you'll need to remove the wheels to unbolt the spindles and calipers, and then pull the axles out of the differential....the diff can then be removed and the spindles bolted back up. You can then put the wheels on. I think the axles will hang down on the ground though. I imagine if you support the axles somehow, you should be able to do it and move the car around. you also may want to support the driveshaft so it doesn't fall out the end of the driveshaft.
