10-32 Vehicle Care
Also, if a vehicle has just been
driven before checking the fluid
level, it may appear lower than
normal because fluid has traveled
out along the axle tubes and has
not drained back to the sump
area. Therefore, a reading taken
five minutes after the vehicle has
been driven will appear to have a
lower fluid level than a vehicle that
has been stationary for an hour or
two. Remember that the rear axle
assembly must be supported to get
a true reading. How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.
The proper level is from 1.0 mm to
19.0 mm (0.04 in to 0.75 in) below
the bottom of the filler plug hole,
located on the rear axle. Add only
enough fluid to reach the proper
level.
What to Use
Refer to Recommended Fluids and
Lubricants on page 11‑12 to
determine what kind of lubricant
to use.
