    Hoping someone here has some incite

    My new ram has a 4 link and panhard bar from
    Factory. I added new link bars that you can adjust, and rear air bags to replace coils

    Naturally as its lowered the axle has shifted to the passenger side. Hence why I also purchased an adjustable panhard bar. But when I go to adjust the rear axle over it starts to lower the driver side and raise the passenger side. Even if I completely air out the rear bags it still sits lower on the driver side.

    Any incite to what's causing this?

    something is keeping the rear end from shifting over did you try adjusting it and cycling the suspension?

    It'll shift over fine, but at the same time raise and lower.

    Yah I bounced it, drove it etc

    I'd pull the panhard and see what happens

    Main question, Individual bag control or bags tee'd together?

    are all the lowers adjusted to the same length and the uppers adjusted to the same length? if they are different lengths, it can cause the axle to rotate unevenly causing the twist in the axle.

    The panhard bar mounting point on the frame will also cause a pivot effect. it is not pushing directly to the center of the frame cross section to center your axle. it pushing on that pivot point which is located XX" off the center.
    the frame is going to pivot at it's CG. so if you're applying the force in a plane that is not on the x or y origin planes from the CG, you will get lean from one side to the other.

    this is fine, as long as you DO NOT DRIVE IT, just cycle the suspension.
