Front Axle; Headlamp Aiming - Chevrolet 2010 Colorado Owner's Manual

Front Axle

When to Check and Change Lubricant
It is not necessary to regularly check your 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.
If the level is below the bottom of the filler 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 to 1/2 inch (12 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.
What to Use
See Recommended Fluids and Lubricants on
page 7 10 to determine what kind of lubricant to use.

Headlamp Aiming

Headlamp aim has been preset at the factory and
should need no further adjustment.
However, if your vehicle is damaged in a crash, the
headlamp aim may be affected. Aim adjustment to the
low-beam headlamps may be necessary if oncoming
drivers flash their high-beam headlamps at you (for
vertical aim).
If the headlamps need to be re-aimed, it is
recommended that you take the vehicle to your dealer/
retailer for service.
