symbol (Fig. 4) on the label. At the bottom of the
NLGI symbol is the usage and quality identification
letters. Wheel bearing lubricant is identified by the
letter ªGº. Chassis lubricant is identified by the letter
ªLº. The letter following the usage letter indicates
the quality of the lubricant. The following symbols
indicate the highest quality.
SPECIALIZED LUBRICANTS AND OILS
Some maintenance or repair procedures may
require the use of specialized lubricants or oils. Con-
sult the appropriate sections in this manual for the
correct application of these lubricants.
DESCRIPTION - ENGINE COOLANT
WARNING: ANTIFREEZE IS AN ETHYLENE GLYCOL
BASE COOLANT AND IS HARMFUL IF SWAL-
LOWED OR INHALED. IF SWALLOWED, DRINK
TWO GLASSES OF WATER AND INDUCE VOMIT-
ING. IF INHALED, MOVE TO FRESH AIR AREA.
SEEK MEDICAL ATTENTION IMMEDIATELY. DO NOT
STORE IN OPEN OR UNMARKED CONTAINERS.
WASH SKIN AND CLOTHING THOROUGHLY AFTER
COMING IN CONTACT WITH ETHYLENE GLYCOL.
KEEP OUT OF REACH OF CHILDREN. DISPOSE OF
GLYCOL BASE COOLANT PROPERLY, CONTACT
YOUR DEALER OR GOVERNMENT AGENCY FOR
LOCATION OF COLLECTION CENTER IN YOUR
AREA. DO NOT OPEN A COOLING SYSTEM WHEN
THE ENGINE IS AT OPERATING TEMPERATURE OR
HOT UNDER PRESSURE, PERSONAL INJURY CAN
RESULT. AVOID RADIATOR COOLING FAN WHEN
ENGINE COMPARTMENT RELATED SERVICE IS
PERFORMED, PERSONAL INJURY CAN RESULT.
CAUTION: Use of Propylene Glycol based coolants
is not recommended, as they provide less freeze
protection and less boiling protection.The cooling system is designed around the coolant.
The coolant must accept heat from engine metal, in
the cylinder head area near the exhaust valves and
engine block. Then coolant carries the heat to the
radiator where the tube/fin radiator can transfer the
heat to the air.
The use of aluminum cylinder blocks, cylinder
heads, and water pumps requires special corrosion
protection. MopartAntifreeze/Coolant, 5
Year/100,000 Mile Formula (MS-9769), or the equiva-
lent ethylene glycol base coolant with hybrid organic
corrosion inhibitors (called HOAT, for Hybrid Organic
Additive Technology) is recommended. This coolant
offers the best engine cooling without corrosion when
mixed with 50% Ethylene Glycol and 50% distilled
water to obtain a freeze point of -37ÉC (-35ÉF). If it
loses color or becomes contaminated, drain, flush,
and replace with fresh properly mixed coolant solu-
tion.
The green coolantMUST NOT BE MIXEDwith
the orange or magenta coolants. When replacing cool-
ant the complete system flush must be performed
before using the replacement coolant.
CAUTION: MoparTAntifreeze/Coolant, 5
Year/100,000 Mile Formula (MS-9769) may not be
mixed with any other type of antifreeze. Doing so
will reduce the corrosion protection and may result
in premature water pump seal failure. If non-HOAT
coolant is introduced into the cooling system in an
emergency, it should be replaced with the specified
coolant as soon as possible.

HUB / BEARING
DESCRIPTION
The front wheel bearing and front wheel hub of
this vehicle are a hub and bearing unit type assem-
bly (Unit III). This unit combines the front wheel
mounting hub (flange) and the front wheel bearing
into a sealed one-piece unit. The hub and bearing is
mounted to the center of the steering knuckle (Fig.
1). It is retained by four mounting bolts accessible
from the inboard side of the steering knuckle. The
hub flange has five wheel mounting studs.
The wheel mounting studs used to mount the tire
and wheel to the vehicle are the only replaceable
components of the hub and bearing assembly. Other-
wise, the hub and bearing is serviced only as a com-
plete assembly.
OPERATION
The hub and bearing has internal bearings that
allow the hub to rotate with the driveshaft, along
with the tire and wheel. The five wheel mounting
studs mount the tire and wheel, and brake rotor to
the vehicle.
DIAGNOSIS AND TESTING - HUB AND
BEARING
The condition of the front hub and bearing assem-
bly is diagnosed using the inspection and testing pro-
cedure detailed below.
The bearing contained in the Unit III front hub/
bearing assembly will produce noise and vibration
when worn or damaged. The noise will generally
change when the bearings are loaded. A road test of
the vehicle is normally required to determine the
location of a worn or damaged bearing.
Find a smooth level road surface and bring the
vehicle up to a constant speed. When vehicle is at a
constant speed, swerve the vehicle back and forth
from the left and to the right. This will load and
unload the bearings and change the noise level.
When bearing damage is slight, the noise is some-
times noticeable at lower speeds and at other times
is more noticeable at speeds above 105 km/h (65
mph).
REMOVAL
NOTE: Replacement of the Unit III front hub/bearing
assembly can be normally done without having to
remove the steering knuckle from the vehicle. In the
event that the hub/bearing is frozen in the steering
knuckle and cannot be removed by hand, it will
have to be pressed out of the steering knuckle. The
steering knuckle will require removal from the vehi-
cle to allow the hub/bearing assembly to bepressed out of the steering knuckle. (Refer to 2 -

LOWER BALL JOINT
DESCRIPTION
The ball joint is an integral part of the lower con-
trol arm (Fig. 1). The ball joint has a tapered stud
that is pressed into the aluminum knuckle. The ball
joint stud is threaded on the end for a retainer nut.
The ball joint has a non-vented seal boot. The seal
boot has an integrated heat shield.
The ball joint used in the lower control arm of this
vehicle is a sealed-for-life ball joint and requires no
maintenance lubrication. The ball joint has been
lubricated-for-life during the manufacturing process.
A special fitting cap is installed on the fill port. This
cap must not be removed and replaced with a com-
mon zirc fitting. The special cap is there to eliminate
the possibility of lubrication latter during the ball
joints life, thus damaging the non-vented seal boot.
NOTE: The ball joint does not require any type of
additional lubrication for the life of the vehicle. No
attempt should be made to ever add any lubrication
to the lower ball joint.
OPERATION
The ball joint is a pivotal joint on the lower control
arm that allows the knuckle to move up and down,
and turn with ease.
DIAGNOSIS AND TESTING - LOWER BALL
JOINT
With the weight of the vehicle resting on the road
wheels, grasp the special fitting cap on the bottom of
the ball joint and with no mechanical assistance or
added force, attempt to rotate the grease fitting.
If the ball joint is worn, the grease fitting will
rotate easily. If movement is noted, replacement of
the control arm is recommended.
LOWER BALL JOINT SEAL
BOOT
DESCRIPTION - EXPORT
The lower ball joint seal boot is a two piece unit. It
consists of the seal boot, plus a separate shield that
is located in a groove at the top of the seal boot.
NOTE: The seal boot should only be replaced if
damaged during vehicle service. The entire lower
control arm should be replaced if the joint has been
contaminated.

(10) Remove the dust shield and jounce bumper as
an assembly from the strut shaft by pulling both
straight up and off the strut shaft. The dust shield
cannot be separated from the jounce bumper until
after it is removed from strut shaft.
(11) Remove the jounce bumper from the dust
shield. The jounce bumper is removed from the dust
shield by collapsing the dust shield until the jounce
bumper can be pulled free from the dust boot.
(12) Remove the spring isolator from the lower
spring seat on the strut (Fig. 38).
(13) Inspect the strut assembly components (Fig.
38) for the following and replace as necessary:
²Inspect the strut for any condition of shaft bind-
ing over the full stroke of the shaft.
²Check the upper mount for cracks and distortion
and its retaining studs for any sign of damage.
²Check the upper seat for stress cracks and wear.
²Check the upper spring isolator for severe dete-
rioration.
²Check for binding of the strut assembly pivot
bearing.
²Inspect the dust shield for rips and deteriora-
tion.
²Inspect the jounce bumper for cracks and signs
of deterioration.
ASSEMBLY - STRUT ASSEMBLY
For the disassembly and assembly of the strut
assembly, use of Strut Spring Compressor, Pentastar
Service Equipment (PSE) tool W-7200, or the equiva-
lent, is recommended to compress the coil spring.
Follow the manufacturer's instructions closely.
NOTE: Coil Springs on this vehicle are side-ori-
ented. Springs on the left side of the vehicle have a
left-hand wind top-to-bottom while springs on the
right side have a right-hand wind top-to-bottom.
Left and right springs must not be interchanged.
NOTE: If the coil spring has been removed from the
spring compressor, proceed with the next step, oth-
erwise, proceed with step 5.
(1) Place the coil spring in the compressor lower
hooks following the manufacturers instructions.
Proper orientation of the spring to the strut (once
installed) is necessary. Consider the following when
placing the coil spring in the compressor: From
above, the compressor back is at the 12 o'clock posi-
tion, and you, standing in the front of the machine,
are at the 6 o'clock position. Place the lower coil
spring end at the 6 o'clock position for both left and
right springs. (Fig. 46).
(2) Install the upper seat and upper isolator on top
of the coil spring. Position the notch in the perimeterof the upper seat toward the front of the compressor
(same 6 o'clock position as in step 1).
(3) Position the upper hooks on top of the coil
spring upper seat so the upper hooks span approxi-
mately 1 inch past outside diameter of upper seat
(Fig. 47). This will allow proper clearance for upper
mount installation without pinching the hooks in-be-
tween the two pieces.Do not allow hooks to be
placed closer to edge.
(4) Compress the coil spring far enough to allow
strut installation.
(5) If the pivot bearing has been removed from the
upper seat, install the pivot bearing on the top of the
upper spring seat (Fig. 48). The bearing must be
installed on upper seat with the smaller diameter

side of the pivot bearing toward the spring seat. Be
sure the pivot bearing is sitting flat on the spring
seat once mounted.
(6) Install the spring isolator on the lower spring
seat of the strut (Fig. 38).
(7) Install the jounce bumper on the strut shaft
(Fig. 38). The jounce bumper is to be installed with
the small end pointing downward.
(8) Install the dust shield on the strut. Collapse
and stretch the dust shield down over the top of the
jounce bumper until the dust shield snaps into the
slot on the jounce bumper. The jounce bumper will be
at the top of the inner dust boot. Return the dust
shield to its fully extended length.
(9) Install the strut through the bottom of the coil
spring until the lower spring seat contacts the lower
end of the coil spring. The clevis bracket on the strut
should point straight outward away from the com-
pressor (to the 6 o'clock position). This position
should be within 5É of the lower end tip of the coil
spring (Fig. 49). If necessary, reposition the strut or
coil spring in the compressor so both of these line up
straight outward away from the compressor (to the 6
o'clock position). Install the clamp to hold the strut
and coil together.
(10) Install the strut mount over the strut shaft
and onto the top of the pivot bearing and upper seat
as shown (Fig. 44). Loosely install the retaining nut
on the strut shaft.
(11) Install Strut Nut Socket (on the end of a
torque wrench), Special Tool 6864, on the strut shaft
retaining nut (Fig. 45). Next, install a 10 mm socket
on the hex on the end of the strut shaft. While hold-
ing the strut shaft from turning, tighten the strut
shaft retaining nut to a torque of 100 N´m (75 ft.
lbs.).NOTE: Before releasing the tension the compressor
has on the spring, using the following figure as ref-
erence (Fig. 50), make sure the upper spring seat,
coil spring and strut clevis bracket are all lined up
properly (within 5É of one another).
(12) Slowly release the tension from the coil spring
by backing off the compressor drive fully. As the ten-
