The correct procedure when gear lube starts to flow out upon removing the inspection/fill plug is to quickly replace the plug to prevent any more loss of gear lube. This indicates that the differential has enough fluid. Allowing the fluid to continue to drain is unnecessary and could lead to insufficient lubrication.
