Why does the 2WD have a bigger front sway bar than 4WD? - Click HERE for Original Thread
slimmn
Just perusing the specs on honda.com, and noticed that the f/r sway bars for the 2wd is 24/20, while the 4wd is 23/20 (also the same as the mdx).

This may be more splitting hairs than anything, but I would think it' ll be the other way around, since the 4wd is heavier, unless I'm reading the specs wrong.

"Stabilizer Bar (mm., front/rear) 2WD (4WD) 24.0 / 20.0 (23.0 / 20.0) "

TIA

Since the 2WD is FWD all the time, it does make some sense to me that the 2WD front sway bar would be bigger.

While I don't know all that much about sway bars, I think a FWD is more susceptible to torque steer or the rear fish-tailing; a larger front sway bar must be doing something to counteract those negative effects.

Having a larger sway bar on the 2WD is interesting.

The larger sway bar is about $35 from Majestic Honda's website, uses different bushings but the same endlinks and bushing brackets.

I might try out the larger sway bar and polyurethane bushing on my '06 4WD. I was looking for my next mod and for less than $50, this may be the one.

Only $35 for the front sway bar? Seems really cheap. Also, where did you get the info about the bushings, brackets, and endlinks? If indeed it's only $35, it's worth a try. You planning to do it anytime soon?

Majestic Honda link. Just use the selection buttons and compare parts list bewteen a 2wd and 4wd.

Thanks for the info. I'm so used to paying high VW/Audi parts prices, even online, and this is welcoming news. Think I'm going to like this.

I was wondering if 1mm is really going to make a noticable difference? Are there any after market sway bars out there?

Hmmm. I like the way you think!

A 1mm difference in swaybar dia can make a difference, though subtle. I moved up 1mm in the rear of an old Miata w/good results.

A larger front bar will shift the balance slightly towards understeer, where the current balance is actually pretty neutral. On the positive side, though, it should help the car "change directions" more quickly (better steering response).

I have a hard time believing it's only $35. I'm going to crawl under my Pilot and see how easy they are to r&r.

Thanks for teh pointer.

Shifting the balance towards understeer implies that the front end of the vehicle would tend to
continue straight ahead as you attempt to turn - just the opposite of helping it to change direction more quickly.

^^ only at the limits of adhesion will it bias towards understeer. In normal spirited driving the front end will respond faster to steering inputs. I doubt many of us are going to drive the cars hard enough to slide them.

I spent a few years autox'ing, and will add that a stiffer front bar doesn't always mean more understeer, depending on how the rest of the chassis reacts to staying flatter through turns. More roll control is especially beneficial for cars w/strut type suspensions (like ours) for factors I won't bore you with.

I'm also wondering why the engineers at Honda spec out the size roll bars they did for the 4WD vs 2WD vehicles? You want to play test pilot? There's one way to find out.

These engineers are such idiots!

Maybe, just maybe, the vehicle dynamics between the two cars required a different size roll bar to compensate for the loss of 200 lbs, or so, in the rear of the 2WD Pilot.

As Dirty Harry would say: "Are you feeling lucky?"

Dad? How'd you get on this forum, I thought we took away your computer you grumpy old fart?!

For what it's worth, the factory manual for my '06 says you need to drop the subframe to replace the stabilizer bar, front or rear. That doesn't sound like fun, or worth it for a 1mm thicker swaybar that will have an unknown effect on suspension dynamics. You may be able to get away with not dropping the subframe to just do the bushings, and the swaybar links are easily replaceable without extra shenanigans.

Sorry to pour yet another bucket of cold water here. :)

Thanks, IMO if it's more than 10min and $50 I'm not interested. This sounds like way more than 10min :)
