Front Axle - Cadillac 2005 STS Owner's Manual

Front Axle

When to Check and Change Lubricant
It is not necessary to regularly check the 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
A. Drain Plug
B. Filler Plug
5-46
To get an accurate reading, the vehicle should be on a
level surface.
If the level is below the bottom of the filler plug hole,
located on the front axle, you may need to add
some lubricant.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. See Recommended Fluids
and Lubricants on page 6-12.
