The bar inside the rear axle does act like a sway bar. Take one wheel and tie it to the ground, lift the other up. What is twisting? The cross channel. Now add a tube/bar into the channel. Harder to twist, right? So now the two wheels are trying harder to stay at the same level. That is what a sway bar does...
Now, this is not as ideal as a frame/axle swat bar setup, but it is somewhat functional and definitely cheaper for Dodge, hence why you see them in these cars. Shane By the way that bar inside the rear axle is *NOT* a sway bar. Think about it logically...that bar is inside the axle only and has no attachment to the chassis. It's meant to strengthen the axle only. A real sway bar will attach the suspension to the chassis of the car preventing the chassis from flexing off of the suspension. -----------------------REMOVE-FOOTER-WHEN-REPLYING---------------------------- Questions?
