If you still have the stock front trackbar the axle is slightly shifted to the left due to the lift.
The swaybar will eventually center itself with the axle.
If you install an adjustable trackbar and center the axle, you'll find the swaybar will work itself back to the center.
After all that rambling, I've had 3 lifted Jeeps with the stock trackbar and slightly offset axle and never had a problem arise from it, I say drive it and not worry about it..
