THE Driveshaft Video. The Nature of U Joints. Suspension Basics Ep. 06

Did you know driveshaft speeds sometimes change as they rotate? This speed change becomes more extreme as the angle of the U joints increase. This video uses a machine to demonstrate how U joints cause crazy vibrations if not setup properly. We discuss the importance of proper pinion angle to prevent drive shaft speed oscillations (vibrations) and how to correct them.

  • 40 years working on cars from dealerships to speed shops and that simple demonstration explained everything. 👌
  • @OutdoorAuto
    I just have to say I really appreciate the level of work you put into this video.... cant even imagine the hours you put into this
  • I've never responded to any YouTube video but the actual driveshaft sprocket sound is undisputable. Perfect explanation.
  • @aldenc8453
    Bro the matrix intro/outro looked so good I legit thought it was a clip from one of the films at first …and then when the handsome fella in the yellow shirt came on screen and asked that question and you just straight up laughed in your face I LOST it lmao 💀💀 …and then you cut that double cardan section of that drive shaft in half just to get that 2 second shot just to help us understand better….I’m just tryin to say that I see you bro. And all of the effort that it must take to put together content like this that explains relatively difficult topics effectively and simply and is genuinely entertaining and funny at the same time. I watched a bunch of pinion angle videos and read through so many forum threads and not a single one thought to mention the importance of ensuring that the u-joints are “in-phase”. It might be something so obvious and simple that nobody else imagined that someone could mess that up… but yeah I really appreciate you helping me to fix my 96 bronco’s driveline. I’ve never been so stoked to subscribe to a YouTube channel. Thanks again, man!

    YESSSS! Just yesterday I checked your channel to see if I had been, once again, unsubbed from one of my favorite channels (I frickin HATE that about YT). Been missing your content. As soon as I just saw the alert, I dumped the current video I was watching and came here - lol. As I've said before, you my friend, have a gift for teaching. The props and the humor make learning fun and interesting for this old boy. Never a dull moment when watching your stuff. If the teachers at our public schools had half of your teaching skills, this country would be so much higher in the world rankings. Seriously. You have a gift young man. Thank you for sharing it with us mortals - lol.
  • @drtreebo9037
    Just watched the basic suspension videos and I gotta say. 1. I love the way you verbally explain things. Its both educational and humorous. 2. I mega appreciate the fact you take time to make visual explanations and that they're not all just animated. You take real time and effort into explaining it so people watching and listening can learn. You are nailing what you're trying to do so dont stop. Keep it up! You guys have the right energy!
  • @norcoridermtb
    I know this is old content, but I’m designing a parallel 4 link rear airbag suspension for my f350, and this was BY FAR, the most helpful, simple to understand, playlist of info I could find anywhere. From setting pinion angle, to simplifying the rectangle shape I need for the links, bushing type, perfection. Thank you for putting this together it should be in mechanical classrooms everywhere!
  • @4btguy945
    Dude I am a small truck guy, on the drag race side. I have learned more from you about suspension in an hour than years of reading books and trying to piece information together. Thank you!
  • 5 minutes in, and this is already the best video on this subject I’ve seen yet, and the rest of your content is excellent also. Keep up the good work.👍👌
  • @Waikatotek
    Our boy has just started studying for automotive. Going to show him these when he’s ready. Easily explained! I even tested a guy on DS joint phasing the other week and he was stumped. I’m still learning watching these.
  • @bornwestusa
    One of the best YouTube productions I have ever seen. Great job with everything.
  • @jaybauer6978
    So glad you’re back! Best, most positive and encouraging fabrication channel out there. Can’t wait for your next episode!
  • Your content also helps motivate some of us to get back on the projects sitting around unfinished.

    Some YouTubers post every day....... To me, that's nuts. Yes, YouTubers can generate a lot of money. Their channel turned from fun to a full time job... which may take the fun out because of the pressure to produce. Best to find an equilibrium. Produce when it feels right. If daily or weekly, monthly or randomly works, then do what works. This Old Tony took a long break for personal reasons. He's not back as often, but I think his followers, like yours, simply find a new video like an unexpected present. This is the first time I've seen your channel. I'm very impressed. You've got something. Excellent information. Excellent demonstration and just the right amount of well done humor. I done learned a lot. Great video 👍
  • @DaveNorthWest
    Of all the pinion angle videos I've watched this is the only one that makes since without a bunch of weird stuff that isn't necessary to be talking about or the author treating the audience like there a bunch of 7yr old's. Thanks for this!
  • @draglinemazda
    You've been gone so long I've moved on, but it's not you it's me......I just need something more stable 🤣. Glad to see you're back man.
  • @ronbelldvm
    Whoa!!! My mind just got blown! That was a great explanation of pinion angle and U-joints, and how they interact to cause/eliminate vibration. I really liked your training aid. It really showed how the link bars keep pinion angle set. I know in your first episode you wanted to share what you have learned over the years, and I will tell you, you are really good at teaching this stuff. Thanks so much for taking the time to make these videos. Keep up the good work.
  • @FlatFifties
    This episode is priceless. I don't work on or modify cars, but I just bought a tractor with PTO shaft driven implements. The information you have given me is invaluable to eliminate vibrations in my PTO driven implements.
  • @vanblindguy4600
    Your props and video editing make all the difference in the world and is the obvious difference between your "new" channel and every other startup channel on You Tube. Things as simple as the playing with the aperture during still shots. mics, and transitions are near production levels. So if your doing it yourself.. Wow. If your paying someone to do it, it is money WELL spent. Obviously your personality, speech cadence and continuity are either natural or well trained. KUDOS to you.
