Daily driver with no front sway bar?

Let's see that "Fairly simple math" then.

 

I'll give a little simple math. 60,000 miles + aggressive driving/ 3 years = 0 rollovers
In my opinion there are many many more factors that cause rollovers, or any accident for that matter, than the sway bar.

 

Sure. Its nothing but simple addition and subtraction problem. A vehicle without a sway bar requires X pounds of force acting laterally on the center of gravity to lift two wheels. Pick any value for X you want. A sway bar provides resistance Y to that force by transferring forces from a corner of the vehicle that is experiencing an increasing load to the corner on the same axle of the vehicle that is experiencing a decreasing load thereby resisting the lateral force. Pick any positive value for Y you want. So, X equals pounds of force required to roll a vehicle without sway bar. X plus Y is the pounds of force required to roll a vehicle with a sway bar.

So you are either trolling me here or you have absolutely no idea whatsoever how a sway bar works. You choose. I'll give you credit and not consider the third option which would be that you are simply mind numbingly stupid.

 

I have 600lb coils... and I maybe noticed it for like half a day, but now it just feels normal. Granted, I haven't had to do any evasive maneuvers since then.... For normal daily driving it's perfectly a non-issue.

I considered putting a sticker on my truck.... but thought it might be a little tasteless. I just like naval history.

 

Sway bar aka fun limiter, is stupid take it out going on almost 2 years without it best free mod ever

 

Ran without one on my 03 Tacoma for 6 or 7 years.. I never really missed it and I drive a little over 400 miles per week on highway. Icons, armor, winch, canopy etc. No Moose were harmed during this time!

 

From what i read that

"(a)Axles. No axle positioning part shall be cracked, broken, loose or missing. All axles must be in proper alignment."

Sway bar is not an axle positioning part. That would be something like a leaf spring, control arm, panhard bar, trailing arms.

 

This sounds about as applicable to real driving as a rotating centrifuge test.

I'll applaud you for pulling the letters X and Y out of your ass, but I'm afraid that you've fallen well short of the relevance marker and well beyond the actual point.

I would like to see some proper testing done so as to ascertain in what scenarios there is a greater propensity for rollover between sway-equipped and sway-less vehicles. I would imagine that upon flat ground, vehicles equipped with a sway-bar would be more likely to slide or spin and less likely to rollover. I would also imagine that in off-camber situations, a sway-less vehicle would be less likely to rollover. However, these are educated guesses, hearsay if you will.

I would like to see some real data. Why? It interests me. Data is nice, because unlike Billy-bob telling you how many years his DD has had an Oompa-loompa welded to the hood, data gives you a point of reference for forming a hypothesis.

Having looked into it a bit, there doesn't seem to be much information on the subject. There is plenty of hearsay/buttdyno/IMO nonsense; yet, inquiring minds desire better.

As for ignoring the forces at play in the real world, there is plenty of centrifugal testing nonsense in this pdf if you are interested: here
It may interest you to find this out, but since this report from 2002, the DOT seems to have failed to come up with any reasonable method for assessing rollover propensity between vehicles.

Cheers

 

I tried for a day with sway bar removed after doing a full OME kit with 884's. I didn't like it. It felt way too loose - like driving a 96 Tahoe. I also have a slide-in camper so I don't want to be too loose when I'm carrying a high centred heavy load like that.

 

I feel I already know what some of you will say, but I was wondering if any of you had some input about me removing my sway bar. I have fox 2.0 coilovers which I think are 600lbs coils. I also have a bit wider track width than stock with 1.25 wheels spacers and 4.75 back spacing wheels... Please no shitstorming me!!

 

I don't know how anyone can be unsure if sway bars (AKA anti-roll bars AKA stabilizer bars) actually work to limit body roll during lateral acceleration. Its mind boggling. Why do you imagine that automotive engineers have been installing them on vehicles for nearly 100 years? Or why they spend time and money carefully engineering them for each model of vehicle?

 

I'm not aware of anyone that doesn't know sway bars allow a vehicle to sustain more lateral Gs without rolling over... when lateral force is the only force present.

What I'm interested in is seeing some empirical evidence that may help us to ascertain what situations sway-bars/lack-thereof cause more/less rotation and more/less roll.


Are you one of those people that is desperate to prove others wrong or to show how right you are? That is how you are coming across. I solely stated an interest in seeing data from tests that might shed some light on what scenarios favour sway-bars or lack thereof.

 

educated guesses ? nope, doesn't look it by what you've been dribblin on the forums.

this scales up, so you can test this with a toy car if you want

these topics below I learned in grade school, and for me and most if us, we can just look at the mechanical connections to an anti-roll bar, realize it increases spring rate of the suspension, and in our minds conjure up the basic function and role it plays, and it is clearly evident that it is grade school science, no need to explain if further, lay it out, do the maths. Though you are free to hammer on your keyboard and DEMAND specific answers. LOLOLOL

-it reduces tendency to roll over, especially on paved roads in normal traffic

-it reduces tendency to roll over in emergency maneuvers

-it makes the suspension stiffer and harsher

-it transfers lateral forces from one side to the other

-it can interfere with articulation off-road, which is why peeps disconnect them off-road, they aren't really needed off-road when crawling around the boneyard trails, and removal can increase traction when at extreme angles, but otherwise it will reduce roll if connected

-on-road when VSC is active, know that VSC is programmed with the mathematics of exactly how much spring rate that sway bar has (along with every other fact about the vehicle such as COG and speed/angular attack..etc. remove it and now VSC might not be able to correct, or it will over-correct, if/when it kicks in


In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

inertia. In physics, the tendency for objects at rest to remain at rest, and for objects in uniform motion to continue in motion in a straight line, unless acted on by an outside force. (See Newton's laws of motion.)

Center of Gravity Center of Mass
A point, near or within a body, through which its weight can be assumed to act when considering forces on the body and its motion under gravity. This coincides with the center of mass in a uniform gravitational field.

An anti-roll bar (anti-sway bar, sway bar,stabilizer bar) is a part of many automobile suspensions that helps reduce the body roll of a vehicle during fast cornering or over road irregularities. It connects opposite (left/right) wheels together through short lever arms linked by a torsion spring.

 

This is hilarious please continue

are what you guys looking for.

Two things are pretty certain:

1. Most folks won't ever need to make an avoidance maneuver like this, although I know a guy who did, while he was driving a BMW.
2. If you remove the front sway bar, the Tacoma is guaran-fucking-teed to do as poorly or worse than that Hilux did.

Bottom line: if it's a "daily driver that sometimes goes on trails" - leave it on. If it's a "trail rig that also drives on the street" go ahead and take it off.

 

Although not a comparison of sway-bar/no sway-bar, at least you didn't break an arm patting yourself on the back for regurgitating the first two sentences from wiki pages on the laws of physics.






I'll now go back to drooling on myself and conducting sway-bar tests using toy cars.

 

when someone says I cannot find any info on this since 2002 and post up simple garbage theories
all I can do is hope to show how ridiculous things are by being ridiculous myself and either post an LMGTFY link or copy paste wiki articles.

Now I am punching myself in the face, BRB

 

This sucks. I took mine off years ago and I still can't get the truck up on two wheels. What other mods does that hilux have? Diesel? Hybrid? 8speed auto?
