Default Front Upper Adjustable Control Arms

So I think I have some issues with my caster. Just installed a new lift and it's got a flighty feeling. The kit came with adjustable front upper arms, only. If I wanted to adjust these arms do I need to use a jack and jack stands to take the weight off the tires or can I just adjust one arm at a time with the Jeep on the ground?

I've done lowers on the ground-one at a time. It took some effort to move the axle into place--I used a ratcheting cargo tiedown (a real one, not one of those tiny things sold at Walmart) to hold the axle, then pull it into place. Whatever you do, just be sure that you torque the control arm hardware after the vehicle is fully on its own weight. Good idea to leave hardware a bit loose until on all four wheels, bounce around to remove any control arm preload, then torque to spec (85 ft-lbs on the front uppers, IIRC). You should also loosen the lowers, then retorque at the same time (125 ft-lbs).

Thanks, Mark.

Wonder if the torque could be the issue, I torqued most of the front down when it was up in the air. I'm going to re-measure my caster and then check torque before I start messing with the arm lengths.

Thanks,

Steve
