Heims, Johnnys, and Bushings: Different Types of Suspension Joints - Dirt Every Day Extra 

I love this...simple, straightforward explanation on the different joints and the basic pros/cons of each. :)

Thank you Fred. You hit it out the ball park , Very good segment , on these particular components an their function’s . It was nice to introduce in a way of your experience with these items an also a interdiction on the different class of stuff their buy you experience.

This is the most informative extra you've ever done.

Dude best educational video on the difference of these joints. Perfect explanation! Thank you

This info was helpful in a way for me bc I'm trying find a way to manage the power/ torque to my A arms. It's like my car can't keep up with my tires. It gave me a better idea on which joint I would like. Thanks

I remember a trick on the 1966 Chevelle Malibu SS 396, and other muscle cars of the era, was to drive 16d nails into the rubber bushings on the links. This was before heavy-duty replacement bushings were available. "Primitive Pete"?, you bet, but it stiffened things up and reduced wheel hop. A real budget trick... :-)

The fundamentals of joints Gotta say that's an awesome presntation. Have you done one on suspension geometry, and balance, control and handling characteristics of different setups. On purpose built setups. Similarities, diffrences and options.

Watched this video over and over.. Thanks, very helpful... Please tell me 1. the sizes of that black colored Johnny joints, the one that's fitted on the black control arm and the single one lying on the table ? 2. Factory size of bushings coming with a new Jk ?

I love the MetalCloak Duroflex joints over Johnny joints.. Self centering and 38 degrees of misalignment too. Plus they are quiet too.

Sounds like it's time to hit the dispensary - I'm thinking a pair of big ol' Heim joints and a nice mellow Johnny should be just the ticket!

Love the info, didn't know about those differences before. +1

My TJ has Johnny joints on its long arms(control arms) 5.5 inch sus lift and Heim joints on the steering arms! Flexes great steers great on and off road

Thanks Fred.

Dirt every day is so cool,I watch all the episodes and I don't and never have had a 4x4.

Plz do a video about track bars and death wobble

At 4:00 I believe the word you're looking for is damping. It absorbs and TRANSMITS all of the vibrations and shocks to the frame. Because it allows for greater articulation of the Axle. As opposed to a bushing which absorbs and DAMPENS those shocks/vibrations. But because it is a more rigid mount doesn't allow for as much articulation. Have you seen anyone using/offering an elastomeric bearing joint for off road use?

Thanks Fred

Good one Fred.

Didn’t know the Jonny Joint had rubber bushings in them. Great video.

What were those called and where can I get them? I'm building a pan hard rod in the future and this seems like a good choice

Great info

Are Heim joints the same thing that’s on top links for 3point hitches

Felt like he was just talking..not scripted to death... thumbs up!

nice explanation

good video explaining the difference. should also point out that a big reason heim joints arent really streetable is because of corrosion, and theres nothing keeping dirt out except for the tightness of the joint. if you live in the rust belt like i do, such exposed joints like that really arent an option for a daily driver.

More videos like this!

Could you share the measurements of the arms of a TJ

Rutledge wood from top gear has a lifted school bus. Noticed he has a single link arm on the rear. What is that for?

I love it

How do I get a hold of the people changing them out after every run lol? Sounds like a deal could be made there.

Nice!

Hey Fred just watched your newest dirt everyday extra on motor trend on demand about water crossings. You didn't mention anything about your axle breathers? Not super important?

Good video. One point: polyurethane makes an absolutely terrible bushing. Much worse than rubber,johnny joints or heims. They don't belong in a vehicle of any type

Fred manages to talk about stuff intelligently and not become boring.

How come control arm manufacturers don't send mounting hardware along with their products? Different control arms come with various sized bushings and steel inserts, some with inner diameters measured to fit stock, and others are expanded slightly which requires drilling the mounting holes in both the brackets and axles in order to fit a larger bolt through. This is a pain, especially if they're not going to send you replacement hardware to match! Also are the polyurethane bushings supposed to be able to slide about in their sleeves, hence the reasoning behind the lubrication so they don't bind and tear? I've had bushings just straight up fail during installation, not even road tested yet, so bushing design is a huge thing to consider if you're wanting ones to last daily driving.

BDS good stuff

I assume some guy named Johnny invented the Johnny Joint. Imma invent the Fink Link

Finally a good worth while [informative] video. Bout time! I was worried that Dirt Every day was pretty much done. After posting a RC toy video, barn doors, shitty version of a 4wd vehicle that already comes from the manufacture in a safer and Superior OEM 4wd version.... Thank you for making a good video, it's been a LONGGG time.

It's nice to see an informative video..but the shirt, when are we gunna see UA2017 videos!?

Seems most aftermarket suspension (radius bars) manufactures use plastic injection (2 piece) heim joints. Found them on a used 2018 RZR Turbo I bought. The bars were fine but a $14.00 heim failed and broke a $2,000.00 Fox Podium Gold series rear shock in half. It's what brought me here. Replaced all 6 with FK 3 piece heims ($29.00 ea) that will last me (non-racer) forever.

fred creates a vehicle for the top truck challenge

very precision lol

how about the metal cloak duroflex joint?

How many joints are in a lid?

I wish Fred would team up with the roadkill guys sometime for some sweet off road content!

Heims are shite for street use, they only work well as long as they are well greased, if dirt gets in them and starts grinding they start to rattle and drive you nuts. Standard bushings generally aren't too bad, PU is a nice upgrade thats still drivable every day

#RuffStuffSpecialties for me haha

We just need super grease that is 3times of thick as req grease to get some cushion back in Hymm set ups. If the bolt is prt of bracket that is C shaped & the bolt has neoprene bushing over it u hve as good a system w/ offset hymm big beef size as poss. The only wear prt u can change out & ultimate strength & flex & offset & mounting spot adjustment range(u pin the max travel the hymm can move on the Cbracket bolt. God/JBM

I bet hes seen some big joints

Why would you replace a Heim joint after a single race? Are we assuming that each race literally takes these components almost to the point of failure?

Great..

I actually thought Johnny Joints were nicer than heims partially because Johnnys are rebuildable and they hold grease better than heims unless you use heim seals.

Bungs🤤

Interesting. For a road vehicle use OEM rubber, near bullet proof and does not throw all the load back into the chassis. Though that 'Johnny joint' seems a good idea. Only though on big joints. Some OEM bushings are actually similar. Eurathane either binds everything up or if flexible enough falls to pieces, and will not bond to the inner and outer sleeves as the OEM rubber does. So you end up with components moving all over the place. Very bad! Ok as a simple bush where not a lot of radial movement is required. Panhard or Watts links as an example. It transmits a lot of noise however. And used in high load area does and will tear the brackets off the vehicle or even break suspension arms. Very BAD! Heim joints are not for the street either and in some cases will still bind suspensions as the suspension relies on some flex in the bushing to prevent bind. Though when set up properly is the way to go. Generally the cheaper the worse and get 'rattly' fairly quick. Good teflon lined ones are the go and not very expensive, under $30 for a 5/8/1/2 version. 5/8 thread with a 1/2 through bolt. For offroad etc use 3/4 hi misalignment. The 3/8 used in F1 are stronger than the common 3/4 used in Oval track or offroad, and cost 10 times as much and are replaced every meeting!

Being able to hve most durable, & adjustable joints w/out hving to buy diff lengths or remove to adjust that can b still mass produced is "best joint" God, but if racing reach for ultra light high strength go crazy, your racing.

B Rad!

Who needs suspension? Just remove them to lower your car, believe me it's safe

Please focus your camera more on the devices you are trying to show rather than focussing at your face. We need to see them clearly.

When is the world's greatest drag race 7

youtube made us relevant again... so ceo says how do we crawl back in to obscurity... and this is the plan in action

You are NOT the guy to describe joints...
