i had vibration when accelerating in the begining of first gear with just a 2.5" shackle lift and stock 30's. usually doing anything (besides a body lift) to fit 33's is going to require a slip yoke eliminator and an upgraded cv driveshaft. these can be somewhat expensive but worth the investment, this will help cut down on wear and tear on both your tranny and diff and will alloy you to flex to your full capability. as for dropping the t case, usually this is done when working towords 38's, and after the sye and cv upgrades have already been installed
