It's amazing how awesome and consistent your content has been throughout the years. Maybe now you have a lot better body language and presentation, but the awesome content has been there all the time!

[@BwanaQixa]

I am here 12 billion years later, and loving you even more! 😊😊😊

[@Creeperboy099]

All I knew about this before was that 1. It is really good 2. It uses 2 control arms

[@mars3554]

A lot of mechanics don't know much about suspension either. Although double wishbone is a subset of "multilink" suspension, multilink typically means there is an additional connection from the hub to the chassis (in addition to the double wishbone) that allows the toe to change so when the wheel moves up and down, both toe and camber can change.

[@ekner]

Great videos! I'm a kart mechanic and all-round suspension geek, and it's a great pleasure to watch your videos. Very basic, yet informative and straight to the point! Way too much suspension talk is about "lowering" or other styling terms, which most of the time just ruins the ride and handling.

[@samdavis1228]

Your videos have come a long way

[@juliaellis745]

I just found your channel while looking for videos for a visual representation of things i have been learning at work on company test to better explain to my clients for repairs and i love this channel

[@Clintpoon]

I have learned so much from your videos! It would be cool if you did a video giving a brief overview of who you are!

[@Dave-dh7rt]

He has so much more energy today!!! I am so glad your channel is doing great now!

[@jaganmangat1989]

searched for double wishbone nd yours is the first result on KZbin! Kudos!

[@WHATTHEFUXYY]

thanks for helping us out man..seriously

[@EngineeringExplained]

Canada thedot Very welcome!

[@EngineeringExplained]

Excellent, great to hear. Hopefully new videos once a week keeps you endlessly educated. :)

[@can-cruiser]

Thanks for the video. Very educational yet simple to understand and follow. If I may add a comment, in some applications, a lever-type shock absorber can function as both a shock absorber and the upper wishbone. Examples are found in vintage European cars from the 50's to the 80's.

[@josephmaxwell7826]

So far I've rebuilt a transfer case on a Chevy K10 and the rear end suspension on a Lincoln LS thanks to your videos. You are super - thanks for the visualization.

[@swilson7674]

Joseph Maxwell I have a lincoln ls that needs work. What did you do for bushings and shocks. Any advice is appreciated

[@cybertree]

Your explanations and drawings are perfect +Engineering Explained , I'd seriously be lost without most of your videos =D. For me personally I love how your drawings are slightly exaggerated like you mentioned, I'm a visual learner and that helps me get the idea big time. You're awesome!

[@ThomisticAmerican13FOX]

Great video, no matter It's age. My old Honda Prelude SH had double wishbone all around and was a fantastic ride handling wise.

[@ranjanjeetsharma]

you are doing an awesome job.may god bless you. also a suggestion: please add some real images of the component you are explaining for better connecting and understanding

[@EngineeringExplained]

That's so awesome to hear!! I don't know what class you are in, but perhaps one day I could skype in and chat with your class. Glad you found it so helpful, best of luck with your project!

[@GMAN420BC]

OMG this is old and you look young ! Not that it matters because you present the information in a way that can be u derstood by a high school dropout such as myself. Glad you kept making them from here.

[@themotorlawcompany4673]

Great vid. Clean cut, simple, and most importantly; short. Thanks for not rambling like so many other youtubers.

[@shreyasshanker858]

please do a video on bump steer, roll steer, passive steer etc.....really love your videos man...they taught me a lot

[@vasiq44]

Excellent! But I wish you did more of that in the end where you physically show the parts on an actual car. Good work nonetheless :)

[@TheSUSHENDER1992]

I am Starting to admire ur knowledge as well as your way of teaching..!!..!! Kudos..!

[@cliftonoyarzo4025]

Negative camber also happens with droop. Good explanation here!

[@danielnorton2123]

Excellent explanation - which is what I’ve been looking for!! Great use of a whiteboard and diagrams - ‘old technology’ that can work wonderfully!!

[@K_Sadek]

It's great that you actually put these 10 seconds in the end of the video to show how a real one looks like...definitely makes it stick to your mind.

[@lidge1994]

Aww, young Jason, so fresh faced and inexperienced! Ever thought you'd be one of the most well know automotive channels some day?

[@EngineeringExplained]

If you have an adjustable camber upper control arm, then yes, it's very simple to adjust. It's a simple and effective suspension set up that offers minimal camber change with suspension travel.

[@jilee4471]

Thank you for the great vid. Finally, get to understand about the double-wishbone. Noticed lots of great handling cars use this suspension. My recent curiosity is Vette's leaf spring. I heard lots of pros(lighter etc) but no one really talks about cons other than design is old. I really like to hear your thoughts. Thx again.

[@EngineeringExplained]

Great to hear! Thanks for watching!

[@Tom-ol1ik]

great video! explained perfectly, ive watched allot of your videos and im just amazed by the amount of great content on your channel even almost 6 years ago :)

[@sabercruiser.7053]

YES INDEED HE DID.

[@hashimola]

Great videos. Correct me if I'm wrong, but I would like to note that the unequal arms on the double wishbone are also good for cars that are riding low, since the compression of the suspension tucks the wheel in and away from the suspension.

[@rt1566565]

i can watch this all day, very informative and understandable. am glad you did this

[@EngineeringExplained]

Yes, regardless of front or rear. The lengths are altered to attempt to keep the greatest contact patch on the ground through all motions of the control arms.

[@UdayKumar-pb4ol]

hey ..u explained the concept and functioning of the Double wish bone suspension and i love your way of explanation....can u explain the calculations to construct the supension..

[@lenchristopher]

I'm on a journey to watch all the videos on your channel. Keep it up! :)

[@mrlifted365]

Great explanation thank you, I just got a supercharged jaguar xf so I need to know everything

[@uRea1]

Time saving and Easy to understand...!! Like your videos they were pretty Awesome bro. If You can go next for the Rockwell suspension,I will appreciate your work.

[@tothiusbentheum2071]

I watch some of your video's and you do a good job, so I have one for you. Being a mechanic all my life, I tend to question how things work inside and out so I can better diagnose them. I had to figure this one out on my own years ago, but still to this day you can't find any info on it? It's the Mercedes front lower ball joint design. Two lower fixed arms with ball joints side by side at the spindle. The first thing when I seen this on the rack was how is this not binding? 90% of mechanics has no idea or even question it and don't want to know either?

[@blitzeral8620]

interesting. so on a offroad gokart/dune buggy camber has 2 benefits, keeps the wheel returning straight and helps in turning. thanks man your vids are awesome!

[@rzozaya1969]

I really like your videos, they're very good and easy to undertand.

[@edwardtrickett6064]

Content as always is excellent but your newer videos have much better production values Thank you for explaining things so well

[@OldElvis1927]

Nicely done. Very easy to follow. Thanks.

[@EngineeringExplained]

Good idea, I do have a video replacing the thermostat in my Integra if you're interested, I go over the basics (briefly).

[@e30bmw41]

Great videos! can you explain semi trailing arm rear suspensions? mostly why they were abandoned and why letting off the throttle while banking causes spin out, snap over steer. correctable or can problem it be minimized?

[@Nicosh1471]

Another great vid! Liked the clip at the end, helped to put it more in to perspective, thanks! :)

[@DJWhitetailfluff]

Ford used Torsion bar suspension in their late 1990s to 2011 4x4 Ford Rangers. Mine included. : 3 The 2 wheel drives just got coil springs.

[@stevenc184]

Outstanding work young man, thanks!

[@ajfam871]

Keep the vids comming thanks a bunch. Can you do a video on inline engine versus flat/boxer engine versus v-engine(v6) maybe separate vids explaining pros and cons.

[@francisanand8713]

Very nice video bro,keep making great videos.DOuble thumbs up.

[@streetglidetexas]

Thanks so much for this video. It really helps explain. What would be the benefit of putting the shock/spring on the upper vs lower and vice versa?

[@hellsgunz1006]

You my friend should do a video on multi-link suspension. Great vid.

[@morfaces]

The spring and or shock location is versatile, quoted from you video post. What location would be most efficient to maximize suspension effectively. Different locations for different surface purposes, hence I'm referring to tarmac. Nb, informative.

[@RaamiKala]

hey EE i really like your vids. they help me understand how my car works and how better to look after the different components. my rx8 has an independent double wish bone front suspension system with independent rear multi-link. could you do a video explaining how mulit-links works and the pros and cons. could you also do a video expanding on struts as i have an oem tower strut in my rx8 and i'm finding it difficult to find an aftermarket part that looks decent. i would really appreciate it.

[@EngineeringExplained]

Excellent, glad to hear!

[@pawanmunnangi7128]

Thank you so much for your video. You teach really well!

[@reneyau09]

Great video, one thing I don't understand is why some lower control arms in this type of suspension doesn't look symmetrical, meaning the ball joint is not exactly on the middle between both bushings

[@LamontwOw]

All the videos are great!

[@Charlie1821]

7 years later he still has the best explanations

[@toxigenegoober]

Keep em comin! Good explanation as always!

[@EngineeringExplained]

@caquillo07 G35 probably does have a higher insurance like the BMW, yes. But when I've talked with mechanics and asked similar questions, most have referred me to Nissan simply due to reliability (and Honda, of course, but you seem to prefer the 35/350). As far as the internals they both share the same parts, so I don't see cost being too great an issue, unless there was body/interior work that needed to be done.

[@vucci8378]

you are a intelligent young man. keep making more of these

[@fabiorobertoalonsode]

Thanks a lot! Very Nice explanation!

[@adityasanghvi4143]

Hey! Amazing video! I just wanted to know the difference between a "double wishbone" and an "independent double wishbone with coil spring over shock absorbers"? Thanks!

[@EngineeringExplained]

You may be correct, though also it's likely possible to have it go various ways with different geometries. Sketching it out on a sheet of paper in front of me, it seems that keeping it fairly neutral wouldn't be too difficult.

[@mackaycadell2783]

@EngineeringExplained It was a Ford Exploder, stay fantastic my friend!

[@Thekshat]

very well explained.... thanks a lot.

[@stigfcf9631]

Great video due, keep up the good work!!!!

[@chigbomgbemene8234]

Thank you so much for this.

[@zaqueumacedo5674]

Well done! Keep up the good work! Tks!

[@EngineeringExplained]

@mahendrapurigoswami The camber (relative to the body) changes when the body rolls. The body rolls while turning. I know this is difficult to visualize, as I had troubles myself trying to sort it out. Though consistently I've read this is the reason for shorter upper arms.

[@lunananaharu2412]

awesome videos, thank you!

[@NorwayGokart99]

Really interesting video! What about trying to convert the front and/or rear of the integra to double wishbone? Or is that too expensive for a video online?

[@mthxjzz6462]

I ´ve learned something. Thx! (Subscribed)

[@rajatmondal3547]

Brother,you are great.

[@andrepit1331]

Hello ! Nice videos, i already watch most of them . I have just a question , witch are the advantages of double wishbone suspension comparing with multi link? Is it easier to ajust camber for example?Thank you

[@mebinphilip463]

can u put a video on triplex suspension? btw awesome channel....

[@ohboy4364]

Thnks bro.... It will realy help me in my exam..

[@parthpallan5760]

beautifully explained man...just one question....what is the difference in the cushioning effect when shocks are mounted between the 2 control arms and when mounted between the upper control arm and the chassis???

[@EngineeringExplained]

Thanks!

[@tummiehond9432]

cons for unequal arms should include: Depending on the "dampening" varying response to steering. If the car would be driving such that thesuspension is dampening out a bump in the road the wheels are somewhere in a (very) high position while thet would be in a really low position when you drive through a hole in the road. If then the wheels either goes up while alreadyl being up or goes down when it already is down due to the roll you end up at the point where the suspension travel stops. You need to avoid roll by using stabilsers or by using a double wishbone! Double wishbones have the advantage that they roll less which is because wheels stay aligned better and thus roll would mean the car liftsbecause the tyres surface tilts thatthen means the spring gets the load while the other side gets a smaller load (the total force on the springs and shockabsorbers equals the car weight always (neglecting the acceleration of the body that is required). Please look at my picture and ask yiurself what that teaches you? (The answer natuarlly is that if you think about it, it is only logical that we tend to pay more attention to car supsensions, because we tend to see them more often!)

[@EngineeringExplained]

They are potentially the same thing, the image I've drawn in this video is both of those. The coil spring over shock absorber simply refers to how the suspension deals with springs and dampening, nearly all vehicles use a coil spring and shock absorber, and most have the coil spring over the shock absorber (around it).

[@williamaurnerjr.7328]

I'm making a dune buggy, and this helped me so much I can't express my gratitude to E.E

[@FarmYardGaming]

How's the progress?

[@StalkerX86]

Thank you! Just an hour ago I was thinking about is it give anything good to shorten upper or lower arm.

[@joachim3562]

Appreciate a demo of Mc Pherson Strut suspension system

[@mayurghadge4039]

will you please make a video on trailing arm and pros and cons of it?

[@isakamuwanga3365]

The new Mercedes G class employs a double wishbone suspension as opposed to the rigid axle which off road enthusiasts have come to love. Kindly advise which is a better setup in terms of functionality and durability for this car?

[@EngineeringExplained]

Correct, it depends a lot on the spring/dampening rates.

[@amrahmad3536]

Great video, thank you

[@SzymekCRX]

Keep up the good work !

[@161BMW]

Good video I learned something great.

[@crux314]

[@giulianovargas9253]

Hi! The Suspension Playlist is great, but you should definitely do a remake, since most of the videos are quite old and the audio quality is not as good as your new videos.

[@4G12]

SLA suspension allows more camber recovery, but usually by increasing the roll centre height. The car would roll less, but it does not decrease weight transfer signficantly. In fact, it can cause weight jacking, which can be bad for stability. Another issue is that unless ride stiffness is high and/or antidive/squat is high, better camber recovery when corniering will come at the cost of compromised longitudinal grip due to compromised camber. It's a matter of balancing tradeoffs.

[@mohsen1374]

Great video series and awesome channel! could someone just explain how the shorter upper arm leads to positive camber on the inner wheel when turning?

[@MiguelMedV]

_Oof,_ super late answer but anyway, the shorter upper arm leads to positive camber on the *outer* wheel, and more positive on the inner one...

[@FarmYardGaming]

I don't even get bored watching these videos no matter how complex, yet I get close to falling asleep learning revising something simple in school

[@EngineeringExplained]
