wheel dragging or the vehicle pulling to one side.
(3) Evaluate any performance complaints received
from the owner/operator. (4) Repair the brake system as necessary (refer to
Group 5—Brakes for additional information and ser­
vice procedures).

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.

proper procedures.
The
preferred headlamp alignment setting
is 0 for

the left/right adjustment
and
1" down
for the up/
down adjustment.

HEADLAMP
ALIGNMENT PREPARATION
(1) Verify headlamp dimmer switch
and
high beam
indicator operation. (2) Correct defective components that could hinder
proper headlamp alignment. (3) Verify proper tire inflation. (4) Clean headlamp lenses.
(5) Verify that luggage area
is not
heavily loaded.

• (3) Up 1.27 meters (5 feet) from the floor, tape a
line on the wall at the centerline of the vehicle.
Sight along the centerline of the vehicle (from rear of
vehicle forward) to verify accuracy of the line place­
ment.
(4) Rock vehicle side-to-side three times to allow
suspension to stabilize. (5) Jounce front suspension three times by pushing
downward on front bumper and releasing. (6) Measure the distance from the center of head­
lamp lens to the floor. Transfer measurement to the alignment screen (with tape). Use this line for up/
down adjustment reference.
(7) Measure distance from the centerline of the ve­
hicle to the center of each headlamp being aligned. Transfer measurements to screen (with tape) to each side of vehicle centerline. Use these lines for left/
right adjustment reference.

HEADLAMP
ADJUSTMENT
A properly aimed low beam headlamp will project
top edge of high intensity pattern on screen from 50 mm (2 in.) above to 50 mm (2 in.) below headlamp
centerline. The side-to-side outboard edge of high in­
tensity pattern should be from 50 mm (2 in.) left to 50 mm (2 in.) right of headlamp centerline (Fig. 1).
The preferred headlamp alignment is 0 for the
up/down adjustment and 1" down for the left/
right adjustment. The high beam pattern should be correct when the iow beams are aligned properly (Fig. 2).
To adjust headlamp aim, rotate alignment screws
to achieve the specified high intensity pattern.
