How a Differential Works

- Here's how a differential works on a car!
The differential allows for a difference of rotation between two wheels on the same axle. This will allow a vehicle to turn corners without binding the axle or scrubbing tires.
On front wheel drive vehicles, the differential is often integrated into the transmission assembly. On rear wheel drive vehicles, power is sent through a rotating drive shaft to the rear differential assembly, before being sent out to the wheels through the CV Axle.
The differential consists of a large ring gear (or drive gear) a small pinion gear and small planet gears (spider gears) in the differential housing. When both wheels are moving at the same speed and direction (i.e. vehicle moving straight ahead) the pinion gear rotates the ring gear, which rotates the differential housing and thus each CV axle. When there's a difference in wheel speed, the spider gears start to mesh with each other, allowing one wheel to turn at a different speed than the other.
In this video, an open differential from a 2004 G35 is completely taken apart and analyzed. Other types of differentials include the locking differential and limited slip differential, which aid the disadvantages of the open differential by locking or limiting wheel slip on slippery surfaces.

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 👍🏻
“Special Press” love it!
Excellent concise breakdown! Truly a mechanical marvel! The level of undeviating engineering precision is unreal! And we all take it for granted every day!
Right. Thanks for pointing it out. Literally overlooked that
@@tonychavez4056- Sarcasm? Or did you reply to the wrong comment? Or ?
Thanks. We sure do take it for granted until you get stuck on a patch of ice and wished you had the LSD or a locker
@@foadrightnow5725 I was literally at the end of the video and decided to up vote the comments. Reading yours made me realize I didn't really look at it with amazement. Just meh. So I make a point in thanking you for reminding me. I do take this for granted. Appreciate the reply looking for understanding. Was so tired, I didn't want to explain myself last night so just gave you a thumbs up.
@@tonychavez4056 - No worries, friend. Cheers!
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.
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!
Haha thanks
Excellent explanation. A big thank you !
Thanks for the videos, we love your knowledge !!!!
going thru the basics and making it sound very simple ! thank you
You are welcome
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 have watched dozens of RUclips 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.
Dude! This is probably the most lucid explanation. Thanks a lot. This helped me very much.
Thanks for this great video. It helps me in practical knowledge
That is very very clear. You are the best teacher. Thank you very much 👌
well explained thank you for the time you share with us .....
Amazingly explained!!
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.
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.
Brilliant video. I learned a lot, Thank you, sir.
Excellent video brother. Thanks.
As always the best RUclips video on the subject!
Thanks very much for your compliment
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.
Very detailed, knowledgeable, and demonstrated passion for the work. Great job!!
Honestly incredible and concise info. And very specific to me who needs to swap the diff in my exact same car!
You really explain things well.
Million thanks for in depth explanations
You are welcome
Really you and your brother is a life saver..
Dang, that was one of the best explanatory videos I’ve watched! Thank you!
Cool video. Thank you.
Very informative and interesting - thank you Sir.
I like this explained, fery fast and accurate
Super well explained
I really love the way you explain Sir🥰
Great explanation!! 👍👍👍
Most excellent breakdown and explanation. Top shelf! This man really knows what he is talking about!!!
Very impressive knowledge.
Great video as always.
Thanks
man, i love your videos! thank u!!
Glad you enjoyed
Best car channel ever. More car mechanical review pls
No wasted time with unnecessary dialog. Right to the point. Thanks!!
Hypoid spiral bevel gears.
Thanks , that's my style
God bless you with more knowledge
🌹
Thinks for sharing
You are welcome
Nice explanation sir thankyou so much 🙏🏼🙏🏼🙏🏼
Welcome
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!
buenisimo directo al punto, yo no hablo ingles y te entendi todo
Well explained. Wow.
Nice video... Much regards from 🇱🇰Sri Lanka.. 🇱🇰
Very beautiful pointer😀😀😀
Excellent Video!
What a Great Video! Excelent explanation. You've got a new subscriber!
Special press got a laugh out of that one
Good one
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 : )
Glad it helped
Brilliant videos ! 👍
you make learning fun !
These videos keep getting better!
Thanks. Improvement is always welcome
Cool explaining bro 👌
Nice review
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.
Very insightful videos man
Thanks
I love the way he explaines everything and the toothbrush is hilarious. A great teacher knows how to keep an audience focused. 👍
Really awesome video. Great job!
Thank you
Awesome job!
Thanks
I've been looking about how the differential works. Thanks to this i clearly understand about it. 👌❤️
Glad you understand it now
Higyje el kérem , sokkal egyszerübben ( kevesebb szöveggel ) értelmesebben el lehet mondani !! . Tehát : Azt tudni kell hogy a differenciál mü kupkereke a támyérkerekkel van kapcsolatban s egyik FÉLTENGELY sincs közvetlen hajtásban . Hanem a Bolygókerekek mint egy "" ék "" adják át a nyomatékot a rózsa v napkerekeknek , melyekbe a féltengelyek bordázott része kapcsolódik . Egyenes uton való haladáskor a bolygókerekek ( kettő vagy 4 db van ) csak az ÉK szerepét töltik be az az NINCS a tengely körüli forgás. Kanyarodáskor azonban elfordulnak saját tengelyük körül kiegyenlitve a különbséget .
No one can be a car mechanic without clothes contributions from the brother . Haha
Just brilliant
Well done--you really know what you're talking about.
Thanks glad you like it
Well done
This is great, thanks a ton! One question, do you have to pull the 3rd from the vehicle to remove the rear carrier assembly? I'm needing to swap mine on my 93 geo tracker and it seems to me that you necessarily wouldn't if you remove the cover of the housing?
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?
How do engineers come up with such ideas.Great piece of Engineering.First time I have understood how a differential works.
The first video about this I've seen that uses actual parts instead of computer graphics. Great vid!
Right
Oh my goodness you are right this the only practical video
i like how he uses the toothbrush as a stick to explain :"D
That's my teach-brush
@@speedkar99
Frankly speaking, I was searching for someone who explains car parts in a funny and simplified way and I finally found your channel .
So Thank you very much. 😁
Amazing !!!
cool video very informative
Nice information
Very good bro..
good video man
Now i have actually learnt how differential works 👍👍👍👍
Glad it helped
Great vid as usual. Keep them coming....
What more would you like to see?
@@speedkar99 The ones I'd like to see are the hard ones to do. Comparing generational differences between vehicles. And not even current stuff. Like compare the difference between a Toyota Tundra gen1 to gen2 or gen3 etc.. I guess it helps if you acquire old pieces of junk that don't run and want to tear them apart to talk about it, but not so easily done otherwise I bet... Learning how the suspension changed or other changes for a DIY guy is very useful.
Them swirly gears are art work.
They sure are beautiful and will make an awesome desk ornament
I love all the special tools and rags. Haha
very well made video
This is one of the top videos I've ever watched for anything. Excellent. Excellent. Excellent.
Excellent
Thanks bro, you showed the REAL THING and not cartoon animation like other videos. THUMB up👍👍
Thanks. Excelent time to watch it before bed time
This was supposed to post at 12pm not am
Awesome brother
Thanks bro
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'm glad my videos can help!
I’m going to college learning this stuff. Students use 3rd party content like this, by guys like karspeed making real effort to make good content, and professors get to keep their low effort half arsed jobs using old crappy power points. Sad but true lol
I never going to let you use my TOOTH BRUSH again , LOL
You don't have to let me use it. It'll go missing one day
im thinking of making a steel bender for my wrought iron work will a dif like the one in the video provide enough torque to bend steel?
Thanks !
Great video. I only have one question about the spring in the LSD. What exactly causes it to compress to allow the clutch packs to seperate? I understand that the difference in wheel speed initiates it, but what actually compresses the spring mechanically?
Wow thank you so much
You are welcome
Now, this is something to watch
Sweet!
I love his special press XD XD
It is the channel that deserves million subscribers! Very helpful videos.
I wish I could get a million one day! Help by sharing my videos
Are the pinion bearings a weak spot (common failure point) on these? If so, could you kindly explain why?
Hey, I just bought a 2016 Ford Tauras SHO.
I want to rebuild the PTU using a cast iron housing and better alloy gears.
I also want to add a cooling system that uses the same gear oil in it as the differential.
Can I use the same gear oil in both?
Nice
Good job
Thanks
Lol that impact "press"
Hammer time!
I hope you still look at and comment on these older videos. I have been planning to build a tracked vehicle and like most of the one's I see they use an open differential and brake one side or the other to turn but the limitations talked about are the lack of traction. If I were to take 2 differentials and cut the right side off of one and the left side off the other and welded the shaft so that the cut side would never move and mounted them side by side would they get full torque while braking the one side ? I hope this is a little more clear than mud.
Very clever design from very clever people.
Thanks for the engineers.
You are welcome
