the code plate. Refer to the decoding chart to decode lines 1
through 3.
Lines 4 through 7 on the plate are imprinted in se­
quence according to the following descriptions:
• 3-character sales code • 3-digit numerical code
• 6-digit SEC code If there is not enough space left in the row for all
of the 6-digit SEC code:
• The unused space will remain blank
• The code will be listed in the next row.
The last nine positions of row 7 will contain a
2-digit code and a 6-digit serial number.
The last code on a vehicle code plate will be fol­
lowed by the imprinted word END. When two plates
are required, the last available spaces on the first
plate will be imprinted with the letters CTD (for con­ tinued).
When a second vehicle code plate is necessary, the
first four spaces on each row will not be used because of the plate overlap.
To retrieve information from a vehicle code plate:
• Illuminate the plate with a shop light
• View the plate via the cowl grille slots
• Record the needed coded information.

INTRODUCTION
Lubrication and maintenance is divided into re­
quired and recommended service tasks. The required service tasks must be completed to verify the emis­
sion controls function correctly. The recommended
service tasks should be completed to maintain safety
and durability. This information will assist the service personnel
in providing maximum protection for each owner's
vehicle. Conditions can vary with individual driving habits.
It is necessary to schedule maintenance as a time in­
terval as well as a distance interval. It is the owner's responsibility to determine the ap­
plicable driving condition. Also to have the vehicle serviced according to the maintenance schedule, and
to pay for the necessary parts and labor. Vehicles with a Gross Vehicle Weight Rating
(GVWR) of 3 855 kg (8,500 lbs.) or less must conform
to light duty emission standards. Vehicles with a Gross Vehicle Weight Rating (GVWR) of 3 856 kg
(8,501 lbs.) or more must conform to heavy duty
emission standards. The GVWR for each vehicle is listed on the Safety
Certification Label. This label is affixed to the driver
side door pillar (Fig. 1).
Additional maintenance and lubrication informa­
tion is listed in the Owner's Manual.

should decrease the interval between component
maintenance. Severe driving conditions are defined
as:

• Frequent short trip driving less than 24 km (15
miles)
• Frequent driving in dusty conditions
• Trailer towing
• Extensive engine idling
• Sustained high speed operation
• Desert operation
• Frequent starting and stopping
• Cold climate operation

LUBRICATION
AND
MAINTENANCE

• Commercial service
When a vehicle is continuously subjected to severe
driving conditions, lubricate:
• Body components
• All the driveline coupling joints
• Steering linkage More often than normal driving conditions

DUSTY
AREAS
With this type of severe driving condition, special
care should be given to the:
• Engine air cleaner filter
• PCV filter
• Crankcase ventilation system
• Brake booster control valve air filter. Verify that the filters and the associated compo­
nents are clean. Also verify that they are functioning
effectively. This will minimize the amount of abra­ sive particles that enter the engine.

OFF-ROAD
(4WD)
OPERATION
After off-road (4WD) operation, inspect the under­
side of the vehicle. Inspect the:
• Tires
• Body structure
• Steering components
• Suspension components • Exhaust system
• Threaded fasteners

HARSH
SURFACE ENVIRONMENTS
After extended operation in harsh environments,
the brake drums, brake linings, and rear wheel bear­ ings should be inspected and cleaned. This will pre­
vent wear and erratic brake action.

ROUTINE MAINTENANCE
The following routine maintenance is recommended
on a monthly basis: TIRES—Inspect the tires for unusual wear/damage.
Determine if the inflation pressure is adequate for
the vehicle load. BATTERY—Inspect and clean the terminals.
Tighten the terminals if necessary. FLUIDS—Determine if the component fluid levels
are acceptable. Add fluid, if necessary. LIGHTS/ELECTRICAL—Test all the electrical sys­
tems in the vehicle for proper operation. It is also recommended that the engine oil and the
washer fluid level be determined at each fuel fill-up.

BODY
COMPONENT
MECHANISMS
LUBRICATION REQUIREMENTS
All operating mechanisms and linkages should be
lubricated when necessary. This will maintain ease of operation and provide protection against rust and
excessive wear. The door weatherstrip seals should
be lubricated to prolong their life as well as to im­ prove door sealing.

LUBRICANT SPECIFICATIONS
All applicable exterior and interior vehicle operat­
ing mechanisms should be:
• Inspected • Cleaned
• All the pivoting/sliding contact areas on the mech­ anisms should then be lubricated.
MOPAR®Multi-Mileage Lubricant or an equiva­
lent, should be used to lubricate the mechanisms.
The door weatherstrip seals should be lubricated
with silicone lubricant spray. Refer to the Body Lu­
bricant Specifications chart below for additional lu­
bricant applications.

LUBRICATION
(1) When necessary, lubricate the cab and cargo
box operating mechanisms with the specified lubri­
cants.

(2) Apply silicone lubricant to a cloth and wipe it
on door seals to avoid over-spray that can soil pas­
senger clothing. (3) Before applying lubricant, the component
should be wiped clean. After lubrication, any excess
lubricant should be removed.
(4) The hood latch, latch release mechanism, latch
striker and safety latch should be lubricated periodi­
cally.
(5) The door lock cylinders should be lubricated 2
times each year (preferably autumn and spring): • Spray a small amount of lock cylinder lubricant di­
rectly into the lock cylinder
• Apply a small amount to the key and insert it into
the lock cylinder • Rotate it to the locked position and then back to
the unlocked position several times
• Remove the key. Wipe the lubricant from it with a
clean cloth to avoid soiling of clothing.

TIRES
RECOMMENDED MAINTENANCE
The condition of the tires should be inspected. The
inflation pressures tested/corrected at the same time as the engine oil is changed and the oil filter is re­
placed.
The tires/wheels should be rotated periodically to
ensure even tread wear. The tires/wheels should be
rotated at the first 12 000 km (7,500-miles) interval.
Thereafter, at each 24 000 km (15,000-miles) inter­
val.
INSPECTION
Inspect the tires for excessive wear, damage. Test
the tires for the recommended inflation pressure and adjust the pressure accordingly. Refer to the tire in­
flation pressure decal located on the left door face. Also to Group 22—Tires And Wheels for tire pres­sure charts, tire replacement, and treadwear indica­

tors.

ROTATION
Tires/wheels should be rotated according to the rec­
ommended interval. The first tire/wheel rotation is
the most important for establishing the prevention of uneven tread wear. After rotation, adjust the tire in­
flation pressure to the air pressure recommended on
the decal located on the left door face.
Refer to Group 22—Tires And Wheels for the rec­
ommended method of tire/wheel rotation.

FRONT
WHEEL
ALIGNMENT

GENERAL
INFORMATION
Front wheel alignment involves
the
correct posi­
tioning
of the
tire contact patch
in
relation
to the

pavement.
The
positioning
is
accomplished through
the suspension
and
steering linkage adjustments.
An
alignment
is
essential
for
efficient steering
and
direc­
tional stability.
The
most important factors
of
front
end alignment
are
camber, caster
and toe
position. Routine inspection
of
the front
suspension
and
steering components
is a
good
preventative

maintenance practice.
Inspection
also
helps
to
ensure
safe operation
of the
vehicle.

• CAMBER
is the
number
of
degrees
the top of the

wheel
is
tilted either inward
or
outward.
An
excessive
negative camber angle will cause tread wear
at the in­
side
of
the tire.
An
excessive positive camber angle will
cause tread wear
at the
outside
of
the tire (Fig.
1),
• CASTER
is the
number
of
degrees
of
forward
or

rearward tilt
of the
steering knuckles. Forward tilt
provides
a
negative caster angle. Rearward tilt pro­ vides
a
positive caster angle
(Fig. 1).

• WHEEL
TOE
POSITION
is the
difference between
the leading
and
trailing inside edges
of the
front
tires (Fig.
1).
Incorrect wheel
toe
position
is the
most common cause
of
unstable steering
and
steering wheel off-center.
The
wheel
toe
position
is the
final
front wheel alignment adjustment. • STEERING AXIS INCLINATION ANGLE
is
mea­
sured
in
degrees
and is the
angle that
the
steering
knuckles
are
tilted (Fig. 1).
The
inclination angle
has

a fixed relationship with
the
camber angle. This will
not change except when
a
spindle
or
ball stud
is

damaged
or
bent.
The
angle
is not
adjustable
and the

damaged component(s) must
be
replaced
to
correct
mis-alignment.

CAUTION:
Do not
attempt to modify
any
suspension

or steering
component
by
heating
and
bending.

PRE-ALIGNMENT INSPECTION
Before starting
a
front wheel alignment,
the
follow­
ing inspection
and
necessary corrections must
be
completed.
(1)
Tires with
the
same recommended
air
pressure,

size,
and
tread wear. Refer
to
Group
22,
Wheels
and

Tires
for
diagnosis information. (2) Front wheel bearings
for
wear
or
adjustment.
(3) Ball studs
and
linkage pivot points, steering
gear
for
looseness, roughness, binding
or a
sticking
condition. Refer
to
Group
19,
Steering
for
additional information.

WHEEL
ALIGNMENT
MEASUREMENTS/ADJUSTMENTS
The front wheel alignment positions must be set to
the specified limits. This will prevent abnormal tire
tread wear. The equipment manufacturer's recommenda­
tions for use of their
equipment
should always
be followed. All
damaged
front suspension sys­
tem components
should
be replaced. Do not at­ tempt to straighten any
bent
component.

CAMBER AND CASTER-2WD VEHICLES Camber and caster angle adjustments involve repo­
sitioning the upper suspension arm cam adjustment
bolts (Fig. 2). Alignment adjustments are accom­
plished by loosening the nuts and changing the posi­
tion of the cam bolt.
(1) Remove all foreign material from the adjust­
ment bolt threads.
(2) Record the camber and caster measurements
before loosening the adjustment bolt nuts.
(3) The camber angle should be adjusted as near as
possible to the preferred angle. The caster should be
the same at both sides of the vehicle. Refer to the Specifications chart.
CAMBER AND CASTER—4WD VEHICLES For 4WD vehicles, the correct wheel camber (verti­
cal tilt) angle is factory preset at zero degree (0°).
Camber cannot be altered by adjustment.
CAUTION: Do not attempt to
adjust
the
camber
an­
gle by
heating
or bending the axle or any
suspen­

sion
component. If camber angle is
incorrect,
the
component(s)
causing
an
incorrect
angle must be replaced.
(1) It is important that the camber (vertical tilt)
angle be the same for both front wheels.
(2) The camber angle should be measured with ac­
curate wheel alignment equipment. The acceptable
range is -1° to +1°. Refer to the Specifications chart.
Road test the vehicle and observe the steering
wheel return-to-center position. Before road testing,
check
and
correct
the tire
inflation pressures. Inflate
both
of the front tires
with exactly the
same
pressure.
During the road test, make vehicle turns to both
the left and right. If the steering wheel returns to­
ward the center position unassisted, the caster angle is correct. However, if the steering wheel does not re­ turn toward the center position unassisted, an incor­
rect caster angle is probable.
(1) The caster angle is factory preset at positive
two degrees
(
+
2°).
The acceptable range is +1/2° to +
3
1/2°.
(2) The caster angle should be measured with ac­
curate wheel alignment equipment.
(3) Caster angle can be adjusted by installing ta­
pered shims between the front axle pads and the spring brackets. The caster angle should be adjusted
as near as possible to the preferred angle.
(4) Record the caster measurement before remov­
ing the original shims from the spring pads.
(5) The caster should be the same at both sides of
the vehicle. Refer to the Specifications chart.

WHEEL TOE POSITION The wheel toe position adjustment should be the fi­
nal front wheel alignment adjustment. In all in­ stances, follow the equipment manufacturer's
recommended procedure.
(1) Secure the steering wheel with the front wheels
in the straight-ahead position. For vehicles equipped
with power steering, start the engine before straight­ ening the wheels.
With power steering, the engine should be op­
erating during the wheel toe position adjust­
ment.
(2) Loosen the tie rod adjustment sleeve clamp
bolts (Fig. 3).
(3) Adjust the wheel toe position by rotating the
tie rod adjustment sleeve (Fig. 3). Rotate each tie-rod end in the direction of
sleeve rotation during the adjustment (Fig. 3).
This will ensure that both tie-rod ends are at the center of their travel.
(4) If applicable, turn the ignition switch off.
