steering DODGE CARAVAN 2004 4.G Owner's Manual

All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason, the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:Increased noise levels at the end of the steering
wheel travel are considered normal and does not indicate
that there is a problem with the power steering system.
WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolong operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and should be avoided when
possible. Damage to the power steering pump may
occur.
240 STARTING AND OPERATING

WARNING!
Overloading of your tire is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle-never
overload them.
TIRESÐGENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:1. SafetyÐ
WARNING!
Improperly inflated tires are dangerous and can cause
accidents.
²Under inflation increases tire flexing and can result in
tire failure.
²Over inflation reduces a tire's ability to cushion
shock. Objects on the road and chuck holes can cause
damage that results in tire failure.
²Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
²Over inflated or under inflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of
vehicle control.
²Unequal tire pressures from one side of the vehicle to
the other can cause the vehicle to drift to the right or
left.
Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.

WARNING!
²Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspen-
sion dimensions and performance characteristics,
resulting in changes to steering, handling, and brak-
ing of your vehicle. This can cause unpredictable
handling and stress to steering and suspension com-
ponents. You could lose control and have an accident
resulting in serious injury or death. Use only the tire
and wheel sizes with load ratings approved for your
vehicle.
²Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have an accident.
²Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Alignment And Balance
Poor suspension alignment may result in:
²fast tire wear;
²uneven tire wear, such as feathering and one-sided
wear;
²vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.
258 STARTING AND OPERATING

Snow tires generally have lower speed ratings than what
was originally equipped with your vehicle and should
not be operated at sustained speeds over 75 mph (120
km/h).
TIRE ROTATION RECOMMENDATIONS
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, driving,
and braking functions. For these reasons, they wear at
unequal rates, and tend to develop irregular wear pat-
terns.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on all season type
tires. Rotation will increase tread life, help to maintain
mud, snow, and wet traction levels, and contribute to a
smooth, quiet ride.
Follow the recommended tire rotation frequency for your
type of driving found in the ªMaintenance SchedulesºSection of this manual. More frequent rotation is permis-
sible if desired. The reasons for any rapid or unusual
wear should be corrected prior to rotation being per-
formed.
NOTE:The Tire Pressure Monitor system must be
retrained following a tire rotation. See your authorized
dealer for service.
The suggested rotation method is the ªforward-crossº
shown in the following diagram.

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between Reverse
and Drive. Usually the least accelerator pedal pressure to
maintain the rocking motion without spinning the
wheels is most effective.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure
someone. Do not spin your vehicle's wheels faster
than 35 mph (55 km/h) when you are stuck. And
don't let anyone near a spinning wheel, no matter
what the speed.
CAUTION!
Racing the engine or spinning the wheels too fast
may lead to transmission overheating and failure. It
can also damage the tires. Do not spin the wheels
above 35 mph (55 km/h).
TOWING A DISABLED VEHICLE
With Ignition Key
Front Wheel Drive
Your vehicle may be towed under the following condi-
tions: The gear selector must be in NEUTRAL, the
distance to be traveled must not exceed 100 miles (160
km), and the towing speed must not exceed 44 mph (72

6

km/h). Exceeding these towing limits may cause a trans-
mission geartrain failure. If the transmission is not op-
erative, or if the vehicle is to be towed more than 100
miles (160 km), the vehicle must be towed with the front
wheels off the ground.
All Wheel Drive
Your vehicle may be towed under the following condi-
tions: The gear selector must be in NEUTRAL, the
distance to be traveled must not exceed 100 miles (160
km), the towing speed must not exceed 44 mph (72
km/h), and both front and rear wheels must be on the
ground. If your vehicle must be towed farther or at a
higher rate of speed, it must be transported on a flat bed
truck.
All Transmissions
CAUTION!
²Do not attempt to tow this vehicle from the front
with sling type towing equipment. Damage to the
front fascia will result.
²Always use wheel lift equipment when towing
from the front. The only other approved method
of towing is with a flat bed truck.
²Do not tow the vehicle from the rear. Damage to
the rear sheet metal, liftgate and fascia will occur.
²Do not push or tow this vehicle with another
vehicle as damage to the bumper fascia and trans-
mission may result.
²If the vehicle being towed requires steering, the
ignition switch must be in the OFF position, not
in the LOCK or ACCESSORY positions.

296 MAINTAINING YOUR VEHICLE

Power Steering Ð Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through a certified
DaimlerChrysler Dealership.9
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to insure accurate fluid level reading. Do
not overfill. Use only manufacturers recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to Recommended Fluids, Lubricants, and
Genuine Parts for correct fluid type.
Front Suspension Ball Joints
The front suspension ball joints are permanently sealed.
No regular maintenance is required for these compo-
nents.
Steering Shaft Seal
The steering shaft seal, at the point where the shaft passes
through the bulkhead, is lubricated when it is installed. If
the seal becomes noisy when the steering shaft is turned,
it should be lubricated. Use only manufacturers recom-
mended lubricant, refer to Recommended Fluids, Lubri-
cants and Genuine Parts for correct lubricant type.
314 MAINTAINING YOUR VEHICLE

Steering Linkage
The tie rod end ball joints are permanently lubricated and
do not require periodic maintenance.
Drive Shaft Universal Joints
Your vehicle has constant velocity universal joints. Peri-
odic lubrication of these joints is not required. However,
the joint boots should be inspected for external leakage or
damage when other maintenance is performed. If leakage
or damage is evident, the universal joint boot and grease
should be replaced immediately.
Continued operation could result in failure of the univer-
sal joint due to water and dirt contamination of the
grease. This would require complete replacement of the
joint assembly.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, doors, liftgate, sliding doors and hood hinges,
should be lubricated periodically to assure quiet, easy
operation and to protect against rust and wear. Prior to
the application of any lubricant, the parts concerned
should be wiped clean to remove dust and grit; after
lubricating excess oil and grease should be removed.
Particular attention should also be given to hood latching
components to insure proper function. When performing
other underhood services, the hood latch, release mecha-
nism and safety catch should be cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the fall and spring. Apply a small
amount of a high quality lubricant such as MopartLock
Cylinder Lubricant directly into the lock cylinder.
