One good way of demonstrating how sway bars function is by standing straight with legs slightly apart. When you bend one knee, you tend to become off-balanced as the other leg is still straight. Now if you have a sway bar, that is connected to both legs, if one knee is bent, the sway bar would force the other knee to bend too, thereby keeping you balanced and your body upright.

When making a hard turn, outside suspension compresses and the sway bar compresses the oposite side and Squats the Car keeping both tires on the ground

This is the first video that actually broke it down simple enough for me to understand. Thank you!

You are the only one who made me understand how it works, and I don't even speak English very well and I still understood you, there are other videos on KZfaq where they only show how it works on one side of the stabilizer bar, thanks for sharing the video, it helped me and It's what I was looking for.

I did not realize that the sway bar causes the vehicle to squat! Nicely done, 👍

Really well done. Thought out and well delivered. Thanks!

Excellent explanation. Thanks

Great explanation in less than the six minute mark it becomes clear how the bar works 👍

Finally got it. Thanks! Can't believe there are so many here on youtube who can't explain it the way you did. Sometimes even straight up not true lol

Succinct... brilliant explanation! Thank you

Thank you so mutch! So far it's the most clear and best to understand video on sway bars I came acros. I'm trying to deep down in the theory of vehicle dynamics for sim racing, and this video helped me the most in understanding sway bars and how they work. Thank you! :)

Very clearly explained...thank you!

Good basic, understandable information. Thanks.

incredibly helpful. thank you

thank you so much for the explanation, between all the videos I have seen so far, this is the one I finally got the working principle.

Thank you for your time This has explained a lot to me.

Good and clear explaination,. Thank you

THANK YOU! Finally some good, simple explanation

Super approachable explanation for a total noob. Thanks.

Explained very well. Thank you.

Great video! Explained perfectly.

Had to have both sway bar end links replaced today due to worn bushings. It eliminated a clunking sound that I had had for years but never understood where it was coming from. The new end links fixed the clunk... and after watching this video I now understand how sway bars work and why they are needed. Thx for the info. 👍

Great video man!

Thanks man, never really knew what these were for, always thought it was to keep everything secure structure wise.. now I understand, thanks again 🙂

Wow!!! Perfect explanation thank youuuu

simple and on point

thanks bro! great explanation

Great video thanks

Thanks for the info man, I like your style of channel

Thank you!

Exactly what I was looking for 👍 Clear and explained well how it works!

I lked you explanation. Just a little confusing, but for us being able to visually see how it's working, how and why the components behave in that particular way was really helpful. Thank you

THANK YOU!

good explanation 👍

Great! Thanks bro!

Thank you man,I got it.

Very well demonstrated and explained especially different perspectives and tuning. I had the same perception that the job of the sway bars can be done by stiffened suspension. So why use them at all? You're the first person probably who explained this. Thank you. Cheers 🥂

Great video, what effects on bump steer will a sway bar have?

I enjoyed it would love more on sway bar even animation

The outside suspension compresses as inside suspension gets lighter (expands). Sway bars are engineered to resist & balance asymmetrical compression to more desirable amounts via a twisting force as a feedback-loop. A turn transfers _x % of load:_ The CoG-change + centripetal forces' sums to dynamically spread across an axle transferring more load to the outer wheel. The law of conservation requires that (on avg) the sum of weight across an axle be equal to the weight over the axle. The center of gravity's transition however, can be mitigated; this is to maximize PSI over the inside-tire. While the PSI over a contact patch determines friction between most materials, tires are different: As force increases over a tire, it will provide a lower 'ROI' of the weight's investment. As force decreases over a tire, it provides a HIGHER 'ROI' to the weight's investment. (this is one way a sway bar can be helpful). You want roll, squat & dive; you just don't want all its travel consumed (except F1 who use bump stops). Tires also act like shocks; higher PSI = stiffer 'shocks' and lower = softer. A sway bar thick enough to resist all torsion would cause both side's suspension to compress equally. But apparently, it can also make the inside wheel lift in some circumstances (rumor?). A sway bar's utility is increases agility: Stiffer suspension + sway bars TRADE stability for peak traction. The weight experienced by either side is a function of Physics Laws, and: THE LAWS OF PHYSICS ARE NOT SUBJECT TO REPEAL NOR SUSPENSION

Very good explanation. Do a video on the function of the sway bar link

HAHAH Ohhh... i see now. You made it so simple :) thank you!

very good video

Thx

After years of wondering what's that bar used for, now I do understand. Thanks. Good explanation, but it would be better if U had a little car sample, putting in front of U to show the car's direction, tilt angle...

One thing to mention, stiffer springs are not entirely a replacement for a sway bar. The sway bar does *nothing* when both tires are compressed the same amount, for example, on a hill, speed bump, or elevation change, the sway bar doesn't do anything because both sides are coming up or down together on their own.

So basically the sway bar job its to compress the struts but not decompress?thanks for the video very clear simple understendable

so when u "upgrade" a front or rear sway bar, are you just getting a thicker metal or different type of metal so that it doesnt flex as much? also, for a front wheel drive car would it be a good idea to get a stiffer rear bar to reduce understeer?

Hi Eddie, What happens if you change the positions on a adjustable swaybar from side to side. So you set one side in the 1st hole & the other side in the 2nd hole. What will be the result & why would this be an advantage or not?

I have some questions...I recently lowered my car, with a suspension kit, and at the time of doing my research before buying it, I came across 2 mods I don't think I quite understand: adjustable drop links and different size bushes for the anti roll bar. Would appreciate the enlightment lol Also, I have a fwd car with a solid rear axle, does that mean I have a lot more room to stiffen up the front at all?

thank u for information sir ....really u r a good teacher...the another benefit of sway bar may be improved negative camber of the outer wheel .if the wheel go slightly up then negative camber also increased..am i right ?...i do not know pls replay me

You look like the Beaver from Leave It to Beaver.

in the most simplest explanation... when the car turns to the left , the left side of the vehicle starts to LIFT UP and the right side starts to press down. which causes potential roll. with the sway bar, when the car turns to the left , the left side of the vehicle starts to LIFT UP but the sway bar tries to keeps it from doing that because its solidly connected to the RIGHT. pressure from the right help keeps the left side down through the sway bar.

The only thing I would say is over steer and under steer are fundamentals of steering and suspension geometry, so the anti roll bar does not effect thise principals. What you're actually describing with that incorrect term is a loss of traction as you have exceeded the coefficents of friction on the tyre! Yep, a mouthful, better described as skew or a skid. Any loss of traction is technically a skid. 🙂 The best way to think about over and under steer is where the Akermann intersection is (where the lines from KPand steering joint cross) if it is before the rear axle or anti-akermann, it will under steer, if it is behind the axle it will over steer.this will be measurable and seen at 1mph (you need to avoid tyre deformation to get a true result).

so the sway arm is connected in a way that shortens the length of the struts evenly against lateral forces of the of the body movement, by basically compressing the strut on the opposite wheel to keep the car level through a turn.

👍

So I lowered my car a while ago and found out that sway bar links need changing as well. I used BC Racing coil overs and dropped it about 2” total, and it feels just fine. I want it to handle, that’s the thing. It seems to be great in corners, considering I’ve pre-loaded both sway bars by not shortening the links how would that affect it?

gloooks my guy

Can be fit 3 pieces of D bushes at the back of sway bar? Handling better?

I backed into my 99 Nissan Maxima with my 06 Town and Country. I struck the front fender of the Maxima behind the wheel with the rear corner bumper of my minivan going 5MPH. I wanted to replace the front suspension of my Maxima when I discovered the sway bar link broke free from the control arm. What kind of damage could have done to the sway bar during a light impact?

Been having an issue with the sway bar in my 2011 Subaru wrx. Should the sway bar be able to move side to side in the bushings?

I am allowing a company do do some R&D on my stock Q60 in which they want to create sway bars... I do not know anything about this nor would it have been something I would change on my car. I was all about it but having second thoughts. Any advice?

Can anyone help with a fwd oval track McPherson strut sway bar set up. Thanks

Great. Understood the black magic now..

I race non suspension go kart I see what the bar does is pick the inside tire up but can that make the vehicle dump weight on the inside tire?

So when one side is compressd It works against the Spring on the other side which increases stiffnes on the compressed side. On something off road that seems like it would limit your suspension a lot

Hello teacher , I am the one that described my Kia forte 2019 (ONLY 16000 miles ) with chirping sound in your other video I hope you remember me ??? i told you that when i turn the car aggressively into right ( especially in bumpy road ) i hear the chirping noise in my driver side) . you kindly advised me that i would tell the Kia dealership to check my "sway bar bushings" before they change my struts . Today , I just found out they did NOT changed my sway bar bushings because the technician told me that he ruled it out ( the sway bar bushing's potential problem) by disabling "the sway bar from the left and right end of the car ' and he said that he could still hear the same chirping noise when he drove the car, after disabling the sway-bar , so IT COULD NOT BE THE SWAY BAR BUSHINGS .... Is disabling the sway bar from tiers rule out the problems with " bushing rubber ) ??? I think they were lazy and they did not want to change my sway bar bushings ...After watching this video , I demanded the kia dealership to change the bushings ....ARE they telling me the truth ??? Can they rule out the potential chirping noise coming of the sway bar bushing by disabling the sway bar form right and left ends ???? base on your great explanation, i told them the bushing still CAN MAKE NOISE even if sway bar is disabled . dear teacher , am i right ???? ( by the way they did change the strut bearing / or mount and they did spray with silicon grease all my bushings , EXCEPT sway-bar bushings ) ) I am gong to see then this week ( Thursday to change my sway war bushing hoping the chirping noise goes away )

Do sway bars work better on fwd or rwd or both?

So the holes on the swaybar is the firm option the hole closer to the bar or the end? you didnt explain that part.

My Chevy Impala’s front sway bar rusted off and I’m replacing it with a stock one and calling it good lol

that means you need to lubricate the rubber bushing?

What dose the rubber bushing do

I recently changed wheel size on my Chrysler 300 18220 s now my tires are wearing crazy my front driver sideis wearing on the outside real bad real fast that passenger side has a little wear on the outside and the rear passenger is war real bad on the inside and the driver rear is it's okay well that have something to do with a sway bar

In short.. both spring is sharing the load when cornering

3:19 if you dont need a preamble

I am confused at 7:22 because here is a video saying the sway bar can be twisted like that: kzfaq.info/get/bejne/hKx3nr1_17S4eXk.html

was just looking for that new sway song, Incidentally put in new neothrane bushes, hated it straight away. Buy a bigger sway bar match them Front and Back. Rubber is much better

the clamps on the bushing it should be very tight no movement whatsoever. The reason why the sway bar is a an actual spring for each side it’s not meant to move on the other side because the spring on the strut will push it down to stabilise that side. so the middle of the sway bar is not moving. That’s my theory!!!! Thanks

I think you're too focused on the outside wheel in your explanation. The way I like to look at it, your wheel assemblies are always in some state of compression. They are floating. If their load is lightened, the suspension will expand, if their load gets heavier, the suspension will contract. So basically what the sway bar does is creates a connection between the right and left side suspension. If one side compresses, the bar twists to compress the other side. Now you are accurate in saying that this does serve to correct the outside wheel, but that's actually skipping a step in my opinion. The more important feature in my opinion is the compression of the inside of the turn. The twist of the bar pushes the assembly up (or rather, pushes up the equillibrium of your tire assembly and suspension) and this allows the inside to be closer to the ground which helps to correct the weight distribution problem.

Starts 4:56, 6:08, 7:22

Instead of a sway bar, has any car manufacturer company created a suspension that makes a car body bank towards the side it is turning on.... Similar to a motorcycle when it turns....

for the love of god man

What causes engine vibration. My tweaker sister has hired her dope head mechanic to "repair" my dad's car and bill him of his money though he is a senior citizen and it's a criminal charge. Response would be great

To uhhh ahhhh ahhhh ahhhhh uhhhh allll alllll olllll sayyyyy sayyyy sayyyyy😂

You got lost. I think one side try to go down but the other resist. So the body stays as level as possible

is there something that is better than a sway bar? say electronic suspension

This video could've been 30 seconds long and more effective 🤣🤣

You could have said all of that in 90 seconds.

What a confusing mess

repeat yourself way too much. you could just explain this in a few sentences.
