Front Axle
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 PlugA: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 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.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. SeeRecommended Fluids
and Lubricants on page 6-15. 1500 Series

When you end this high-speed driving, return the tires
to the cold ination pressure shown on the Tire and
Loading Information label. SeeLoading the Vehicle on
page 4-34andInflation - Tire Pressure on page 5-76.
Dual Tire Operation
When the vehicle is new, or whenever a wheel,
wheel bolt or wheel nut is replaced, check the
wheel nut torque after 100, 1,000 and 6,000 miles
(160, 1 600 and 10 000 km) of driving. For proper
torque and wheel nut tightening information, see
Removing the Spare Tire and Tools on page 5-95.
The outer tire on a dual wheel setup generally wears
faster than the inner tire. Your tires will wear more
evenly and last longer if you rotate the tires periodically,
seeTire Inspection and Rotation on page 5-84.
Also seeScheduled Maintenance (Gasoline Engine)
on page 6-4.
{CAUTION:
If you operate your vehicle with a tire that is badly
underinated, the tire can overheat. An overheated
tire can lose air suddenly or catch re. You or
others could be injured. Be sure all tires (including
the spare) are properly inated.
SeeInflation - Tire Pressure on page 5-76, for
information on proper tire ination.
5-78

Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle’s tires, including the spare tire, for signs
of wear or damage. SeeWhen It Is Time for
New Tires on page 5-86for more information.
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km). SeeScheduled Maintenance
(Gasoline Engine) on page 6-4.
The purpose of a regular tire rotation is to achieve
a uniform wear for all tires on the vehicle. This will
ensure that your vehicle continues to perform most
like it did when the tires were new.
Any time you notice unusual wear, rotate your tires
as soon as possible and check wheel alignment.
Also check for damaged tires or wheels. SeeWhen
It Is Time for New Tires on page 5-86andWheel
Replacement on page 5-90.
If your vehicle has dual rear wheels, also seeDual
Tire Operation on page 5-78.If your vehicle has single rear wheels and the
tread design for the front tires is the same as the
rear tires, use the rotation pattern shown here
when rotating the tires.
If your vehicle has dual rear wheels and the
tread design for the front tires is the same as the
rear tires, always use one of the correct rotation
patterns shown here when rotating the tires.

Maintenance Schedule
Introduction
This maintenance section applies to vehicles with a
gasoline engine. For diesel engine vehicles, see
the maintenance schedule section in the DURAMAX
Diesel manual.
Important: Keep engine oil at the proper level and
change as recommended.
Have you purchased the GM Protection Plan? The Plan
supplements the vehicle warranties. See the Warranty
and Owner Assistance booklet or your dealer/retailer for
details.
Maintenance Requirements
Notice:Maintenance intervals, checks, inspections,
replacement parts, and recommended uids and
lubricants as prescribed in this manual are
necessary to keep this vehicle in good working
condition. Any damage caused by failure to follow
scheduled maintenance might not be covered by the
vehicle warranty.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep
the vehicle in good working condition, but also helps
the environment. All recommended maintenance
is important. Improper vehicle maintenance can even
affect the quality of the air we breathe. Improper
uid levels or the wrong tire ination can increase the
level of emissions from the vehicle. To help protect
the environment, and to keep the vehicle in good
condition, be sure to maintain the vehicle properly.
6-2

Using the Maintenance Schedule
We want to help keep this vehicle in good working
condition. But we do not know exactly how you will
drive it. You might drive very short distances only a
few times a week. Or you might drive long distances
all the time in very hot, dusty weather. You might use
the vehicle in making deliveries. Or you might drive it to
work, to do errands, or in many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You might need more
frequent checks and replacements. So please read the
following and note how you drive. If you have any
questions on how to keep the vehicle in good condition,
see your dealer/retailer.
This schedule is for vehicles that:
carry passengers and cargo within recommended
limits on the Tire and Loading Information label.
SeeLoading the Vehicle on page 4-34.
are driven on reasonable road surfaces within legal
driving limits.
are driven off-road in the recommended manner.
SeeOff-Road Driving on page 4-13.
use the recommended fuel. SeeGasoline Octane
on page 5-7.The services inScheduled Maintenance (Gasoline
Engine) on page 6-4should be performed when
indicated. SeeAdditional Required Services on page 6-7
andMaintenance Footnotes on page 6-9for further
information.
{CAUTION:
Performing maintenance work on a vehicle can be
dangerous. In trying to do some jobs, you can be
seriously injured. Do your own maintenance work
only if you have the required know-how and the
proper tools and equipment for the job. If you have
any doubt, see your dealer/retailer to have a
qualied technician do the work. SeeDoing Your
Own Service Work on page 5-5.
Some maintenance services can be complex. So, unless
you are technically qualied and have the necessary
equipment, have your dealer/retailer do these jobs.
When you go to your dealer/retailer for service, trained
and supported service technicians will perform the
work using genuine parts.
To purchase service information, seeService
