In my experience with lifting jeeps. Whenever you get alignment issues with accelerating/decelerating the culprit is usually rear control arm bushings. Think about it. When you accelerate, your increasing torsion on the rear axle. and its going to want to twist if the bushings are shot. Since You lifted the truck, I doubt you loosened the rear or front control arm bolts priot to lift kit install and then to re-torque them at your new ride height, right?
ALWAYS whenever you install new control arms front or rear or a lift kit, you ONLY torque to spec the control arm bolt when you're at ride height. Otherwise if torquing them on a lift, you will destroy the bushings quickly since the bushings will twist when you lower the truck back down and then the constant up twisting of daily driving, your rubber bushings will be shredded.
