When to Check Lubricant
It is not necessary to regularly check rear axle fluid unless you suspect there is a leak or you hear an unusual noise. A fluid loss could indicate a problem. Have it inspected and repaired.
How to Check Lubricant

To get an accurate reading, the vehicle should be on a level surface.
The proper level is from 0 to 3/8 inch (0 to 10 mm) below the bottom of the filler plug hole, located on the rear axle.
