When the differential is cold, addenough lubricant to raise thelevel from 0 mm (0 in) to 3.2 mm(1/8 in) below the fillplug (A) hole.. When the differential is atoperating temperature (warm),add enough lubricant to raise thelevel to the bottom of the fillplug (A) hole.What to UseRefer to Recommended Fluids andLubricants on page 11-7 todetermine what kind of lubricantto use.Rear AxleWhen to Check LubricantIt is not necessary to regularlycheck rear axle fluid unless there isa leak suspected or an unusualnoise is heard. A fluid loss couldindicate a problem. Have itinspected and repaired.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 takenfive minutes after the vehicle hasbeen driven will appear to have alower fluid level than a vehicle thathas been stationary for an hour ortwo. Remember that the rear axleassembly must be supported to geta true reading.
