How a CV Axle Works
ฝัง

- Here's how a CV Axle works to turn your car's wheels.
The constant velocity axle links the rotational motion of the transmission to the hub and thus turns the car's wheels. Generally, CV axles are used on the front of FWD or AWD cars on vehicles with independent suspension.
The main advantage of the CV axle is that it allows for a very high degree of articulation, while still rotating its input and output shafts at the same speed. This is ideal for the front wheels which move up and down with the suspension, and turn sideways to steer.
The inner CV joint consists of a sliding tripod housing, that allows the axle to extend or contract. Inside, a carrier with needle bearings holds 3 rollers that allow for a small degree of swing. The carrier looks like a fidget spinner.
The outer CV joint does not telescope, however it has a very large degree of articulation, which is needed near the steering axis. It consists of an inner bearing race, a carrier, and the outer race or housing. the bearings are allowed to pivot about the central axis, but cannot rotate - allowing for constant rotation to be transferred from the input to output.
Rubber boots cover each CV joint and are typically packed with grease. Interestingly, the grease types appear different for each joint. Boot failure is the major cause of worn CV axles, once dirt enters the system and causes excessive wear.
This axle was disassembled from a 2001 Toyota Corolla and opened up to see what's inside and how it works.

Bro i can repair it easily i am mater
Good job!
That's heights of recycling/reuse..👍👍👍
And the next time you get mad at your brother, just put it back in his bureau without cleaning it.
This is the most advanced amazing marketing technique I’ve ever seen
No crazy introductory music, no life story, no side story, right to the point. Thank you.
That's my style
@@speedkar99 yessir and thats why you won me as a subscriber.
@@speedkar99 ily
Hahaha👍
And don't forget the underwear
I worked at CVJ manufacturer in Korea. He knows exact name of each part. And his explanation is perfect.
Thanks for a good video.
Thanks, good to be verified
ROK #1
well then can i be employed for a reasonable wages?
I just bought a Hyundai. Thanks for the parts!
NO BULLSHIT, FAST TALK, SIMPLE WORDS, NO FILLER, QUIRKY JOKES, IN DEPTH BREAKDOWN??? this is one great video!!!
Thanks. That's my style 😏
@@speedkar99 keep up vids like this!
It's crazy cuz I went into this video not knowing a single thing about what a CV axle is or why it's even called a CV axle and I learned much more than I asked for!!!
I really appreciate the right to the point way you made this. No stupid jokes or weird music. I've always wanted to know how the cv joint worked, now I know, thank you, Sir!
That's my style. Thanks
In a world full over over detailed prolonged youtube videos, you, sir, have done what alot of others need to do.Focus on the short attention span of the viewer. You don't over detail, its short precise and straight up. An awesome video. I will be subscribing and looking to you when i need an explanation on similar topics A+
+MAX ZEE I appreciate your kind comment, short and to the point is my style! Check out my other videos for more
exactly why he got 500k views!
that sums up my experience, big thank you.
This, and your other videos are fantastic. Diving right in, tearing things apart to their most basic level, and thoroughly identifying each component as you go. Your brother should be proud that his undergarments have the honor of appearing in such high-quality demonstrations! Thank you!
Your videos are outstanding. I'm enjoying learning how things work by someone who has a good engineering knowledge. I haven't had the courage to dismantle a CV joint!
Great explanation, no buggering around. Good job
Thanks for this! It makes a lot more sense to see it live rather than pictures.
Once I heard “My Brothers Underwear” I immediately subscribed

Excellent video! To the point demonstration without wasting the end-user's time. Thanks a lot mate.
Really good presentation. Speaking fast yet very understood. Lovely. Wish all TH-cam video on how to were like this.
Very well articulated explaination. Thanks for this lesson.
Very nice demo my friend, I love getting into the parts and seeing them component by component. The best way to understand their mechanisms. Nice editing to cut to the essential parts too so we don't waste our time watching you cut things or other dull stuff that's not very instructive. Keep up the good work.

I love your sense of humor and knowledge of terminology and workings of each peice. It's very impressive!
Haha I'm glad you enjoyed it
Excellent, thank you! Must say there is an understanding of rotational motion physics in the design of the components. Pretty cool.
Thanks to your videos, I really appreciate driving my car much more since I am more aware of what is working to move it.
I sure have a different train of thought when I drive cars now too
Very ingenious design. If I was asked how they work before watching this video my explanation would have been waaaaaay off. Thanks for sharing!
I didn't know myself either until I opened up this CV
These videos really are a treasure. Great explanation and visuals while keeping it concise. Thanks for keeping these coming!
+CidH Thanks I am glad you enjoy them!
Thanks for the simple and straight forward explanation of the CV joint. Cheers!
Glad you enjoyed it
wow!!! Way you explain is really engaging, no side tracking. thanks man
Glad it was helpful!

Imteressante isso.
All your content gets right to the point with no bullshit. I also like the well-written write-ups. Great job!
Glad you appreciate it!
I really started loving your videos , no one is there to explain these things like you.Great job!! Thanks
Thanks for sharing the video. straight to the point and good explanation about the CV joint ,and how it works .
What a great concise explanation. Smart dude! I learned a lot here. Thanks man!
You are welcome
Holy smokes great video! This guy definitely knows what he's talking about.
+Tony Pedroza thanks glad it helps
Having mine replaced right now, not even that mad considering how cool the jointd turned out to be. Had one not gone bad I wouldn't have watched this awesome video. Blew my mind honestly haha thanks!
Love the info you have helped me I've got play outer CV joint thank😊
Excellent video! Cuts out the crap, explains the good details, uses brother's underwear.
Five stars. ⭐⭐⭐⭐⭐
Thanks for the kind feedback!
Very well made, informative and enjoyable. Thanks for the quality content ❤️👍😊
Your welcome
Thank you for this informative posting and getting right to the point. Blessings!
Very nice tutorial. It amazes me how man is able to solve problems that make our daily lives better but on the other hand we are adept at screwing things us that adds to human misery. I'm 73 and still enjoy listening and learning. Thanks
I'm glad you appreciate learning

Hope this monetized because this guy deserves some cash flow for this deep of an explanation/demonstration
Thanks
Great job keeping your videos unique. Old underwear makes great grease rags!
and your brother can put it back on when you're finished.
I would have used my own old underwear, I know what they been through. No telling where your brother's underwear has been...

Best story telling of cv axle. Thanx !
As so many have already commented; great with so much information and knowledge in short time! Key is that you don't leave out information, a mistake many others do. Great video!
+Leif Enblom thanks. I try to put as much info in a short amount of time. To some its overwhelming, to others its brilliant if you can follow along!
I followed the video, but I couldn't re-assemble the CV Axle.
+Charles McCarthy How far did you get...grinding it open? Lol
did you use your brother's old underwear like he did in the video?
a Dammit. I knew I had missed something.
+a haha
Gotta use the right tools for the right job
At least now his brother's ball bearings will be well lubed when he returns the underwear.
thanks for your wasting time very appreciate, this is the best video for CV Axel education
Your welcome
Best 6 minutes I ever spent on TH-cam! 👍
Absolutely perfect video.
Thanks

Great stuff!
Using your brother's stuff stil gets me every time 😂
+Hamza Raissouli thanks, wait until you see today's video...
thanks you, def the best video i personally have seen in regards to this topic.
Just wanted to say thank you for this great in-depth explanation. I've had an issue with mine on a vehicle and then got curious on how they worked and this was exactly what I was looking for.
Great to hear!
gracias
You make awesome videos.

Fanks bro! Short and sweet but packs a punch!
Excellent explaination without any side business, Loved it !!
It wasn't stuck. There's a snap ring that is recessed in the inner race and when you clean off the grease it reveals it. You need to use the snap ring pliers while tapping it off with a hammer.
When I lived in Alaska you had to "winterize" your lower 48 and put on high quality rubber CV boots that would not harden in the extreme cold.
My good man you did an excellent presentation explaining a cv joint axle.
Very interesting, and clear explanation of how these joints work. Thanks
Really wondering how much force these tiny metal parts can withstand which move such heavy wheels with all those burnouts. 🤔🙏
The small components are all in compression. They can take alot of loading, but eventually they do wear out.
Brother: "I feel....funky..."
Great video. Much higher quality narration then the driveway workshop would have me expecting. Love the work.
Thanks. Yep I try to keep my work concise and sweet
In a word, he is awesome. I mean the way he presented the fact of CV joint. Thanks bro.
I did my cv axle last week, it's cool to see how they work thanks. also is it recommended to do both at the same time or as they are needed
+LFDS94 Great. Axles don't have to be replaced in pairs.
LFDS94 I subscribed to your channel and I want to share my channel
Thank u man now I know what I have to do with my old underwears😁
Oh they are awesome for greasy situations
You explained very well. Thank you so much for sharing this wonderful information.
Yo man I just want to commend you on not only great quality content and no bs, but your diction is on point. No filler words. Correct terminology. Just professional work sprinkled with just the right amount of tasteful humor. Masterful work!
Glad you appreciate my videos
So the outter axle housing (cv side that goes to the hub) is attached to the rotating shaft by just those 6 ball bearings inside the cage? So the entire thing could come off while driving if you ignore the clicking for too long?
+mrsemifixit Yes its ts just held by the bearings. Remember that the axle in normal driving conditions only extends so far, its only if the axle is pulled straight that i t may pop out
speedkar99 I mean if the bearings or that cv housing wear out enough it couldn't separate from that shaft? I ask because mine has been clicking for a couple years lol
+mrsemifixit Yes it can separate. Then your car will be disabled, as the axle will turn without the wheel. The differential will take all power to that free spinning axle and your left going no where. Its a good idea to replace it soon.
If none of the boots are ripped, how can you determine which side is bad? I hear the clicking only when taking right turns
mrsemifixit
If you have aftermarket rims and tires on your car that are wider or bigger than stock, turning the wheel full lock can sometimes have the wheels rub up against the inner wheel well. I know this because my mustang has wider tires than stock and if I turn too hard it clicks.
Where's your brother toothbrush these days? Lol. Great video as always.
+charls seal see the last clip
+charls seal His underwear made an appearance this time
Hey I got to see it at the end.

Wow I am impressed ! Very informative and concise video ! Quick, to the point, instructional and no stupid head banging music. This type of video sells, thanks for not just dragging the demonstration out to like 20 minutes long.
+tony mememe thanks I'm glad you appreciate my video style.
I don't think this type of video sells though...
Now that was excellent, now I know my CV axle , inside and out!
2:23 *So I'm just gonna use MY BROTHER'S UNDERWEAR HERE...* OMG had me rolling, totally random comment.
Of course....best to clean up grease
He grease his brothers drawers! 😂😂
+Eric Deshields yes so does he when he leaves his undies everywhere
Idk if you know but thats off boondock saints
Great Tutorial and in under 6 minutes at that, who else can do that. You really know your stuff, I can tell by your explanation of the CV Axle components.
+Joe De Jesus Thank you
I did a bit of research before tackling this
This dissection of the CV axle is incredibly well articulated and most educational. Thanks for taking the time to make the vid. Also, thanks for the tip on re-purposing old underwear.
Ok, but where can I buy a pair of your brother's old underwear?
+MrTeknotronic you don't have a brother do you?
speedkar99 Well, I have a sister. But it seems weird to use her old underwear to clean car parts.
MrTeknotronic wed
MrTeknotronic hahaha
MrTeknotronic I subscribed to your channel and I want to share my channel
Your brother must be set to go shopping for new underwears regularly every time you make a car repair video.
This is like bullet points in video format. Great content
this is the best explanatory video ive ever seen.
Mmmm theres something about a well greased joint.
+iPervy A well greased joint is a happy joint.
Amen :)
My brother's old underwear 😂😂😂
+Vaisakh V best for greasy situations
Awesome explanation. I never knew how that worked
I’m lost for words. Your explanation for things are amazing . Great job
You are welcome

Nice explanation. Now I know! Pretty well explained everything about the cv axle in under 6 minutes. Thanks!
Excellent straight to the point 👍🏾
An excellent presentation on CV Joints. There is a lot more to them than I imagined but your video makes short work of it. Thank you.
Thanks
Agreed...alot more that goes into the engineering of this overlooked part
This was an excellent discussion, and exactly what I needed. Thank you!
Glad it was helpful!
Wow That was a Great Video, now I understand completely how it works, Thank you !!!
A really nice tutorial. thanks.
with all this amazing info on youtube i feel like more people should take ownership of their cars and try DIY repairing. just a bit of reading/watching and a little bit of doing can go a long way. the initial investment in to a tool set can be daunting but is very worth it in the long run. thanks for the great content!
Awesome, and yes you are right
Excellent informative video with no filler. Thanks
Wow, this is an excellent lesson on the subject by a wonderful and professional teacher. You are the best in explaining the constant velocity (CV) concept. I owe you some tuition. An admirer from Seattle, Washington State
wonderful channel. your knowledge and the way of teaching made you a pure teacher of MACHINES.
Bloody good explanation,quick and to the point,well done.
That's my style
Wish all videos were like this, no BS, straight to the point! Thanks my friend
That's my style. Thank you
Great vid, super educational. Thank you! 🎉
Thank you!
Love this video. Direct and to the pint. Very informative.
Thanks, that's my style!
Very thorough well done video with all kinds of big words and stuff.. Well done .. Thanks man
