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).

CLEANING THE INTERIOR
WARNING:Do not use cleaning solvents, bleach or dye on the
vehicle’s safety belts, as these actions may weaken the belt
webbing.
WARNING:On vehicles equipped with seat-mounted airbags, do
not use chemical solvents or strong detergents. Such products
could contaminate the side airbag system and affect performance of the
side airbag in a collision.
For fabric, carpets, cloth seats, safety belts and seats equipped with side
airbags:
•Remove dust and loose dirt with a vacuum cleaner.
•Apply a layer of high quality foam cleaner, designed for automotive
interiors, to the dry stained area (s) of the item you are cleaning and
allow soaking for one minute.
•If grease or tar is present on the material, spot-clean the area first
with Motorcraft Spot and Stain Remover. In Canada, use Motorcraft
Multi-Purpose Cleaner.
•If a ring forms on the fabric after spot cleaning, clean the entire area
immediately (but do not oversaturate) or the ring can set.
•Do not use household cleaning products or glass cleaners, which can
stain and discolor the fabric and affect the flame retardant abilities of
the seat materials.
CLEANING THE INSTRUMENT PANEL AND INSTRUMENT
CLUSTER LENS
WARNING:Do not use chemical solvents or strong detergents
when cleaning the steering wheel or instrument panel to avoid
contamination of the airbag system.
Clean the instrument panel and cluster lens with a clean, damp, white,
cotton cloth, then use a clean and dry, white, cotton cloth to dry these
areas.
•Avoid cleaners or polishes that increase the gloss of the upper portion
of the instrument panel. The dull finish in this area helps protect the
driver from undesirable windshield reflection.

Checking Tire Pressure
Always check inflation pressure when tires are cold. Never bleed air from
hot tires to relieve normal pressure build-up. Normal increase in pressure
due to service conditions is 10–15 psi (69–103 kPa), which is allowable
in truck tires.
Tires should be properly inflated to manufacturers’ recommended
pressure for the size and service load in which the vehicle is being used.
See the specific tire manufacturer with which your vehicle is equipped
with for the latest information concerning service load and inflation
pressure.
It is particularly important to keep moisture from the inside of tires, and
proper selection of air compressor equipment, proper air line routing,
and the use of shop air dryers is strongly recommended to avoid
moisture in the high pressure air used for tire inflation.
Under-inflation
Do not allow tires to become under-inflated; increased flexing due to
under-inflation causes heat build-up within the tire components. This
leads to reduced strength, breakdown of the rubber compounds, and
possible separation of the tire components (such as ply and tread
separation and reduced retreadability).
Under-inflation is the primary cause of premature tire concerns including
sudden loss of air. In addition, low inflation causes an increase in rolling
resistance. This results in reduced fuel mileage, a loss in tread mileage,
and uneven wear due to increased tread movement. To determine proper
inflation, see the tire manufacturer load and inflation guide, which you
can find on the tire manufacturer website or at your local truck tire
dealer.
Tire Inspection
Check the tires for abnormal wear patterns and proper inflation
pressures. Repair or replace cut or broken tire casings.
Inspect tires for the following conditions. If any are present, remove and
repair, retread, or scrap the tire as the condition dictates.
•Any blister, bump or raised portion anywhere on the surface of the
tire tread or sidewall (other than a bump made by a repair). These
indicate the start of internal separation.
•Any cut that reaches to the belt or ply cords, or any cut that is large
enough to grow in size and depth.
•Any nail or puncturing object.
•If a tread groove is holding a stone or object that is starting to drill
into the tread base, remove the object.

Rotation may not advisable:
•Front (Steering) Axle:Remove tires when tread wears down to
four–thirty seconds inch (3 millimeters) or less. Retread or rotate
worn tires to drive position. We do not recommend using retreaded
tires on steering axles.
•Rear Axles:Remove tires when tread wears down to two–thirty
seconds inch (2 millimeters).
If using a rib tire on front axle and lug or off-road type on rear axle
positions:
•Front (Steering) Axle:Replace tires at front wheels when tread is
worn to four–thirty seconds inch (3 millimeters) or less.
•Rear Axles:Remove tires when the tread wears down to two–thirty
seconds inch (2 millimeters) or less. Tires identified with the word
re-groovable molded on the sidewall can be re-grooved. There must
be a minimum of three–thirty seconds inch (2.5 millimeters) of
under-tread at the bottom of the grooves.
Wheel and Tire Balancing
Out-of-round or out-of-balance wheels or tires can cause vehicle
vibration, bounce and shimmy. Replace damaged or out-of-round wheels.
You can correct out-of-round tires and wheel assemblies by re-clocking
the tire relative to the wheel.
You should then dynamically balance the tire and wheel assembly.
Tire Wear
Radial tires can exhibit three types of normal wear patterns:
•Even
•Erosion
•Chamfer
Even wear:A sign that the tire is being properly used and maintained.
Erosion wear:Also called rolling wear, channel or river wear, erosion
wear occurs more often on free-rolling tires. This is an indication of
using the tire in a slow wearing operation. What happens is that the belt
plies are held very rigid and the tread is not allowed to distort as it
passes through the contact area. Wear only occurs at the edge of the
tread. No corrective action required. If erosion gets to be one–sixteenth
inch (2 millimeters) or more, you can rotate the tire to a drive axle.
Chamfer or shoulder wear:With tires inflated properly, this is a
normal tendency of most radial tire designs. If both inside and outside
shoulders are wearing evenly around the tire, no further action is
required. Over-inflation is not effective in correcting this effect.
