All axle assemblies are filled byvolume of fluid during production.They are not filled to reach a certainlevel. When checking the fluid levelon any axle, variations in thereadings can be caused by factoryfill differences between the minimumand the maximum fluid volume.Also, if a vehicle has just beendriven before checking the fluidlevel, it may appear lower thannormal because fluid has traveledout along the axle tubes and hasnot drained back to the sump area.Therefore, a reading taken
