STANDARD PROCEDURE
STANDARD PROCEDURE - WHEEL ALIGNMENT
PRE-WHEEL ALIGNMENT INSPECTION
Before any attempt is made to change or correct
the wheel alignment, the following inspection and
necessary corrections must be made to ensure proper
alignment.
(1) Verify that the fuel tank is full of fuel. If the
tank is not full, the reduction in weight will affect
the curb height of the vehicle and the alignment
angles.
(2) The passenger and luggage compartments of
the vehicle should be free of any load that is not fac-
tory equipment.
(3) Check the tires on the vehicle. All tires must be
the same size and in good condition with approxi-
mately the same amount of tread wear. Inflate all
the tires to the recommended air pressure.
(4) Check the front wheel and tire assemblies for
excessive radial runout.(5) Inspect lower ball joints and all steering link-
age for looseness, binding, wear or damage. Repair as
necessary.
(6) Check suspension fasteners for proper torque
and retighten as necessary.
(7) Inspect all suspension component rubber bush-
ings for signs of wear or deterioration. Replace any
faulty bushings or components before aligning the
vehicle.
(8) Check the vehicle's curb height to verify it is
within specifications. Refer to Curb Height Measure-
ment.
WHEEL ALIGNMENT SETUP
(1) Position the vehicle on an alignment rack.
(2) Install all required alignment equipment on
the vehicle per the alignment equipment manufactur-
er's instructions. On this vehicle, a four-wheel align-
ment is recommended.
2 - 52 WHEEL ALIGNMENTRS
WHEEL ALIGNMENT (Continued)

NOTE: Prior to reading the vehicle's alignment
readouts, the front and rear of vehicle should be
jounced. Induce jounce (rear first, then front) by
grasping the center of the bumper and jouncing
each end of vehicle an equal number of times. The
bumper should always be released when vehicle is
at the bottom of the jounce cycle.
(3) Read the vehicle's current front and rear align-
ment settings. Compare the vehicle's current align-
ment settings to the vehicle specifications for camber,
caster and toe-in. (Refer to 2 - SUSPENSION/
WHEEL ALIGNMENT - SPECIFICATIONS)
(4) If front camber and caster are not within spec-
ifications, proceed to CAMBER AND CASTER below.
If caster and camber are within specifications, pro-
ceed to TOE which can be found following CAMBER
AND CASTER. Rear camber, caster and toe are not
adjustable. If found not to be within specifications,
reinspect for damaged suspension or body compo-
nents and replace as necessary.
CAMBER AND CASTER
Camber and caster settings on this vehicle are
determined at the time the vehicle is designed, by
the location of the vehicle's suspension components.
This is referred to as NET BUILD. The result is no
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 brackethas 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
assembly. If necessary use a wire hanger to sup-
port the steering knuckle assembly or if required
remove the brake flex hose from the caliper assem-
bly.
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).

(11) If toe readings obtained are not within the
required specification range, adjust toe to meet the
preferred specification setting. Toe is adjustable
using the following procedure.
TOE
(1) Center the steering wheel and lock in place
using a steering wheel clamp.
CAUTION: Do not twist front inner tie rod to steer-
ing gear rubber boots during front wheel Toe
adjustment.
(2) Loosen front inner to outer tie rod end jam
nuts (Fig. 12). Grasp inner tie rods at serrations and
rotate inner tie rods of steering gear (Fig. 12) to set
front toe to the preferred toe specification. (Refer to 2
- SUSPENSION/WHEEL ALIGNMENT - SPECIFI-
CATIONS)
(3) Tighten tie rod jam nuts (Fig. 12) to 75 N´m
(55 ft. lbs.) torque.
(4) Adjust steering gear to tie rod boots at the
inner tie rod.
(5) Remove steering wheel clamp.
(6) Remove the alignment equipment.
(7) Road test the vehicle to verify the steering
wheel is straight and the vehicle does not wander or
pull.
STANDARD PROCEDURE - CURB HEIGHT
MEASUREMENT
The wheel alignment is to be checked and all align-
ment adjustments made with the vehicle at its
required curb height specification.
Vehicle height is to be checked with the vehicle on
a flat, level surface, preferably a vehicle alignment
rack. The tires are to be inflated to the recommended
pressure. All tires are to be the same size as stan-
dard equipment. Vehicle height is checked with the
fuel tank full of fuel, and no passenger or luggage
compartment load.
Vehicle height is not adjustable. If the measure-
ment is not within specifications, inspect the vehicle
for bent or weak suspension components. Compare
the parts tag on the suspect coil spring(s) to the
parts book and the vehicle sales code, checking for a
match. Once removed from the vehicle, compare the
coil spring height to a correct new or known good coil
spring. The heights should vary if the suspect spring
is weak.
(1) Measure from the inboard edge of the wheel
opening fender lip directly above the wheel center
(spindle), to the floor or alignment rack surface.
(2) When measuring, the maximum left-to-right
differential is not to exceed 12.5 mm (0.5 in.).
(3) Compare the measurements to the specifica-
tions listed in the following Curb Height Specifica-
tions charts.

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.

The hydraulic diagram (Fig. 7) shows the vehicle in
the ABS braking mode. The diagram shows one
wheel is slipping because the driver is attempting to
stop the vehicle at a faster rate than is allowed by
the surface on which the tires are riding.
²The normally open and normally closed valves
modulate (build/decay) the brake hydraulic pressure
as required.
²The pump/motor is switched on so that the
brake fluid from the low pressure accumulators is
returned to the master cylinder circuits.
²The brake fluid is routed to either the master
cylinder or the wheel brake depending on the posi-
tion of the normally open valve.
