My opinion,...
the best way to install a sway bar is with the truck resting on it's wheels.
I use to use a set of metal vehicle ramps to get the truck up in the air, but now I use my stands made from old 2x4"s.
I also loosely attach the bar to the a-arms first,... then use a floor jack to lift the center of the bar to attach the frame mounts.
Some times you have to use longer than normal bolts to pull the bushings and u-straps up tight.
Then I replace them one-by-one with the correct length bolts.
Make a set of these stands.
They work great.
