No, you should not drive a vehicle with no oil in the differential. The differential relies on oil for lubrication to reduce friction and prevent overheating of its components. Operating without oil can lead to severe damage, including gear wear and failure, which may result in costly repairs and unsafe driving conditions. Always ensure that the differential is properly lubricated before driving.

If by "rear gear" you mean the differential, that joins the driveshaft to the rear axle: If run without sufficient oil it will overheat and eventually be ruined. Ordinarily the rear differential oil seldom needs changing, as unlike engine oil it does not have combustion byproducts constantly contaminating it. If however you drive through floodwaters, water can enter through the vent, which will ruin the differential oil. If you run through flooded water you should have the differential oil changed.
