I am NOT an expert on this, but one thing I noticed I'm not certain is correct is using the "lifted" version of the JBA upper arms with the OME lift.
I believe the shortness of the left side CRD axle limits lifts to the point that the "lifted" versions are not necessary.
I am sure tommudd will correct this if it's wrong, but it might be something to examine.
I'd be interested to hear what he has to say - JBA is selling the OME lifts as a package with the upper arms, and I specifically bought that package with an eye towards possibly adding another inch or so onto it in the future.
My guess is that caster would be the issue in this case (particularly with the relatively small lift), but that should probably be able to be corrected with shimming at the upper ball joints.
Someone once posted the alignment specs for a lifted liberty. I cant remember exactly what they are. But basically, caster doesn't get adjusted. The lift will cause caster to be a bit out of spec. It just is what it is.
Camber and toe is only what gets adjusted.
All adjustments are done at the lower control arm and tie rod ends. Nothing to adjust with the upper arms.
When I did my lift, I marked the lower cam bolts, then loosened them.
When I had it all back together, I set the cam bolts back to their marked location and tightened them up with the full weight of the jeep on the ground.
All the alignment shop had to do was set the toe.
It pulls a bit to the right but other than that it steers pretty good. Steering is a bit more sensitive because of the increased angle of the tie rods between the rack and steering knuckle.
I will say that the JBA upper arms are necessary for doing the lift.
I thought my lift wouldn't be too much for stock arms, but 8 months later my upper ball joints are showing wear and need replacement.
BTW, if steering still seems too sensitive for you, bigger wider tires will help dampen that feeling
