When to Check and Change Lubricant
It is not necessary to regularly check front axle
uid unless you suspect there is a leak or you hear
an unusual noise. A uid 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.A:Fill Plug
B:Drain Plug
If the level is below the bottom of the ller plug hole,
located on the front axle, you may need to add
some lubricant:
When the differential is cold, add enough
lubricant to raise the level from 0 (0 mm) to
1/8 inch (3.2 mm) below the ller plug hole.
When the differential is at operating
temperature (warm), add enough lubricant
to raise the level to the bottom of the ller
plug hole.
