required adjustment of camber and caster after the
vehicle is built or when servicing the suspension
components. Thus, when performing a wheel align-
ment, caster and camber are not normally considered
adjustable angles. Camber and caster should be
checked to ensure they meet vehicle specifications.
If front camber is found not to meet alignment
specifications, it can be adjusted using an available
camber adjustment bolt package. Before installing a
camber adjustment bolt package on a vehicle found
to be outside the specifications, inspect the suspen-
sion components for any signs of damage or bending.
CAUTION: Do not attempt to adjust the vehicles
wheel alignment by heating, bending or by perform-
ing any other modification to the vehicle's front
suspension components or body.
If camber readings are not within specifications,
use the following procedure to install the front cam-
ber adjustment bolt package and then adjust front
camber.
CAMBER ADJUSTMENT BOLT PACKAGE INSTALLATION
The camber adjustment bolt package contains 2
flange bolts, 2 cam bolts, 2 dog bone washers, and 4
nuts. This package services both sides of the vehicle.
Use the package to attach the strut clevis bracket to
the steering knuckle after the strut clevis bracket
has been modified. To install and adjust the camber
adjustment bolt package, follow the procedure below.
(1) Raise the vehicle until its tires are not support-
ing the weight of the vehicle.
(2) Remove the front tire and wheel assemblies.
CAUTION:
When removing the steering knuckle from
the strut clevis bracket, do not put a strain on the
brake flex hose. Also, do not let the weight of the
steering knuckle assembly be supported by the
brake flex hose when removed from the strut assem-
bly. If necessary use a wire hanger to support the
steering knuckle assembly or if required remove the
brake flex hose from the caliper assembly.
CAUTION: The knuckle to strut assembly attaching
bolt shanks are serrated and must not be turned
during removal. Remove the nuts while holding the
bolts stationary.
(3) Remove the top and bottom, strut clevis
bracket to steering knuckle attaching bolts (Fig.
7)and discard. Separate the steering knuckle from
the strut clevis bracket and position steering knuckle
so it is out of the way of the strut.
CAUTION: When slotting the bottom mounting hole
on the strut clevis bracket, do not enlarge the hole
beyond the indentations on the sides of the strut
clevis bracket (Fig. 8).(4) Using an appropriate grinder and grinding
wheel, slot the bottom hole in both sides of the strut
clevis bracket (Fig. 8).
CAUTION: After slotting the strut clevis bracket
hole, do not install the original attaching bolts when
assembling the steering knuckle to the strut assem-
bly. Only the flange bolts, cam bolts, and dog bone
washers from the service package must be used to
attach the steering knuckle to the strut after the
mounting hole is slotted.

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.
RSDIFFERENTIAL & DRIVELINE3-1
SHUDDER OR VIBRATION DURING ACCELERATION
This problem could be a result of:
²A worn or damaged half shaft inner tripod joint.
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 -
