Suspension Basics 01: Suspension Component Movement

[@williesweetjr8713]

You have nailed presentation as well as covered all modalities, visual, auditory, even tactile with your use of illustration along with superb use of simple language to explain complex action, reactions. I taught automotive in local high school to a less than intrested audience. Your viewers want to be here and your style will bring more. Reminds me of the Jim Handy films Chevrolet made in the 30's to teach mechanical principals of there cars. I used these in my presentation during theory. If I were teaching today, yours would be used. I know this is a long comment and thank all that read to the end. I'm totally impressed!

[@GarageFab]

I'm blown away by your comment. To be compared to Handy is huge. Jam's video on how a differential works was absolute magic. And these kind words coming from an automotive teacher is an honor. I just hope I can make you proud with future videos. Thank you.

[@williesweetjr8713]

@@GarageFab You are welcome!BTW, I subscribed after the first video that the algorithm thought I might like. This was my second! I still watch Jam Handy films but really looking forward to slow days at work so I can view all your content.

[@NV72499]

Echoing many others, you do a fabulous job of using plain language to explain what is complicated. Your step by step process oriented approach is logical and easy to follow. Even your humour, Canadian spelling, adds value. I really appreciate your approach to educating us. Thank you very much.

[@BillyP-49Chevy]

I'm just starting number one now and what I got out of it was the less forward backwards the better. So the longer the bars the better. I'm going to watch every d*** video in a row and apply this to my forty nine truck build. Your explanations are excellent thank you.

[@GarageFab]

I think your understanding is correct, Sir! Lemme throw an additional piece of info in there that hopefully won’t confuse… Longer link bars are generally better on adjustable height suspension, but perhaps more important is the relationship between the length of the link bars and the length of the driveshaft. The slip yoke in a drive shaft is there to make up for the difference in front to back movement of the link bars and the driveshaft. Worded differently, if the link bars and the drive shaft were exactly the same length, you wouldn’t need a slip yoke! I’ll be working on a video soon that I’m going to call “Third Links” that talks about the relationship between suspension components (link bars/control arms) and non-suspension components like drive shafts, tie rod ends, etc. I think that one will be pretty interesting. 👏

[@brianhamalainen8817]

You earned my subscription to your channel in a basic intro! Humble learning/teaching with explanations for 'why'? Yes, please! I 'failed' (stagnated) out of college for the same reasons you gave... Turns out that I was/am autistic, and most of us just can't learn by drilling of formulae without the 'why/how'.

[@GarageFab]

Thank you, Brian! I’m excited to have you on board. Your words mean a great deal to me and have provided me with some much needed motivation. So you in the next one!! 👊

[@jjones9290]

1:38 "Why?"- I'll add, "don't ask why, just do it!" We must have been coworkers and classmates my friend! I don't even need to finish the vid and I know I'm subscribing! I have learned that most of the time the reason I recieved answers like that throughout the years was because whoever was teaching me didn't know the why themselves! I wouldn't settle for being handed a fish, especially when I didn't know what kind it was!

[@GarageFab]

Haha! Yes!!! 🙌 I hope I can convince most of my audience to understand why “why” is so important. Not only for information retention, but also to help find teachers worth listening to. Learners should ask why childishly until the teacher can answer in basic knowledge. Glad to have you my man!

[@thebigbus1]

I'm a layman just trying to get a better understanding of suspensions. You have hit the nail on the head where most miss. A huge pet peeve of mine, when learning any new subject, is that so many people or websites or videos just jump in to the "THIS is how you DO it", instead of, "this is WHY You do it.". This seems to be rampant in society and I'm not sure why. I'm very OCD so if I don't understand WHY I'm to do something, I become a bit paralyzed with overthinking. It's hard to find this info. I've been searching high and low about suspension movement and why certain changes don't just rip bolts out of their mounting points due to axle rotation, etc. So, thank you for this. I'm looking forward to watching this little series. It's obvious you enjoy not only the "how" but the "why", and I think the foundational "why" will always (almost) lead to a better "how".

[@GarageFab]

You’re my type of person my friend. School was always the how and rarely they why. Perhaps I’m abnormal, but often the why is enough for me to come up with my own how. How’s the journey going so far? Have you got a project or just a desire to learn?

[@petem6291]

Very nice illustration /explanation of how the rear suspension has arc travel showing the push and pull . I have always wondered why on my 67 Chevy with rear trailing arms the drive shaft is a fixed length from the carrier, bearing to the rear axle I always wondered why it did not need a slip shaft somewhere in the drive shaft all I can figure is that the travel is so limited maybe 10 or 11 inches total ( in stock form )

[@GarageFab]

Thank you Pete! Without actually measuring, I would guess that the length of your driveshaft is the same as the distance between the front and rear axis of your trailing arms. I’ll soon be working on a video I plan to call “Third Links” That discuss how non-suspension components (like driveshafts, CV axles, steering tie rods, air every motorcycle chains) interact with suspension components as they move. I think it’ll be really interesting. See you then!

Thank you for the kind words, Doug! The IFS is certainly coming just as soon as we wrap up the rear on my Wife’s Mighty Max, but it could be quite some time until I get to talk about independent rear setups. My next truck build which I’m incredibly excited about unveiling will be fully independent front and rear so the discussion will definitely be had. But unfortunately not until next year if I’m being realistic. Hopefully you’ll stick around for it. It won’t disappoint.

[@arvkalsi]

Can you explain why some install the parallel 4 link on the inside of the frame rails and other install it on the outside of the frame rails? Is one better than the other ?

[@GarageFab]

I’ll answer in reverse order. Mounting link bars as close to the wheels as possible provides more axle stability. Therefore mounting link bars on the outside of the frame is generally better. Imagine, if you can, the bench press at the gym. With your hands positioned close to the weights, you’ll have far more control of the bar than you would if you put your hands closer together. Using this comparison, hopefully you can see how wider set bars can limit abnormal motions of an axle. Mounting bars closer to the wheels also put less stress on the axle tube if you’re mounting springs/bags on the link bars. So why doesn’t everybody position their link bars on the outside of the frame? The factory design of the frame has a lot to do with it. Two excellent real world examples are the 70s Chevy C10 and the Mitsubishi Mighty Max. The C10 has a fairly narrow frame with LOTS of room for bars on the outside of the frame. In fact the leaf springs are originally mounted on the outside of the frame. On the other hand, the Mightymax frame rails are built in very close proximity to the wheels. The leaf springs are mounted under the frame. There is absolutely no room for link bars on the outside. The only options are to either mount the bars inside, or cut the frame off and build it from scratch so that you can mount the bars closer to the wheels. Most commonly people choose the easier option. Let me know what you think!

[@arvkalsi]

You just pinpointed an issue i have struggled with since i was a child and i don’t think i ever realized exactly what it is. Asking and wanting to know why.

[@GarageFab]

Right?! I don’t what point we stopped asking why. Maybe after our parents said it was annoying. I think this is why I failed so miserably in school. There wasn’t much focus on the reason for things.

[@bigzoffroad]

@@GarageFab Yup!! In order to finish high school i had to redo math from pre-algebra. Thankfully i was able to find a college professor that insisted on explaining “why” for everything, and multiple methods to every problem. With his instruction i really excelled. And it’s something that I’ve started to enjoy about the welding and fabrication community is a lot of people are like minded and if you ask why, a lot of them are ready to explain. Some won’t, and i almost assume it’s because they don’t know why and they’re just doing what they were told to do.

[@GarageFab]

@@bigzoffroad Our histories are shockingly similar.

[@carmel721]

The only inaccuracy I saw was when you said that the full size link bar and the model link bar are the same. The full size link bar had revolute joints in it. That means that they only have 1° of freedom which is rotation. That’s it. The model link bar had spherical joints at each end, which means each one of them has 3° of freedom (rotation about X, Y and Z) The full-size link bar can create a planer mechanism whereas the model link bar will inevitably take your mechanism into a spatial realm. This means that your axle will eventually be able to move side to side and not just up and down.

Brother in your book you are a God in this area. You may have covered this and I apologize. But I have a 71 gmc c10 that I put 4in drop coils in the rear and 2.5 in drop spindles in the front. The root of my question lies with the fact I have a two piece drive shaft. For my calculations am I purely only using the block/tranny ,the drive shaft at the rear ended and the pinion at the rearend. Does the forward drive shaft not come into play? Thank you for your time. I’m a HUGE FAN!!

[@GarageFab]

Thank you for the kind words my friend. Certainly NOT a God in any way. Have you already seen my driveshaft video? THE Driveshaft Video. The Nature of U Joints. Suspension Basics Ep. 06 kzbin.info/www/bejne/j5ixi5l_h5JrhMk I don’t remember discussing two piece shafts in that video but the basics are still necessary to understand the advice I’m about to give… You will more or less be IGNORING your trans/crank angle. Instead, you’ll be matching your pinion angle to the first section of driveshaft. (Shaft inside the differential will be parallel to the first drive shaft at the transmission) Ideally your front shaft will be about 1° up or down in relation to your transmission angle. 1° away from a straight U joint will keep the needle bearings and grease in the joint moving, preventing premature wear. So an example of a good set up would be Engine/trans is that 3° down, first section of driveshaft is at 2° down, and your pinion angle is at 2° up.

I'm planning on installing a four link on a 60 Buick Electra. The body is currently off of the frame which I thought would make life easier to measure/install/weld. But since I don't have the body to determine my final ride height I'm wondering how I can determine that. I'm using the factory rear differential which has a panhard bar. If I remove the factory coil springs and set the diff where the panhard bar is level would that be close to factory ride height? Any help is appreciated. Great presentation! Your videos are very helpful. I wish I had a shop teacher like you in highschool.

[@GarageFab]

Thank you TJ! Body off is definitely the way to go. It creates some challenges and unfortunately math is involved but overall the build will be much easier! The Electra is a super cool car. I can’t wait to see where you go with it. What are your full plans for the suspension? Will it be adjustable height? Lowered but static? I ask because most of the time you don’t need to know factory height. You get to make it all up as you go. But yes, assuming the vehicle was built with modern principles in mind, if the panhard bar is level with the ground (parallel with the axle) that should be the factory ride height. Unless you’re building a static height vehicle and you know you want it 4 inches lower than it was, factory height shouldn’t matter. More important things to know would be how far the frame hangs below the rocker panels. (If any), and where on the frame the center of the rear wheel opening is located. (If the axle is still mounted on the frame, it’s usually a safe assumption the axle was already centered) My final ride heights on static vehicles are based solely on the height of the frame rails, taking into consideration anything hanging below them like crossmembers or transmissions. Never the body. Usually on smaller vehicles, 2-3 inches. A longer car might be a bit different if you don’t want to scrape every driveway. This was my attempt at vomiting answers at a question I didn’t fully understand. If I missed the mark lemme know. I’ll try again.

Thanks for the response Originally I was going to use 2" lowering coil springs in the stock location. The four link brackets will need to be located on the axle near their location..... so I'm thinking coilovers. 3" lowering springs up front with factory suspension components. I've never been a fan of the ride quality on bagged cars. Plus all if the components and plumbing associated. As for the frame, it hangs below the rockers 2.5". The cross members, oil pan and transmission will be above frame rail bottoms. Exhaust will be a mother to get routed all the way to the back, but that's another enjoyable dilemma for another time. Hopefully I gave you some good info?? Thanks And happy Thanksgiving to you and yours

Thank you for this mini-series on links. This is the part of air ride suspension that confuses me the most. Will you explain if and why a reverse 4 link is bad for daily driven trucks? I want to design a link system for my Mazda b2200 xtra cab that doesn't require relocation of my fuel tank if I can.

[@GarageFab]

Haha! I most certainly will but it might be a awhile until I get there. Until then I'll give you some bits and pieces. I'm strongly anti-reverse link. There are several reasons, ranging from drive shafts pulling out of the transmission to traction and braking issues. If you have some time look up "solid axle death wobble". It's a common issue with Jeeps and some other vehicles with solid front axles. If you read for a while you'll find there are many "remedies" but no one can agree on one. "Tires, shocks, alignment, suspension joints" One thing they all have in common; forward facing link bars. I've also heard of similar wobbles in reverse link mini trucks. Lastly have you ever seen semi truck skid marks? They often appear to look like dotted lines because of wheel hop. Interestingly it's only one axle on these trucks that hops consistently. One of the rear axles is connected with rearward facing link bars and one axle has forward facing bars. Guess which one hops. The fuel tank relocation is the most common reason people opt for reverse four link but it's really not as challenging as it seems. If you can weld links bar mounts you can make some tank mounts. Then extending some fuel lines and a few wires and you're done. If you insist on keeping the tank, perhaps we can come up with a three link design with watts link or panhard bar that would work for you. You got this. Thank you!

I got a static drop 01 ram 1500 that I’m about to bag in my garage and I’m literally clueless in suspensions I really never got into it when dealing with cars but I have been a car enthusiast since before I was even allowed to turn one on. Just watching a couple of your videos I’ve learn quiet a bit and feel more confident on taking on this project but I do have a couple questions is there a way I can contact you

[@GarageFab]

That’s what I like to hear, Carlos. There’s nothing you can’t do. I’d be happy to try and guide you through it the best I can. You can hit me up here, Instagram DMs @GarageFab, or email [e-mail]

I can totally relate on the point of nobody explaining the “why.” I have to understand the “why” also before i can move ahead with anything. For example: i can’t for the life of me find on the internet or from people the answer to the question “Why use a 4 link for a street truck rather than a leaf spring setup”. There are tons of vids of guys installing 4 links for off road, for lowering, and for regular street use, but nobody ever says why! It’s just assumed it’s better. Meanwhile, there is a huge contingent of guys that swear by leafs, and say 4 link is a waste of money. They can’t explain why either, just vague statements like “ride quality”. What does that really mean? I’m building a ‘72 Bronco from ground up. Clean slate. I an a very aggressive street driver. I like to drive, corner, brake, and accelerate fast. Which is better for that, 4 link or leafs? WHY? I dunno. Thanks for all you do!

[@DoubleDetailclassicspeedshop]

I may have missed it but what did you make the scaled down link bars out of

[@GarageFab]

I actually didn’t make them! I purchased them on Amazon. I believe they were for some sort of RC truck. They’re super cool. They have tiny little Heim joints built in and it comes with several different size tubes so you can change lengths.

[@DoubleDetailclassicspeedshop]

@@GarageFab thank you

[@Levi_LS]

This is fantastic ive finally found the info ive been lookin for, finally someone who also asks why instead of doing it cause someone said so, one quick question does this info transfer over to 4x4/lifted 4 link suspensions aswell?

[@GarageFab]

The basics, absolutely! I’d be lying if I told you I knew how well each setup performed off road. But it’s pretty certain you’re going to need to deal with drive shafts, pinion angles and the geometry needed to make everything work. I can tell you that triangulated 4 links are a popular choice for both trophy trucks and rock crawlers. I’ve seen parallel 4 links on mall crawlers but who the heck knows if those can actually crawl anything. Thank you for the kind words my friend! 🙏

[@kickermatice8249]

So im getting ready to redo the suspension on my 56 cadillac, these originally had leafs i was planning on using trailing arms with aft bagsbecause space constraints because of the rear seat. Do you think this is a functional setup

[@GarageFab]

It’ll work. It’s not my favorite but you can often make it work with the factory leaf spring mounts. Just make sure you install a double cardan joint on the front of the driveshaft if it’s not there already.

I'm a little late to the party, but thanks so much for this series of videos - I'm fabbing a triangulated 4 link for a V8-swapped 1979 RX7, using a T-5 trans and 8.8" Ford rear end. Made a parallel 4 link setup with Panhard bar, ran it in Lemons races the last 2 years and it worked well but wanted to try something new, so... Next race is in about a month, so we'll see. BTW, I've been using the Triaged 4 link calculator from Dan Barcroft to check the geometry - do you have another recommendation for that? Regardless, REALLY learned a lot from your suspension video series, and enjoyed the others as well. THANK YOU!!!

[@GarageFab]

Never too late! Thank you Daniel. 🙏 You said all the right words to get my happy juices flowing. (Ew) 4 link, Old car, V8, manual trans… I’m excited to see your project. I’m not familiar with the calculator you mentioned, but still I recommend you use it! My knowledge will only get you a suspension that works without binding or breaking, with proper pinion angle regardless of suspension travel. When it comes to racing and superior traction, I can only share the basics. I simply don’t have the experience needed to understand geometry at a racing level. Best of luck my friend, and stay safe.

[@kurtludwig4783]

Let’s talk traditional hot rod buggy spring, transfers. The traditional is a 1 heavy bar attached to rear axle. Hot toddlers evolved into tube bar (2) at same position of axle but 1 top & 1 bottom . The other ends were brought together to a single mounding position. I saw a car set up by a prominent “Hollywood” builder using same traditional 2 rod but 1 was mounted at the traditional point on axle inside frame rails and the top bar was mounted on TOP of axle still on axle tube very near center section. The two bars created a diagonal plane and were asteticly strengthened to each other in 3-4 spots. Both bars attaching to forward cross member near out side frame rail. I like the look, different. Would it work? And I assume panhard or watts should be used ( big v8 no flathead ) what’s your thoughts?

[@GarageFab]

It’s very difficult for me to picture a suspension design from words, Kurt. I’m a visual guy! After reading that 20 times, I’m envisioning a wishbone suspension, where the upper links form a solid triangle, and two lower links are parallel to the frame. This is a commonly used setup and is a good design for street rods. If this is actually what you’re referring to, no axle locator system is needed. (No panhard bar or watts link necessary) The solid triangle link keeps the axle centered. Mounting the point of that triangle off-center would make handling less ideal for racing but it’s probably fine for cruising. That’s a convo for another day. As for the one link setup you mentioned, I’m struggling to see that one. I’m wondering if you meant one bar on each side. A single link would have to be huge, it would have to be solidly mounted to the axle still might not be all that stable without bracing. Once braced it would resemble the old “torque tube” suspensions. If you want to shoot me some photos, find me on Instagram @GarageFab. Maybe I can better help you.

[@kurtludwig4783]

@@GarageFab yes you got it. Origin Ford used a big tapering oblong tube to locate rear axle and just like the front “wishbone”suspension joined in center of frame. Early hot riders split front and rear to allow engine swap and lower ride height

By wild chance do you know anyone that makes an 1" or 2" extended upper ball joint for the Mitsu that will allow more suspension travel? I enjoy your videos as always...

[@GarageFab]

I don’t at the moment. People I’ve used in the past don’t make them anymore. If you’re in a pinch you can partially cut the upper control arms where they flip up and bend them down straight, and plate the bottom. That’s got me by several times. If you’re not in a hurry I’ll be making a custom control arm video sometime in the next few months.
