VEHICLE INSPECTION INFORMATION
To make sure your vehicle is ready to operate, conduct a pre-trip
inspection at the beginning of each work period. Follow the steps listed
in this section to verify a proper vehicle inspection procedure.
WARNING:Exercise great caution when working on a vehicle
equipped with an automatic fan clutch. The fan starts in motion
only after the engine coolant reaches a predetermined temperature or
the refrigerant pressure (if equipped with air conditioning) reaches a
predetermined setting. The fan starts at this point with no advance
warning. Never reach near, or permit objects to protrude into, the fan
blade radius while the engine is running as this could result in vehicle
damage, personal injury or death.
WARNING:Do not operate the vehicle if any suspension
conditions listed in the following charts are evident. Loss of
steering or suspension could result in property damage, personal injury
or death.
WARNING:If a wheel must be changed, obtain expert tire
service help. Mounting and un-mounting of tires should only be
performed by a qualified technician using necessary safety procedures
and equipment, otherwise the result could be property damage,
personal injury or death.
Note:Always make sure you apply the parking brake before starting the
engine.

You can lock and unlock the differential when your vehicle is moving at a
constant speed of less than 25 mph (40 km/h) and while the wheels are
not slipping. Do not lock the differential when your vehicle is traveling
down steep grades and traction is minimal.
The differential lock and differential lock light automatically disengage at
speeds above 25 mph (40 km/h). The differential lock remains off until
either you restart your vehicle or you turn the differential lock switch off
then back on.
Turn the engine off and raise all drive wheels of the locker differential
axle in order to prevent your vehicle from moving when servicing the
wheels, tires or brakes. Axles equipped with a NoSPIN Detroit Locker
differential deliver power to both wheels even when only one wheel is on
the ground.
WARNING:Failure to raise all drive wheels with this type of
differential could cause the vehicle to move unexpectedly,
resulting in property damage, personal injury or death.
Take care to avoid sudden accelerations when both drive wheels are on a
slippery surface.
WARNING:Sudden accelerations on slippery surfaces could
cause the wheels to spin, the vehicle to turn sideways on a
crowned road surface or in a turn, possibly resulting in loss of vehicle
control and personal injury.
Fluid Temperature
Axle operating temperatures normally do not exceed 100°F (38°C). If
the operating temperature exceeds 230°F (110°C), the rate of axle
lubrication oxidation increases and shortens the life of the lubricant and
seals, requiring axle lubrication changes to become more frequent to
preserve the axle. Do not consistently run extreme pressure (EP)
lubricants above 230°F (110°C).
Axle Conversions
WARNING:When operating a loaded vehicle, the driver must
keep all adjustable axles on the ground at all times, supporting
their share of the vehicle’s load. Failure to do so can overload other
axles, tires, wheels, springs, steering components, brakes and frames,
resulting in early component failure, loss of vehicle control, possible
property damage and personal injury.

If the steering wanders or pulls, check for:
•Underinflated tire(s) on any wheel(s)
•Uneven vehicle loading
•High crown in center of road
•High crosswinds
•Wheels out of alignment
•Loose or worn suspension components.
AIR SUSPENSION (IF EQUIPPED)
Note:Do not operate your vehicle without air in the suspension springs.
Operating your vehicle without air in the suspension springs damages the
suspension, degrades ride performance and may cause property damage.
The air suspension system automatically adjusts to different loads to
maintain a constant frame height, allows for ease of vehicle loading,
provides improved vehicle ride, and increased driver comfort.
Air Suspension Dump Switch
Note:The suspension dumps air when the ignition is in the accessory or
on position, but fills only when the ignition is in the on position.
A switch located in the overhead
switch pack controls the system. It
operates only when the ignition is in
the accessory or on position and the
air tanks have sufficient pressure to
fill the air springs. When you turn
off the ignition, the suspension
remains in whatever state it was last
set.
Pressing the lower portion of the switch exhausts air from the air
springs, lowering the frame for loading. Pressing the upper portion of the
switch fills the air springs so your vehicle remains at normal ride height.
System Indicator Light
The air suspension indicator light illuminates when using the
switch to release air pressure in the rear air shocks. Never
drive your vehicle when the warning lamp is illuminated and
there is low (or no) air pressure in the shocks.

Climate Control System
Have the air conditioning system checked each spring. The refrigerant
charge, cleanliness of the condenser-evaporator cores and belt condition
are essential to system performance.
When the air conditioning system is being used daily, remove the fresh
air filter (if equipped) once each season and check for things such as
dirt and lint. Replace the filter if necessary. Vehicles operating in
unusually dusty conditions may require more frequent filter inspection
and replacement.
Front Axle
Maintaining the front axle alignment to specifications is very important.
A qualified technician should check and maintain the alignment. Regular
inspections should include:
•Toe-in inspection and adjustment (if necessary), particularly with
radial tires.
•Checking for proper tightness of axle mounting U-bolt nuts, attaching
or mounting bolts and nuts.
•Checking the axle for damage, binding, worn parts and adequate
lubrication..
•Checking the kingpins for excessive wear. Also, perform this check
during other scheduled maintenance (such as tire rotation or service,
wheel bearing service and alignment). See the workshop manual for
proper procedures.
Toe-in
It is essential to maintain correct toe-in and tire pressure for optimum
tire wear.
Inspecting steer axle tires in the first 3000–10000 service miles
(5000–16000 service kilometers) generally shows if tires are wearing
normally.
Rapid outside shoulder wear on both tires indicates too much toe-in.
Rapid inside shoulder wear on both tires indicates too much toe-out.
In P&D-type service, there can be a left-to-right steer tire tread life
differential up to 40% depending on routes and other variables.
Follow the tire manufacturer’s recommended cold inflation pressure for
the tire size, load range (ply rating) and steer axle loading typical for
their operation (each steer axle tire equals
12steer axle loading).

TIRES
Tire Inflation Information
WARNING:Always maintain your tires in good condition.
Frequently check and maintain correct inflation pressures as
specified by tire manufacturers. Inspect periodically for abnormal wear
patterns and repair/replace cut or broken tire casings. Always use
experienced, trained personnel with proper equipment and correct
procedures to mount or remove tires and wheels. Failure to adhere to
these warnings could result in wheel or tire malfunction, damage to
your vehicle, personal injury, or death.
WARNING:To avoid personal injury or death, always follow
these instructions when mounting radial tires on wheels:
•Only personnel that have had proper training and experience should
mount or remove tires from rims or wheels.
•Use only heavy-duty rims or approved rims for radial tires. It may be
necessary to contact your wheel and rim distributor to determine if
you can use radial tires with your rims.
•If you are using a tube, make sure to use special radial tire tubes
because of the increased flexing of the sidewalls on radial tires.
•Never use anti-freeze, silicones, or petroleum-based lubricants when
mounting radial tires. Make sure to use only an approved lubricant as
an aid for mounting tires.
•Always inflate tires in a safety cage.
•Do not attempt to mix stud piloted wheels or fasteners with hub
piloted wheels or fasteners. To do so may cause premature wheel
failure resulting in property damage, personal injury, or death.
•Do not mix foreign (not made in North America) wheel-mounting
parts with domestic (made in North America) parts. Many foreign
wheel components look similar to, but are not the same as domestic
made components. Mixing components could cause wheel or fastener
failures and result in property damage, personal injury, or death.
