Speaking from the JK side
It doesn't matter what model jeep you have, every one is mfd to specs and every one is a LITTLE different
Your 2" lift caused the axles to shift ever so slightly to left/right, but the axles may have been off ever so slightly to start with !!
Two things show up, your pinion angle (universals) will change a little and your axle placement in relation to the body will change--may not look good from behind--relative
After my 2.5" lift myJKU is steady, caster is OK, no vibrations--each jeep is a little diff. !!
Don't forget to check your swaybars for proximity to tires and levelness--may need new links !!
