HALF SHAFT - FRONT
DESCRIPTION
All vehicles use an unequal length half shaft sys-
tem (Fig. 1).
The left half shaft uses a tuned rubber damper
weight. When replacing the left half shaft, be sure
the replacement half shaft has the same damper
weight as the original.
All half shaft assemblies use the same type of
inner and outer joints. The inner joint of both half
shaft assemblies is a tripod joint, and the outer joint
of both half shaft assemblies is a Rzeppa joint. Both
tripod joints and Rzeppa joints are true constant
velocity (CV) joint assemblies. The inner tripod joint
allows for the changes in half shaft length through
the jounce and rebound travel of the front suspen-
sion.
On vehicles equipped with ABS brakes, the outer
CV joint is equipped with a tone wheel used to deter-
mine vehicle speed for ABS brake operation.
The inner tripod joint of both half shafts is splined
into the transaxle side gears. The inner tripod joints
are retained in the side gears of the transaxle using
a snap ring located in the stub shaft of the tripod
joint. The outer CV joint has a stub shaft that is
splined into the wheel hub and retained by a steel
hub nut.
DIAGNOSIS AND TESTING - HALF SHAFT
VEHICLE INSPECTION
(1) Check for grease in the vicinity of the inboard
tripod joint and outboard CV joint; this is a sign of
inner or outer joint seal boot or seal boot clamp dam-
age.
NOISE AND/OR VIBRATION IN TURNS
A clicking noise and/or a vibration in turns could
be caused by one of the following conditions:
²Damaged outer CV or inner tripod joint seal
boot or seal boot clamps. This will result in the loss
and/or contamination of the joint grease, resulting in
inadequate lubrication of the joint.
²Noise may also be caused by another component
of the vehicle coming in contact with the half shafts.
CLUNKING NOISE DURING ACCELERATION
This noise may be a result of one of the following
conditions:
²A torn seal boot on the inner or outer joint of the
half shaft assembly.
²A loose or missing clamp on the inner or outer
joint of the half shaft assembly.
²A damaged or worn half shaft CV joint.
SHUDDER OR VIBRATION DURING ACCELERATION
This problem could be a result of:
²A worn or damaged half shaft inner tripod joint.
RSDIFFERENTIAL & DRIVELINE3-1

²A sticking tripod joint spider assembly (inner tri-
pod joint only).
²Improper wheel alignment. (Refer to 2 - SUS-
PENSION/WHEEL ALIGNMENT - STANDARD
PROCEDURE)
VIBRATION AT HIGHWAY SPEEDS
This problem could be a result of:
²Foreign material (mud, etc.) packed on the back-
side of the wheel(s).
²Out of balance tires or wheels. (Refer to 22 -
TIRES/WHEELS - STANDARD PROCEDURE)
²Improper tire and/or wheel runout. (Refer to 22 -
TIRES/WHEELS - DIAGNOSIS AND TESTING)
REMOVAL
(1) Raise vehicle.
(2) Remove the cotter pin, nut lock (Fig. 2) and
wave washer (Fig. 3) from the end of the half shaft.
(3) Remove the wheel and tire assembly from the
vehicle. (Refer to 22 - TIRES/WHEELS - REMOVAL)
CAUTION: The halfshaft outer CV Joint, when
installed, acts as a bolt and secures the hub/bear-
ing assembly. If the vehicle is to be supported or
moved while the halfshaft is removed, it is neces-sary to install and properly torque a bolt through
the hub. This will ensure that the hub/bearing
assembly will not loosen.

ANTENNA BODY AND CABLE
DESCRIPTION
Domestic vehicles use a fixed-length stainless steel
rod-type antenna mast, installed at the right front
fender of the vehicle. The antenna mast is connected
to the center wire of the coaxial antenna cable, and is
not grounded to any part of the vehicle.
OPERATION
To minimize static, the antenna base must have a
good ground. The coaxial antenna cable shield (the
outer wire mesh of the cable) is grounded to the
antenna base and the radio chassis.
The antenna coaxial cable has an additional dis-
connect, located near the right end of the instrument
panel. This additional disconnect allows the instru-
ment panel assembly to be removed and installed
without removing the radio.

DESCRIPTION
The antenna module is an electromagnetic circuit
component designed to capture and enhance RF
(Radio Frequency) signals in both the AM and FM
broadcast bands. The antenna module is mounted to
the right rear roof rail under the headliner. The mod-
ule is grounded through the mounting bracket and
fastener. The module has a two wire electrical con-
nector that connects to the integral radio antenna,located on the right rear quarter glass. There is also
an electrical connector for battery voltage and a coax
cable connector.OPERATION
The antenna module receives both AM and FM
radio signals supplied by the side window integral

PARK ASSIST SYSTEM
The Park Assist System display activates an audi-
ble tone that changes from intermittent to continu-
ous as the final two Light Emitting Diodes (LED's)
are illuminated on one side or both sides of the dis-
play.
The system detection length from the rear of the
vehicle is 0.3 meters to 1.5 meters. This area extends
around the rear side of the vehicle. The system detec-
tion height from the ground is 0.2 meters to about
1.5 meters. The radio mutes when the system acti-
vates its audible tone.
When the driver selects Reverse the system scans
for objects behind the vehicle using four sensors
located in the rear bumper. A warning display above
the rear window provides both visible and audible
warnings indicating the range of the object.
The system is active only when the transmission
gear selector is in reverse for vehicle speeds less than
16 Km/h (10 mph). If the vehicle's Parking/Emer-
gency Brake is applied, the system is deactivated.
The display contains two sets of yellow and red
Light Emitting Diode's (LED's) that the driver can
see as they look over their shoulder while backing
up. Each side of the vehicle has its own warning
LED's. The system provides a visual warning by illu-
minating one or more yellow LED's as the vehicle
gets closer to the object. As the vehicle continues to
approach the object, one red LED is illuminated and
the system emits a series of short beeps. The tone
will remain constant and both red LED's are illumi-
nated once the vehicle is within 12 inches (30.5 cm)
of the object.
The system can be turned ON or OFF through the
Electronic Vehicle Information Center (EVIC) when
the vehicle is in PARK. If the park assist system is
turned OFF, a single chime will sound and the EVIC
will display the following message ªREAR PARK
ASSIST OFFº, when the vehicle is in reverse.
²Ensure that the rear bumper is free of dirt and
debris to keep the system operating properly.
²Jackhammers, large trucks, and other vibrations
could affect the performance of the system.
²Ensure that the parking brake is not applied.
If ªService Park Assist Systemº appears in the
EVIC after making sure the rear bumper is clean,
proceed to diagnose the system using a scan tool and
the appropriate diagnostic information.
WARNING
On vehicles equipped with airbags, disable
the airbag system before attempting any steer-
ing wheel, steering column, or instrument
panel component diagnosis or service. Discon-
nect and isolate the battery negative (ground)
cable, then wait two minutes for the airbag sys-
tem capacitor to discharge before performing
further diagnosis or service. This is the only
sure way to disable the airbag system. Failure
to take the proper precautions could result in
accidental airbag deployment, personal injury,
or death.

PARK ASSIST SENSOR
DESCRIPTION
The Park Assist Sensors are located in the rear
bumper fascia mounted equally apart (Fig. 5). The
sensors generate ultrasonic pulses when triggered by
the park assist module when an obstacle is detected.
The sensors then signal the module when reflected
ultrasonic pulses are received.
The sensors detect objects with an ultrasonic pulse
that reflects off the object and then is sent to the
module to determine the distance of the object.
OPERATION
The Park Assist Sensors:
²Generate ultrasonic pulses when triggered by
the Park Assist Module.
²Reception/filtering of ultrasonic energy received.
²Signalling the module of received ultrasonic
pulses that meet threshold criteria.
The sensors are supplied power by the module. The
sensor supply is enabled when the sensor function is
necessary.
The sensors detection length from the rear of the
vehicle is 0.3 meters to 1.5 meters. This area extends
around the rear side of the vehicle. The sensor detec-
tion height from the ground is 0.2 meters to about
1.5 meters.
