2007 CHRYSLER PACIFICA suspension

WARNING!
•Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of un-
approved tires and wheels may change suspension
dimensions and performance characteristics, resulting
in changes to steering, handling, and braking of your
vehicle. This can cause unpredictable handling and
stress to steering and suspension components. 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.
•Never 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.
•Failure to equip your vehicle with tires having ad-
equate 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:
•Fast tire wear.
•Uneven tire wear, such as feathering and one-sided
wear.
•Vehicle 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.
STARTING AND OPERATING 305

Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
TIRE CHAINS
Use only compact chains, or other traction aids that meet
SAE type “Class S” specifications. Chains must be the
proper size for the vehicle, as recommended by the chain
manufacturer.
NOTE:Do not use tire chains on a compact spare tire.
CAUTION!
To avoid damage to your vehicle or tires, observe the following
precautions:
•Because of restricted chain clearance between tires and other
suspension components, it is important that only chains in
good condition are used. Broken chains can cause serious
damage. Stop the vehicle immediately if noise occurs that
could indicate chain breakage. Remove the damaged parts of
the chain before further use.
•Install chains on the front wheels as tightly as possible and
then retighten after driving about12mile (0.8 km).
•Do not exceed 45 mph (70 km/h).
•Drive cautiously and avoid severe turns and large bumps,
especially with a loaded vehicle.
•If chains are used on an All Wheel Drive (AWD) vehicle, they
should be used on all four tires.
•Do not drive for prolonged period on dry pavement.
•Observe the tire chain manufacturer’s instructions on the
method of installation, operating speed, and conditions for
use. Always use the lower suggested operating speed of the
chain manufacturer if different than the speed recommended
by the manufacture.
306 STARTING AND OPERATING

Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and front
and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to insure that it
is not over the GVWR.
Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle’s
GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight, axle by axle and side by side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is within
the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
328 STARTING AND OPERATING

WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
•When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
•Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
P for Park. Always, block orchockthe trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR

location.Do not raise the vehicle until you are sure the
jack is securely engaged. Never jack up the vehicle
using any suspension components.
6. Raise the vehicle by turning the jack screw to the right,
using the swivel wrench. Raise the vehicle only until the
tire just clears the surface and enough clearance is
obtained to install the spare tire. Minimum tire lift
provides maximum stability.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
7. Remove the wheel lug nuts, for vehicles with wheel
covers, remove the cover from the wheel by hand. Do not
pry the wheel cover off. Then pull the wheel off the hub.
8. Install the spare wheel, for vehicles with wheel covers,
align the notch in the wheel cover with the valve stem on
the wheel. Install the cover on the wheel by hand only
and install the wheel lug nuts with the cone shaped end
of the nut toward the wheel. Lightly tighten the lug nuts.
To avoid the risk of forcing the vehicle off the jack, do not
tighten the lug nuts fully until the vehicle has been
lowered.
NOTE:Do not install the wheel cover on the compact
spare.
Do not use a hammer or force to install the wheel covers.
9. Lower the vehicle by turning the jack screw to the left.
10. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate

362 MAINTAINING YOUR VEHICLE

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 Fluids, Lubricants, and Genuine Parts
for correct fluid type.
Front & Rear Suspension Ball Joints
The suspension ball joints are permanently sealed. No
regular maintenance is required for these components.
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 with a multi-purpose grease.
Mopar multi-purpose lubricant is recommended.
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.
