Universal Joints - Part 3: History and Terminology

[@billturner1960]

Hi there!! Say, just wanted you to know how very much I've appreciated and enjoyed your hugely insightful and educational presentations. I have to tell you that given the information you provide via these vids that I've successfully managed to avert potential problems and issues with mechanics and whatnot who, on the surface, love to try and purvey their "vast" knowledge, (hard to swallow when they're in their mid-twenties), but fall short when questions are presented regarding the fine details of the application, the parts they are trying to sell and of course the technical aspects of things such as runout, yadda, yadda,, In one instance I constructively called to the attention of a mechanic the maximum allowed runout for the front axle u-joints on my truck and he promptly re-worked the installation and installed the correct thickness snap rings. He apologized for the oversight and I've had great service from that installation. NO substitute for high quality parts! I look forward to more light truck presentations from you! Greatly appreciated and please keep up the stellar work!! 😎👍

[@WeberAuto]

Thank you very much

[@pbooth001]

I am very impressed with the amount of work that you put into this. It had my attention all the way through.

[@WeberAuto]

Thank you very much!

[@MPUlberg]

I've learned more watching the 3 videos than 20 plus years of tinkering in the backyard. top notch stuff to Weber auto for his dedication.

[@namenotshown9277]

excellent video, can appreciate how much time and energy has gone into the research for it, probably alot more than we know, also nice to have an accurate historical record, we owe alot to our forebears.

[@WeberAuto]

Thank you very much!

The shadow slows down when approaching noon, not speeding up. Great series!

[@WeberAuto]

+Max oobbxxx Yes, I got that backwards. Thanks for the feedback!

Universal joints were used on Shay locomotives designed by Ephraim Shay and built by the Lima Locomotive Works. This was in the mid 1800s. Although it used an external ring and the trunions were part of the shaft. The axial play in Ford closed driveline is to deal with the fact that the torque tube has a bearing as does the transmission. The slop deals with misalignment of the pivot ball socket mechanism.

[@toyotatechMDT]

Your research is brilliant Sir. I'm in the UK, I was trained calling them Hardy Spicer and Hooke. My training came from a book by VW Hillier, you may be familiar? The rubber joint we call a doughnut joint. I always there was a man called 'Hardy Spicer' so now I know! Clarence was surely a talented man. Great series.

[@WeberAuto]

+Toyota Tech Hi, thanks for the feedback. I have not heard of VW Hiller, but it sounds you were trained correctly. I had not heard the term "doughnut joint" before, thanks. John Leslie Hardy of Hardy Spicer & Co., LTD. was granted patents in the late 1930s and 1940s. There is still a driveline company with that name, see www.hardyspicer.com In reviewing their website's "About Us" link, they seem to have left out the details of the early days before 1940 with Clarence Spicer, yet they retain his name. They also say they are Australian owned now; Interesting. Thanks again!

[@MarioDallaRiva]

Super series! Thank you for the research and interesting historical finds. The old packaging and drawings are great to see also.

[@WeberAuto]

+Mario Dalla Riva Thank you, it has been a fun project!

[@jonhexom8310]

Great video, and an excellent series, Prof. Kelly.

[@WeberAuto]

Thank you!

[@paulkirkland1535]

WeberAuto: Great job sir on the history and types of universal joints​. I've learned quite a bit so far.

[@chrisharris3371]

Excellent history and interesting to know where these came from. I’m appreciate all your videos. I’m glad Eric O mentioned your series on his Southmain auto KZbin channel. Excellent work!

[@erik_dk842]

But Eric O just uses the hammer and chisel method?

[@chekelley6861]

Who knew there was so much involved? I can't wait for your next one!

[@WeberAuto]

Thank you very much!

[@LuisHernandez-we8gp]

Every video is GOLD ! thanks for everything you do to put this out.

[@WeberAuto]

+Luis Hernandez Thank you very much!

[@johnlankford9609]

this is a revealing series.I look forward too the next video.Thanks mr.Kelly

[@WeberAuto]

+john lankford Thank you!

[@anisdada1646]

Beautifully explained! So much info in these series.

[@WeberAuto]

Thank you!

[@anands6127]

Thanks for sharing this much information.Very well explained.

[@heavenscape]

Man that was interesting!! I enjoyed the science part very much. thanks a lot Prof. Kelly!!

[@WeberAuto]

+Heavenscape Thank you!

[@3134902]

sir your videos are great thank you so much for sharing your knowledge i have watched hours and hours of your videos and the quality of the content its just great that gave me the confidence to undertake some interesting projects

[@WeberAuto]

+3134902 Thank you very much! I am glad they are helpful for you. Best wishes!

[@kristianhermann5971]

Outstanding video, thanks for sharing!

[@roderickwhitehead]

Excellent, excellent series!

[@davidvanniekerk3813]

Thank you Mr Kelly. It is most interesting. I also now understand the Hooks or dubble hooks joint.

[@RobertSzasz]

At 10:00 you seemed to be saying the time for the shadow to go from 6 to 7 is longer than it takes to go from 11 to noon. If you look at it again for a moment, the time marking is spaced further apart in the morning and evening. This shows the shadow is moving slowest around noon. (smallest distance per unit time) Keep up the great videos!

[@WeberAuto]

You are correct, I had that backwards! Thanks for the feedback!

[@jimbuford4147]

Very informative and just plain fascinating.

[@WeberAuto]

+Jim Buford Thank you!

[@Stelios.Posantzis]

Fascinating stuff, as always!

[@ts3787]

Thank you professor for your time and enthusiasm tackling these subjects seem everybody overlook nowadays. Specially certain car magazine channels... I remember it took you more than 1 hr to set a differential PRO-PER-LY while our gung-ho youtuber mechanic fella took 10 min to smack together the parts and ensure us all-is-fine now. Maybe we should recommend them watch and learn from your channel instead of misguiding public in such a gross manner. Anyhow, thank you very much, please keep posting.

[@WeberAuto]

+ts3787 Hi, thank you very much! I know what you mean, some of those videos absolutely scare me. I am sure some of those people think they are doing the very best job that can be done; they just don't know any better. "They don't know what they don't know". People have to want to learn before they will be open to the fact that they might be doing it wrong. That is a difficult thing to admit. I was the same way when I was younger. Thanks for your feedback!

[@tjm3900]

In the UK I knew the Rubber 'Hardy Spicer' Doughnut as a Rotoflex doughnut. Hardy Spicer joints (to me) were the typical Dana Spicer joints that you mainly talk about. Rotoflex joints were used on many cars before CV joints be came popular/reliable/inexpensive. Used by Lotus, Hillman and Triumph on drive axels in conjunction with a metal Spicer joint for independent rear suspension.

[@geojor]

thanks for your efforts in these informative videos...

[@WeberAuto]

+pei bossman Thank you!

[@stephenbianchi7141]

I thought, "15 mins should be enough time for simple ol u joints". Boy was i wrong... I amaze friends with my automotive knowledge after watching your videos.

[@WeberAuto]

+Stephen Bianchi That is awesome! There is a lot more to come. Thanks for watching!

[@2Phast4Rocket]

Another great video plus a historical background of the universal joint. Also, Robert Hooke is also known for the Hooke's law (F = Kx) where the K is the spring constant. This law is known by all physics and engineering students

[@WeberAuto]

Thank you. From what I have read, Robert Hooke was an amazing man.

[@originalCN4]

Very interesting info about the spicer products

[@websitesthatneedanem]

Very, very interesting!

[@shawn01754]

Excellent video! If I remember correctly replacing the factory u joints on my 1969 GTO, there were no retainer clips. GM injected some sort of plastic. And to disassemble, you had to carefully heat the area until it popped. Then... the plastic came out like a snake. I was amazed

[@WeberAuto]

+Shawn Kelly Hi Shawn. I was taught to heat those up to, but it turns out that is a mistake. A press should be used to just shear the plastic retainers. If you use heat and then do not clean out all the residual plastic from the yoke ears, the driveshaft will be out of balance when you are done. Thanks for your feedback!

[@TheAustinCarmichael2]

Wow, I just stumbled on to this video, and I'll definitely be back, great content

[@WeberAuto]

+TheAustinCarmichael2 Thank you!

[@marksteven3534]

The standard by which the history of universal joints will be measured is presented right here.

[@WeberAuto]

Thank you very much!

[@alvinnagra9695]

great video very interesting waiting for more

[@WeberAuto]

+Alvin Nagra Thank you!

[@mvargass]

awesome info, thanks for this videos.

[@WeberAuto]

+marcos vargas Thank you for watching!

[@av8bvma513]

Excellent series of well researched lessons, many thanks. Point of order, 10min in, I am splitting hairs, but the angular displacement and the speed of the shadow are reversed to your description, faster in the morn/evening, and slower towards noon. The time is the same for each index, as they are hour markers, but the distance travelled and the speed vary.

[@WeberAuto]

Thanks for your feedback. You are absolutely right, I had that backwards! Thanks for watching!

[@tt-rs1457]

Awesome Video. Here in germany, we called this rubber coupling joint also "Hardyscheibe" as you told.....:-)

[@WeberAuto]

Thanks for your feedback. Now you know that Hardy name should not even be associated with the universal joint.

[@ranahamayun9919]

You doing very good job 👍👍👍👍👍

[@kuichen1649]

Thank you ☻

[@WeberAuto]

+KUI CHEN Thanks for watching!

[@hobbang7097]

great great thanks

[@offroader22]

Interesting note about the Swedes. Talking to Swedes about universal joint (And as I race offroad trucks in Sweden that subject comes up A LOT) they use the name Kardan/Cardan more consequent than any. And often also referring to the whole drive shaft as a cardan/kardan. In Norway however, very annoyingly, a cardanaxle is somethimes used when referring to a drive shaft while just cardan is used when referring to the differential. This is obviously quite wrong, but very well indoctrinated into the technical language of most mechanics and others.

[@WeberAuto]

That is great feedback; very interesting. Thank you!

[@ProjectXJ]

So should you not grease the caps before installing them? I know it's standard practice to put grease in the cap to keep the needle bearings in place while installing.

[@WeberAuto]

It depends on the joint and how you install it. The rest of the series explains all of that

[@ProjectXJ]

@@WeberAuto still in the middle of part 4 right now. It never seemed like they put enough grease in the cup. But it seems like if i put too much, it will get squeezed out when putting the cup on.

[@joshoetjes122]

Thank you John, that was very interesting. Specially the "play"on the ford u-joint :-) It's like what I have on my Land Rover from 1971 :-( Know I know what to do, watching the other video's. My land Rover and I say; Thank you, Greetings from the Netherlands Europe. I'm "Hooke-d"to your channel now :-)

[@WeberAuto]

Thank you very much!

[@thesetruths1404]

Do you know anyone who has compared wear, load abilities, and resistance to operational grime with OEM new u-joints and a few popular aftermarket brands too?

[@peterneilson9435]

Just curious what your thoughts are on rebuilding a double Hookes joint? Is it practical to do?

[@WeberAuto]

It depends upon the availability and cost of the parts. Many Spicer parts are available. See their Small Parts Catalog online.

[@Kiro-up2qg]

i have a request sir can you explain how semi floating axle and full floating axle works?

[@DrJunge]

The link to the cited paper by Alan Mills: rsnr.royalsocietypublishing.org/content/61/2/219.full.pdf+html

[@WeberAuto]

+Mirko Junge Yes, that is the one! Thank you!

[@paulandresbernal271]

excellent knowledge delivery, but it is very difficult to understand for me, you could put your very grateful subtitulo serious classes

[@WeberAuto]

+Paul Andres Bernal I will work on subtitles

[@stone-hand]

Chrystopher Pelham, the Swedish answer to Comrade Popoff..

[@Stelios.Posantzis]

Now I know who buys this stuff on ebay! Fascinating though the history of U joints may be, now the question of why on earth somebody would make a cardboard box with metal edges at the joints keeps niggling me at the back of my mind .... I mean really.. why??

[@Stelios.Posantzis]

Never mind answering that: I guess it was probably done so that the boxes would withstand the weight if 50 of them were stacked on top of each other. Seemed like a bigger puzzle at first.

[@pjames4413]

don't take any shortcuts.
