Front Axle
When to Check and Change Lubricant
It is not necessary to regularly check front 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.
A: Fill Plug
B: Drain Plug
• 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 filler plug hole.
• When the differential is at operating temperature
(warm), add enough lubricant to raise the level to the
bottom of the filler plug hole.
