[@nickcautrell2514]

It's nice to see a thorough video that doesn't just repeat the same stuff that everybody else has. It's also nice watching a video where they'll talk about something in my mind I'll be thinking yeah but what about this part or that part of it and then about that time you actually go through and explain it. The chromoly versus mild steel for the link bars was a perfect example. Everybody's like you need chromoly. One bands one breaks if it isn't welded properly. Just like you said, a Bent link bar will get you farther than a broken one. I agree for the most part on your breakdown between the poly and the rubber bushings. Race vehicles generally you're going to want himes or big poly bushings. If it's something that requires a lot of movement or articulation the rubber bushings yes as you stated, won't last as long. If it's something you're going to be driving a lot on a street vehicle and like on yours where there's long link bars and not 2 ft of wheel travel I would have ran rubber bushings. A good quality rubber bushing will last for years without any lube, dirt collecting around the lube, or squeaking because he didn't lube them. Also poly bushings when they get loose they clunk just like a tie rod. Each type has a place, it just depends on what you're doing with it. Still like your content though.

[@designandbuild3953]

I just discovered your channel 20 minutes ago, love it and subscribed instantly with notification! I'm not smart, but I am a mechanical engineer. I pursued that education specifically so I could build things with steel. I too struggled with how to articulate why one would use chromoly over mild steel with my hot rod buddies, particularly with the cost differences, and where is the dividing line to make that decision. What you said was a spot on explanation, best I've heard to date, and got the point across perfectly well. One would choose chromoly over steel for one of two reasons; 1. Money is no object and weight savings is absolutely key to your goals, i.e. sponsored race team like you said, or 2. you need a lot of strength in a part but have a limited amount of space to put it in. Chromoly is the most accessible option of the high dollar steels. i.e. home made axle stub shafts. Proper annealing is the difference between success and failure as you described, most home growers get cracks at the weld zone until they crack the heat treat code. Awesome channel, I'm looking forward to binge watching your content over the next few months in the boring evenings on my out of town assignment.

[@GarageFab]

You sound pretty dang smart to me. I’ve pondered for a long time about going to school for engineering! The funny thing is I have no desire to get a degree, I just want to better myself and my projects by learning more than I could on my own. Thank you my friend! You are appreciated. We’ll be seeing you around! 🍻

[@GarageFab]

My pleasure my man. “Why” is always the most question. Don’t accept any info unless the person can tell you why.

[@rafatrill]

Chromoly is stronger and better because of two reasons its strength and Ductivity meaning the amount of pressure it can absorb and the amount it can bend without breaking. The problem is people try to make it to stiff by welding it with stainless steel wire this makes it way to stiff causing cracks overtime. Heat treatment also does the same effect also cold treatment different topic depending on the material. U can actually weld chromoly with flux core a lot of people don't know this. There are special wires specifically for different materials. I have a college degree in welding. I don't know everything but I've learned a lot and continue to learn.

[@GarageFab]

No argument at all that chromoly is better when done properly. I plan to take some classes myself sometime soon so I find it for sure what “properly” really means. There is no better way to be… always learning.

[@GarageFab]

Haha! Thank you Brother. Eventually I’ll get around to showing off all the attachments.

[@rileyfriedman6596]

even on race cars, everything chromoly, including the chassis, is replaced at intervals. Like you said, failures are catastrophic, and the stress on the material over time will weaken it. That said, chromoly has some useful flex properties for certain applications. It's a bit "springy" compared to mild. For a vehicle that won't be competing on a track, chromoly is not an ideal option, but it certainly has its place.

[@GarageFab]

Interesting! That’s the first time I heard the tubing change. You’ve basically sealed the deal on my using DOM on the next project for much of the chassis. Heavy but that shouldn’t be a problem. Thank you, Riley!

@Garage Fab I'm getting so many ideas and proper knowledge of how suspension stuff works! I recently just had my drive shaft drop out of my 97 Dakota. While I had it out: 1. Removed all of the rust 2. I painted it 3. Replaced all the u-joints 4. Pinion yoke at the front of the differential 5. Carrier bearing that barely had and rubber attached still 6. Tranny filter/fluid 7. New gasket & pan with drain plug 8. Oil changed while I was under there 9. Differntial fluid changed (since it poured itself out while shaft was disconnected) 10. Differential cover cleaned de-rusted and painted 11. New gasket So then I lowered it down so I could top off the fluids after it was all together and noticed my rear tire was almost punching the inside of the fender.... Found out two of my four link rods were busted at the ends and one of the front hangers cracked below the weld. I decided to remove the bed: 1. Deleted the e-brake and removed the bracket that was partially torn from the frame 2. Dropped the fuel tank 3. The straps almost completely cracked apart from rust 4. Disconnected the fuel filler hose from the inlet housing (it was so rusty I'm surprised it's not leaking already. Ordered new tank straps and filler, rust remover wash and metal etch/conditioner. Rust Bullet Chassis paint. Company is sending me all new stuff! The company wants me to remove all of the old kit and return it to them. So I've been watching your videos on different ways I could set up the four link when I reinstall it, maybe install inside side of the frame instead of the outside and possibly move the fuel tank from the side of the truck to under the rear of the bed I'm not sure if that's a great idea because of possibly getting rear-ended but I don't know. My only major concerns are pinion angle of the shaft and figuring out my ride height that I want and having the bags having at least 30 pounds between them. When the kit was originally installed one of the cheapest Chinese airbags was popped so I had to buy a couple of Air lift quality bags locally which then since they were taller they required more air so my ride height was more raked. So I need to move the upper bag mounts up or the lower back mounts down when they go back in. I ordered a digital magnetic pinion angle finder help but I don't know the best way to figure out where on the axle to mount the bag mount brackets. And as long as I maintain the opinion angle I can move the front and rear hangers for the four link up as long as they still end up lined up with my infinite Center at the front of my bumper if I understand correctly. Sorry for the superlong post but you got the knowledge that I'm looking for!

I know this is a old video, but hopefully you'll still notice this question... You state that adjustable link bars must contain atleast 1 heim... Why would Thorbros sell most all of their 4-link kits with 1 adjustable end but no heims if this is the case? Will the thorbros bar ends come loose then?? Or maybe the bars are meant to be welded solid once adjusted to exact proper length?? My truck will be on road use only, so articulation will be minimal.

[@J-RocksCustoms]

Shouldn't you use a heim or jonny joint on one end of each bar to accommodate for body role? Seems like poly on both ends would wear out quick from body roll.

[@GarageFab]

I’m hearing a lot lately about failing or wearing out polyurethane bushings! I have yet to have to replace a poly bushing. On my builds, if the owner wants side to side action, or adjustable links, at least one end of each link must be a heim joint with high misalignment spacers. In vehicles with static suspension or bagged vehicles with just front and back motion, I only use polyurethane bushings. That’s not to say that’s the “right” way of doing things but it’s served me well so far.

What's up mankandy, happy New Year. While triangulated bars aren't the same length should they remain parallel to each other. Thanks, I really enjoy the depth if your videos.

[@GarageFab]

Hey Terry! I’m assuming that you’re referring to the relationship between the triangulated upper bars and the parallel lower bars. (Because if the triangulated bars were parallel they wouldn’t be triangulated) 🤔 🤯 It is my opinion that on bagged vehicles the upper and lower bars should in fact be parallel to maintain a constant pinion angle. On a static height vehicle, (metal springs, coil overs, etc.) They should not be parallel. Instead they would point to a common spot at the front of the vehicle. (Front wheels/front bumper) This will increase traction, but will give a changing pinion angle which could cause problems on an adjustable height vehicle. Thank you, Terry! Happy new year.

Are you referring to the bushings on the differential? The axle is from a Mustang that uses a triangulated 4 link design. I’m trying to get away from that design so the angled bushings wouldn’t work properly with forward-facing links. The mounts will be removed to make room for an axle support truss.

Towards the end, you show the bars beside each other, with the bushing pipes lined up like they weren't cut… What if you did them that way, and cut them after welding the bars in? Also, the l&r upper bars stay the same distance apart through movement, when they move the same. When they don't (like roll) they are always moving apart. What if you hooked them together with something that resists expansion, like the springs that pull a porch door closed (but bigger), or a shitload of bungee cords… Ghetto substitute for an anti-roll bar, that works with 'bags, as long as there is clearance under the bed! (steering dampener? Nah, that would make bumps harder & rolling slow to return)

[@GarageFab]

Thought #1: That would be interesting. You could definitely cut the bar ends later, but the sides of the bar end should be square so they don’t tear up the bushing as they rotate and I don’t think you would be able to get that assembly into a chopsaw. 🤔 Thought #2: You’re anti-roll system seems like it would work in theory. But I wouldn’t want to try to explain it at a car show. 😂

[@Iowa599]

@@GarageFab a sawzall or angle grinder would be through it quick, but after I posted that I started thinking that the first cut could end in a "ping!" Then all effort would be wasted. test the idea, then we'll work on a more fashionable way ;)

For an off-road application when finding your link mount locations on the frame, do you go off instant center? Also how do you calculate your upper link length when doing a triangulated 4 link?

[@GarageFab]

I don’t build a lot off road vehicles. That’s my way of saying I’ve never built one. 🧐 I specialize in Mini trucks that require a whole different set of rules. If I’m building a truck that’s meant to perform well at the track, center of gravity would be a deciding factor and then creating a good instant center with link angles would follow. Unfortunately with adjustable suspensions like those that I build most, instant center takes a back seat to drivability. (meaning vibration and driveline longevity) In adjustable suspension vehicles in which the driver wants to be able to drive at all heights and doesn’t care as much about quarter-mile times, I create the longest link bars the vehicle will allow. The link bars then essentially decide where to mount them to the frame. Sorry I couldn’t be more help there. As for triangulated bar length, my method is ridiculous. I did terrible in math and I’m sure there’s an easier way to calculate it on paper but here it is… On bagged vehicles the distance between the axis’ on the lower bars should match the axis’ on the triangulated upper bars for the sake of happy u joints. So I take the measurement of the straight lower bars, let’s say they’re 3 feet even. I draw two parallel lines on the ground 3 feet apart and the width of the vehicle frame. Those lines are the front and rear axis’ of the lower bars. Now you can place your unwelded bar ends on those lines where you want to mount them (perhaps the front link bar mounts are an inch away from the inside of the frame rails and the rear mounts are a couple inches apart above the differential.) You can then just measure the distance between the front and rear bushings to decide what length to cut the link bar tube to. I’m suddenly realizing while writing that I should do a video on this even though I’m not doing a triangulated 4 link. I hope this made sense in writing. 🍻

[@Central_Cali_bourbon_Barrel]

@@GarageFab my apologies, I could have worded my question better. I should have asked if your formula could be applied to an off-road application. As for the links I found a 4 link calculator on a forum last night. If you would like me to send it you way so you can check it out to let me know I can email it to. Helps with links, shocks, drive shafts and pitches needed.

[@GarageFab]

I’d love to see it. You can hit my up on Instagram @GarageFab. Feel free to shoot me a DM. The setup I recommend for Mini Trucks would in fact “work” off-road, but you’d likely be leaving some performance on the table. Maybe it would be noticeable, maybe it would not, but traction under acceleration with a parallel 4 link might not be as good as it could be with just some simple adjustments in bar angle. Simply put, if you just want to drive some trails occasionally, a parallel 4 link will serve you just fine. If you want to race, ignore everything I have to say. (Except “Keep moving forward”)

[@Go69]

I understand that you are indicating to keep the bars parallel to maintain pinion angle. However, I thought that the pinion angle being 3-5 degrees down was so that under acceleration, and a little bit of axle wrap-up, the angle would essentially zero out, or be closer to 0 than when static and not under a load. If you are running solid bars that allow NO wrap-up under acceleration, do you still need to run the pinion angle at 3-5 degrees down? I'm watching for your driveshaft video so that I can better understand how to set, and adjust, pinion angle. For example-and not to make this message too long-I have an 08 Chevy extended cab truck with the SUPER LONG aluminum driveshaft. I've blown the shaft up TWICE now because they are not meant for high speed excursions. Literally they get damaged from 130+ mph events and then induce a vibration. This last time I went to a steel driveshaft but due to it's LONG length, it too is having problems. I was told to move to a 2 piece driveshaft and all this crap would be behind me. The factory aluminum shaft was 86.5" center of U- joint cap to center of joint cap. So, now I'm moving to a 2 piece shaft for which I will have to make a cross member for the carrier bearing. To make matters worse-the truck is lowered! So... I need some help figuring out drive line angles for a 2 piece shaft on a truck that did not come that way from the factory, and one that has been lowered 6" in the rear... yep.. lots of fun.

[@GarageFab]

Haha! That does sound like fun indeed! I am working on that video literally as I type. I was questioning whether or not to include the Double Cardan joint in the video but it sounds like you could potentially benefit from it. I hope to have it out in the next couple weeks but a lot of poo is hitting fans left and right around here but I’m certainly trying. To answer your question; Yes, the 3-5 degrees down rule was created when the majority of vehicles were built with leaf springs that could wind up under load causing pinion angle to change away from the desired angle. This was/is most important with drag race vehicles. The goal then was proper U joint angles most of the time. So for your second question, If you have a link bar setup with heim joints installed, you will have zero change of the pinion angle so No, 3-5 degrees down should be avoided. Link bars with bushings could change the pinion angle very slightly. I made a video on bushing deflection if you haven’t seen it. So your pinion angle might then depend on what the vehicle is used for. You could have two identical vehicles with identical bars and identical bushings but one vehicle is 90% race and 10% steer while the other is 90% steer and 10% race. The race car you might tilt the pinion angle down a degree or so while the street car pinion is at zero. (Side note: The angles themselves don’t matter but the relationship between the transmission and the differential do. They should always be parallel as often as possible. So if transmission is pointed down 5 degrees, the pinion angle should compliment that angle. (5 degrees up) So when I say “zero” I probably should’ve said zero degrees difference. Hope that didn’t make things more confusing. 😬

[@MyLonewolf25]

Old video and series I know but wanted to kinda pick your brain. I know why you wanted to do parallel links but why not do a triangulated link setup? You can still get the same effective link length for keeping the pinion angle. Or at the very least do a semi triangulated setup with those upper links. You wouldn’t have to change much with your setup and could have kept the top links straight making them stronger while making your entire rear end a bit stronger

[@GarageFab]

KZbin basically makes all my decisions for me. This truck already had a Triangulated 4 link. I wasn’t thrilled with how the original builder did it and leaving it alone would not be a very entertaining video. Every modification I do is simply because it would be more entertaining to watch. I built a Watts link for this truck as well. Necessary? No, but a lot more interesting than a panhard bar. Just about everything I’ve done so far, could’ve been done an easier faster way. Luckily I like challenging myself!

Great videos, you’re voice is perfect for this and you should be a professional voice actor! On a different note, if you could d a specific triangulate 4 link video for classic trucks. I’m trying to put one in my ‘57 Chev with a GM 10 bolt. I’ve researched a lot but it’s hard to get the right answer, like should the bars be parallel? Or should the top be slightly downward to meet the projected lower bars line at the IC? I’m just building a daily driver. Thanks

[@GarageFab]

Thank you my friend! I went to a voice acting school for 4 weeks! I felt like I wasn’t getting much out of it for the money I was spending so I stopped. Maybe I was wrong! 🤔 I don’t know when I’ll be able to make that video especially because my next truck will have independent rear, but it’s definitely in the future plans. Until then, I’d be thrilled to help where I can. For your question specifically, will you be using adjustable suspension or coil overs? That makes all the difference in my mind.

[@sarblade]

@@GarageFab Well isn't that something! Yes, totally agree that the entertainment industry can be somewhat fickle that way. I am putting in coilovers, no bags, just basic, bought a generic welderseries link set, but because of the narrowness of the frame and the pumpkin being cast iron, the maximum angle I can achieve is about 24 degrees with the uppers going outwards from axle to frame. I may have to go in reverse and converge forward to a mounting cross member. These I can tackle but its understanding the best geometry for the setup. Oh, and I have a calculator, but I do not have my corner weights of the truck, as I have everything apart lol.

[@GarageFab]

Honestly when we start getting into corner weights, that’s going far beyond my knowledge of suspension design. I’ve never built a performance suspension and it would probably show if I tried. I specialize in the basics because that’s what I understand thoroughly. Meaning I can build a suspension that works properly, doesn’t self destruct, and has at least the traction and handling capabilities of most production vehicles. Because your building a street vehicle, I believe you would be still be happy with your setup if you reversed the triangle. I’ve done it several times with no complaints. Just understand that this is changing your roll axis quite a bit. (Roll axis is what the entire vehicle body rotate on when cornering and it’s determined by drawing an imaginary line through your front and rear roll centers) The roll center in a triangulated 4 link is the point where the two angled bars converge, and because your moving it forward that’s steepening your roll axis slightly. My argument is most people couldn’t tell the difference. Seasoned race car drivers could. Because you’re NOT installing bags, you can ignore how much I stress the importance of Parallel Link bars. That’s important in adjustable suspension to keep from replacing U joints every oil change. Your bars can be angled. A good rule of thumb is the lower bars are angled up slightly and the upper bars angled down in a way that if you drew an imaginary line through the bars, the uppers and the lowers would intersect somewhere between the grill and the center of your front wheels. This will give you a little added traction off the line that us bagged folks can’t have. Again, Mario Andretti would sense the difference between a parallel setup and the the angled setup mentioned above. If you ever want to shoot me photos, search @GarageFab on Instagram. Hope this helps a smidge.

I am building a traditional hot rod. I saw a 4 link on a traditional build I liked it, but it’s different . It has a bottom link tube at rear end bottom by spring end. The upper one is on top of rear axel 1-2” of the axel tube comes out of the “pumpkin “. The bottom link went straight to cross member. The top went to exact bushing the bottom used. Creating a triangle and they were actually connected with diagonally artistically Would this cause problems binding?

ok i gotta say the DOM vs Chromoly is sorta ass backwards. Chromoly doesnt need to be pre and post heat treated, so long as you buy it in the correct state {N}. DOM will work harden and begin to crack eventually. Once this starts you will be chasing cracks forever. 4130 was designed to be oxy fuel welded, its made for aircraft. keep the interpass temps good and you are golden. if you want to mig it run real hot but "weld dots" essentially stacks of tacks. in tig we pedal pump to keep the interpass temp down. as long as you dont turn it grey and crystalline itll be fine. for the stuff you build i cant see 4130 being worth the money. race car chassis? yeah, spend the extra dollars so itll last. play car? eh DOM is fine, just dont expect it to last forever. aircraft? yeah dont built it out of DOM.

Changing where the triangulated links meet will change the vehicle roll center a little and the roll axis a decent amount. Plug those into Google to learn a little about them.

If I'm build a track truck with about 700hp. Should I use a heim joint if my link bars are adjustable? Even if it's gonna be on coilovers static drop.

[@GarageFab]

Hey Derek! When you say “track truck”, are we talking an auto cross? The dragstrip maybe? Stiff components are certainly recommended to help put your horsepower to the ground, but Heim joints don’t last forever and are kind of high maintenance. If you need the truck to handle in turns, definitely go with Heim joints. Suspension components need to articulate freely. Straight line driving, you might be able to save some money and go with Delrin bushings. Still stiff but the articulation isn’t as important. I am not well educated in racing suspension. I’m basically regurgitating things I’ve read on the subject that I have no way of confirming or disproving because I don’t race. I’d highly recommend asking other people that are actually in the racing scene.

[@derektomokane2558]

@@GarageFab yes setting up for drift/auto cross. Can I use one bushing end and the other heim?

You absolutely can and it’s recommended to have at least one Heim joint if your bars are adjustable. Bushings on both ends will cause your locknut on the bar adjustment to loosen when the suspension articulates. One Heim will prevent that.
