OP
I bought it without a rear sway so won't be buying one now. It worked fine without it until recently. Good advice on the shock switch. I'll give that a shot.
Wouldn't it be asymmetric?FWiW, the AR can be set to different holes on each side and the bar will just balance out the forces. This is how we can make half step adjustments.

It is constrained in 5 out of 6 degrees of freedom.Only if something is constraining the torsion bar.
....
The only degree of freedom the bar has is to (6) rotate in the pitch direction (and deflect along the same axis). There is nothing other than the arms (and a negligible amount of friction) preventing rotation, therefore the moment applied by one arm must equal the moment applied by the other.
If the arms are different lengths, then they will provide different force to opposite sides of the axle given the same moment.Correct. And the force exerted on the axle is going to be the same on each side even if the arms are different lengths.
Not at rest, no. Because there won't be any moment to create any force. If the force on one arm is zero, the force applied by the other arm is zero.If I go outside right now and set the driver's side to the short hole and the passenger side to the long hole and make any adjustments to the link length, the Jeep will not lean from whatever happens to the sway bar.
Yes. But the fulcrum in in the center. That forces the fat kid to move in. But there is no center fulcrum to the anti rock. That forces the effective force to be equal on both sides.If the arms are different lengths, then they will provide different force to opposite sides of the axle given the same moment.
In order to generate one foot-pound of moment, a pound can be applied to a lever one foot in length. If you halve the length of the lever, you must double the amount of force to maintain the same moment. So if you have two opposing levers of different lengths, you must apply more force to the shorter lever in order to keep the moment about the fulcrum to be zero.
If you have a fat kid and a skinny kid on a seesaw, the fat kid has to sit closer to the fulcrum than the skinny kid to balance out the seesaw.
It should force the effective moment to be the same on both sides, not the force applied. At the fulcrum, net moment must be zero to prevent rotation.Yes. But the fulcrum in in the center. That forces the fat kid to move in. But there is no center fulcrum to the anti rock. That forces the effective force to be equal on both sides.
My apology for the 'fat shaming' I have now lost any hope of one day being President of USA.
