Running Without a Rear Sway Bar

jjvw said:
Can someone explain to me how the antisway bar locates the axle's position and defines its travel path? Or how an antisway bar stabilizes an unstable coil spring that isn't accomplished by the control arms and track bar?

I'm confused by the assertion because my old Antirock and my current Swayloc both use rod ends in the links. Maybe we need to be using bushings. 🤣

As I said before "unstable" has a very specific meaning.

Merriam-Webster:

unstable​

adjective​

un·sta·ble ˌən-ˈstā-bəl

: not stable : not firm or fixed : not constant: such as
a: not steady in action or movement : IRREGULAR

Fix the end of a leaf, twang it and it will be steady in all but one direction. Fix the end of a coil, twang it and it is unlimited in the directions it will move... thus, unstable.

But that was the point Jerry was making, I think. If the system allows the axle to move in every direction, instead of just up and down, I would call the unstable.

Can you explain how the antisway bar locates the axle and defines its travel path due to the coils being unstable in all directions? Because that's where people are getting confused.

Now attach a sway bar to the same surface the coil is fixed to. The unlimited movement of the coil stops.
 
Only in your theoretical world. If that was true well built rock crawlers wouldn't need or run antiswaybars like the Currie Antirock.

That was certainly not my assertion, because the sway bar does neither, of course. Your second point is valid through, as the thread did get a bit off track from the title - and I probably didn't help along those lines.

Touche.
 
I went with the swayloc. from what I understand, in on-road, it is locked and solid. for offload (simple mechanical switch outside on it) it is unlocked, but it is a torsion bar so that it still has some traction against the ground as opposed to completely disconnected. I had quick disconnects before, and I hated them.
 
I'll stick my neck out here and agree with Jerry about leaf springs. Twisting them (ie, when articulating) makes them stiffer so they resist flexing much more than coils do, and they are less likely to require a sway bar. People with leaf sprung crawlers have gone to great lengths trying to reduce leaf twist and allow more articulation.

I still don't see how front disconects are a hindrance and only used by newbies in slow speed crawling scenarios. I always thought you wanted as much articulation as possible when going over uneven or off camber obstacles and trails.

Front is rarely an issue, but too much in back can hinder traction by shifting weight too much.

There is actually such a thing as too much articulation.

I actually agree with @Jerry Bransford I just don't want to admit it

Disconnected gives you no roll control and unweighted (unusable) articulation.
Sometimes a little can help when you're off camber. Prevents you from tipping.
The Antirock gives you that little bit, yet when adjusted properly does not reduce travel.
