First off I need to apologize to Steve. The method I asked you to use for measuring was flawed. My reasoning was wrong. Sorry.
I realized the error in my thinking once I started the process. There was going to be little difference when measuring the wheel articulation. Sure there would be small differences, but hardly enough to measure and requiring much too much equipment to effectively raise the vehicle high enough. I raised one tire 16" off the ground and still was not getting the other tire to lift. This was before removal, so you can imagine the mess trying to lift the one side with the bar removed. Scary
I really should not have put anyone else in that situation. Thank goodness no one was stupid enough to try it and get hurt.
I kind of set you up for a fall unintentionally.
What needed to be measured is the body roll. Articulation is controlled by the sway bar. The speed at which the sway bar reacts is controlled by the links.
To some extent the sway bar bushings do affect the body roll in that they crush and allow "slop" in the sway bars transfer to the control arms.
Prompted by the quest to disconnect the sway bar I installed the polyurethane bushing kit. The parts look good. It is a shame to spend $30 for no more than you get, but there are not many options here. One bushing showed signs of porosity, but it appears to be a surface defect only. The rest all looked good.
The install went well. No surprises.
I tested the truck in a ramp. This was far from scientific conditions. I could bore you all with all the measurements, but I'll just cut to the chase.
The replacing the stock rubber bushings with the polyurethane bushings reduced the body roll 15%.
