knock the roll pin out on driveshaft and pull the shaft off the output of diff. unplug diff and take 4 bolts out of the frame. i am guessing you know how to pull front axles? if not just jack up the front and undo lower ball joint and pull them out, sound like a roll pin problem or armature plate. i would go wicked weasel and 1/8" roll pin. $100 upgrade if you do it yourself. the diff isn't complicated. pm me and i will send you my number to walk you through it
