differentials on a Tacoma.

Excellent concise breakdown! Truly a mechanical marvel! The level of undeviating engineering precision is unreal! And we all take it for granted every day!

“Special Press” love it!

5 years as a auto tech for a big company that makes tiny engines, and I think your video explained diffs better then my online training did. Spider gears are way easier to comprehend once you’ve seen em

I love the way he explaines everything and the toothbrush is hilarious. A great teacher knows how to keep an audience focused. 👍

Dude! This is probably the most lucid explanation. Thanks a lot. This helped me very much.

I know nothing about cars and I am on my third differential, same vehicle. I decided to see what this part looks like and came upon this video. I thoroughly enjoyed the detail and explanation.

This is the most accurate break down of a rear dif ive ever seen. You even covered the tooth brush and brothers underwear aspect which most people forget to mention. Excellent work!

No wasted time with unnecessary dialog. Right to the point. Thanks!! Hypoid spiral bevel gears.

That was so brilliant! I am actually floored at the engineering that goes into a differential. Thanks for making this video. At least your brother should have pants and 1 sock to get around 😅

Man whoever figured this out and invented this is one smart person. I had no idea that the diff allows one side of the tires to rotate at a different rate then the other on corners! But of course otherwise it that would result in skidding out and losing traction. Very interesting! Thank you!

The first video about this I've seen that uses actual parts instead of computer graphics. Great vid!

No one can be a car mechanic without clothes contributions from the brother . Haha

i like how he uses the toothbrush as a stick to explain :"D

Excellent video. Such an ingenious yet simple gearset. I once heard someone say "an open differential applies the same amount of torque to both wheels at all times". Obviously that doesn't explain how a differential works entirely, but I think it is true and can help understand why the wheels are able to turn at different speeds while going through turns, and why (when you're stuck) the wheel with no traction spins while the other remains stationary.

Sometimes you hear people say cars are overpriced or a waste of money, but there is so much innovation and knowledge that goes into building a car that I think makes it worth it. Just thinking about a guy who came up with all of this to make it happen is mind blowing, like a super advanced puzzle.

going thru the basics and making it sound very simple ! thank you

This is one of the top videos I've ever watched for anything. Excellent. Excellent. Excellent.

Thanks. Excelent time to watch it before bed time

Master class. I love people who keep the information dense. Fantastic pace. And you clearly know the details of what you are talking about. And funny too! Love everything about this. Subscribed.

Them swirly gears are art work.

How do engineers come up with such ideas.Great piece of Engineering.First time I have understood how a differential works.

As always the best KZfaq video on the subject!

I am a middle aged Woman who is working on Car and is interested anything about Cars. I don't fixed the Car myself but I want to learn about Car and Car parts and how to fix and diagnose Car problems,so, when I talk to my Mechanic I know what I am talking about. I have a 2012 Ford Escape XLT 3.0 L V6 My Car have a rear differential axle seal leak. Your detailed description of Differential really informative for me. I understand how a differential works. I am going to ask if my Mechanic can also clean the differential cover or case for me. It gets so dirty underneath the Car. I will look forward for more videos from you. Thank you!

Very clever design from very clever people. Thanks for the engineers.

Dang, that was one of the best explanatory videos I’ve watched! Thank you!

Great illustration. Can you comment if it is critical to change the differential fluid that is often shared with the transmission fluid with different drain plugs or even separate fill plugs on older consumer cars?

Such a stark contrast how pristine the internal components are, as compared to the corroded exterior!

I love all the special tools and rags. Haha

Thank you sir. This video saved my behind on my auto test. The touch of humour really helps ease the stress too. I'll be sure to come back to this channel for help with this class : )

I feel like I'm being rushed when I'm watching this

Most excellent breakdown and explanation. Top shelf! This man really knows what he is talking about!!!

It is the channel that deserves million subscribers! Very helpful videos.

Thanks bro, you showed the REAL THING and not cartoon animation like other videos. THUMB up👍👍

Best car channel ever. More car mechanical review pls

Special press got a laugh out of that one Good one

Brilliant video. I learned a lot, Thank you, sir.

Now i have actually learnt how differential works 👍👍👍👍

Thanks for the videos, we love your knowledge !!!!

You explain things well. Although me being an electronics engg, dont know why I love this mechanical stuff. Try to use your own apparels for cleaning 😂

I really love the way you explain Sir🥰

Thank you so much for all the info it really helps me understand how they work better because of you I actually passed a couple of my state mechanic certification test you have no idea how much you helped me,god bless brotha

I like this explained, fery fast and accurate

Now, this is something to watch

I've been looking about how the differential works. Thanks to this i clearly understand about it. 👌❤️

You stole my seal puller and special press!

Lol that impact "press"

Oh man I’m going for my son’s Lego Technics right now!

Well done--you really know what you're talking about.

Honestly incredible and concise info. And very specific to me who needs to swap the diff in my exact same car!

Very detailed, knowledgeable, and demonstrated passion for the work. Great job!!

These videos keep getting better!

Million thanks for in depth explanations

Nice explanation sir thankyou so much 🙏🏼🙏🏼🙏🏼

Your brother borrow them socks from me ! I need them back when your done boss !

That special press though... Enjineer

One can always rely on that special press🤗

Human brain is beautiful one side and the other side is equally ugly. I thought I am the only one making use of my old undershirts for cleaning my car. That's the perfect way of making use of it to the core. Thank you and I subscribed.

Thanks. I'm from Ukraine and like to watch your videos))

I love his special press XD XD

"It's a limited slip differential allowing power to be distributed equally to both wheels....." Marisa Tomei in "My Cousin Vinny"! Perhaps the greatest and damn sexy description of a car's differential in the history of mankind. No offense speedkar.

That is very very clear. You are the best teacher. Thank you very much 👌

Hello brother. I haven't watched your videos in awhile have been busy. I will watch all recent videos. Love the video.

Good job

Excellent, excellent, excellent. Thanks. Semper Fi, USMC.

You really explain things well.

Brilliant videos ! 👍

The blooper was probably you brother getting even 😁

Super well explained

very well made video

Thank your brother. We owe him too many things: undies, socks, toothbrushes, ...

Love from India 🇮🇳 broo..

Very beautiful pointer😀😀😀

What a Great Video! Excelent explanation. You've got a new subscriber!

Can you show us how the power flows through the gears so we can understand how it is distributed evenly or unevenly?

I am commenting before watching video and i know it will be awesome

so bigger pinion gear mean higher gear ratio, mean high speed but low torque and vice versa. i remember converting old cj5 from petrol to diesel 3CT (turbo was ct9) toyota with diahatsu rocky gearbox and differential, i learned all this at that time.

Very impressive knowledge. Great video as always.

Awesome brother

Extremely well- explained. Also, I clicked on the link in the description for your brother's old socks and t-shirts but it said there was nothing listed. Seriously I'm interested in second hand clothes. I'm very tall, was the board washer all through grammar school and college, and wore hand-me- downs from a normal size kid because my dad was too fucking cheap or stupid to get me clothes that fit.

Well done

Great vid as usual. Keep them coming....

Excellent explanation. A big thank you !

An excellent video. I like the description of the most likely failure points (breather valve, seals, bearings, bushings) at 1:50 and 7:10. The trade-off between acceleration and top speed described at 6:25 is interesting. On a motorcycle, the rear sprocket can be replaced with a larger sprocket to increase acceleration at the expense of top speed.

Cool video. Thank you.

His brother, realizing he was suddenly out of shirts and socks, had to race to the store before it closes to get more.

Damn! Oily toothbrush! (Need to get a new toothbrush...)

Wow good job 😎

You know what's crazy? My RC car literally works the same way. It even has little miniature diffs. Shit that exploded diagram looks strait outta my RC's manual. Crazy.

Very insightful videos man

Wow thank you so much

Thanks for this great video. It helps me in practical knowledge

Hello.. Your video shows many small details that actually helps in understanding! But i want to ask that which bearing get used in this differential?

well explained thank you for the time you share with us .....

Nice video. I'd like to know more about the seals mentioned at 7:14. I want to better understand how they allow for rotational movement to pass through but seal the oil. Is it just rubbing the axle? Doesn't it wear and eventually leak?

Awesome job!

Really you and your brother is a life saver..
