How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.
If the level is below the bottom of
the fill plug hole, some lubricant
may need to be added.
When the differential is cold, add
enough lubricant to raise the level to
10 mm (3/8 in) below the fill
plug hole.
When the differential is at operating
temperature (warm), add enough
lubricant to raise the level to the
bottom of the fill plug hole.
