Is it ASD (hydraulically controlled lock up)? If so, I would be very mindful of all the o-rings that are utilized, you wouldn't want to damage one of those during reassembly. Side bearings may be straight forward, however pinion bearings = pre load + depth to ring gear (CRITICAL ADJUSTMENT), then you have ring gear backlash (ALSO CRITICAL).
If the intent is to save money on a replacement differential than it may be wise to seek the assistance of a professional who is equipped with the tools for this particular task!
