GENERAL INFORMATION
INTRODUCTION
Service and maintenance procedures for compo-
nents and systems listed in Schedule ± A or B can be
found by using the Group Tab Locator index at the
front of this manual. If it is not clear which group
contains the information needed, refer to the index at
the back of this manual.
There are two maintenance schedules that show
proper service based on the conditions that the vehi-
cle is subjected to.
Schedule ±A, lists scheduled maintenance to be
performed when the vehicle is used for general trans-
portation.
Schedule ±B, lists maintenance intervals for vehi-
cles that are operated under the conditions listed at

STEERING KNUCKLE
The front suspension knuckle is not a repairable
component of the vehicles front suspensionIT MUST
BE REPLACED.If bent, broken or damaged in any
way, do not attempt to straighten or repair the steer-
ing knuckle.
Service replacement of the front hub/bearing
assembly can be done with the front steering knuckle
remaining on the vehicle.
LOWER CONTROL ARM
If damaged, the lower control arm casting is ser-
viced only as a complete component. Inspect lower
control arm for signs of damage from contact with
the ground or road debris. If lower control arm shows
any sign of damage, inspect lower control arm for
distortion.Do not attempt to repair or straighten
a broken or bent lower control arm.
The serviceable components of the lower control
arm are: the ball joint assembly, ball joint assembly
grease seal and control arm bushings. Inspect both
control arm bushings for severe deterioration, and
replace if required. Inspect ball joint per inspection
procedure in this section of the service manual and
replace if required. Service procedures to replace
these components are detailed in the specific compo-
nent removal and installation sections in this group
of the service manual.
BALL JOINT (LOWER)
With the weight of the vehicle resting on the road
wheels, grasp the grease fitting as shown in (Fig. 5)
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 ball joint is recommended.
STABILIZER BAR
Inspect for broken or distorted sway bar bushings,
bushing retainers, and worn or damaged sway bar to
strut attaching links. If sway bar to front suspension
cradle bushing replacement is required, bushing can
be removed from sway bar by opening slit and peel-
ing bushing off sway bar.
HUB AND BEARING ASSEMBLY
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.
Where axle bearing damage is slight, the noise is
usually not noticeable at speeds above 30 m.p.h..
SERVICE PROCEDURES
SUSPENSION CRADLE THREAD REPAIR
PROCEDURE
WARNING: When performing this procedure use
only the thread inserts which are specified in the
Mopar Parts Catalog for this repair procedure.
These thread inserts have been specifically devel-
oped for this application and use of other types of
thread inserts can result in an inferior long term
repair.
The threaded holes in the front suspension cradle,
if damaged, can repaired by installing a Heli-Coilt
thread insert.
The threaded holes that are repairable using the
thread insert, are the lower control arm rear bushing
retainer mounting bolt holes, routing bracket attach-
ing locations for the power steering hoses, and brake
hose attachment holes.
This repair procedure now allows the threaded
holes in the suspension crossmember to be repaired,
eliminating the need to replace the crossmember if
damage occurs to one of the threaded holes.
The thread inserts for this application are specified
by part number in the Mopar Parts Catalog.Do not
use a substitute thread insert.
The specific tools and equipment required to install
the thread insert are listed below. Refer to the
Fig. 5 Checking Ball Joint Wear
2 - 12 SUSPENSIONNS
DIAGNOSIS AND TESTING (Continued)

SERVICE PROCEDURES
MASTER CYLINDER FLUID LEVEL CHECK
Check master cylinder reservoir fluid level a mini-
mum of twice annually.
Master cylinder reservoirs are marked with the
words FULL and ADD to indicate proper brake fluid
fill level of the master cylinder (Fig. 26).
If necessary, add brake fluid to bring the level to
the bottom of the FULL mark on the side of the mas-
ter cylinder fluid reservoir.When filling master
cylinder fluid reservoir do not fill the filler
neck of the fluid reservoir (Fig. 26) with brake
fluid.
Use only Mopartbrake fluid or an equivalent from
a sealed container. Brake fluid must conform to DOT
3, specifications.
DO NOTuse brake fluid with a lower boiling
point, as brake failure could result during prolonged
hard braking.
Use only brake fluid that was stored in a tightly-
sealed container.
DO NOTuse petroleum-based fluid because seal
damage will result. Petroleum based fluids would be
items such as engine oil, transmission fluid, power
steering fluid ect.
BLEEDING BASE BRAKE HYDRAULIC SYSTEM
NOTE: This bleeding procedure is only for the vehi-
cle's base brakes hydraulic system. For bleeding
the antilock brakes hydraulic system, refer to the
ITT Teves Mark 20 Antilock Brake System bleeding
procedure in the antilock brakes section of this ser-
vice manual.
PRESSURE BLEEDING PROCEDURE
CAUTION: Before removing the master cylinder
cover, throughly clean the cover and master cylin-
der fluid reservoir to prevent dirt and other foreign
matter from dropping into the master cylinder fluid
reservoir.
CAUTION: Use bleeder tank Special Tool C-3496-B
with adapter Special Tool 6921 to pressurize the
hydraulic system for bleeding.
CAUTION: When pressure bleeding the brakes
hydraulic system the fluid reservoir filler neck must
be removed from the master cylinder fluid reservoir.
Failure to remove the filler neck from the fluid res-
ervoir, may result in the filler neck separating from
the fluid reservoir when the hydraulic system is
pressurized.
Follow pressure bleeder manufacturer's instruc-
tions, for use of pressure bleeding equipment.
When bleeding the brake system, some air may be
trapped in the brake lines or valves far upstream, as
much as ten feet from the bleeder screw (Fig. 27).
Therefore, it is essential to have a fast flow of a large
volume of brake fluid when bleeding the brakes to
ensure all the air gets out.
(1) Remove the filler neck from the master cylin-
der fluid reservoir.
(2) Install the Adapter Master Cylinder Pressure
Bleed Cap, Special Tool 6921 on the fluid reservoir of
the master cylinder (Fig. 28). Attach the fluid hose
from the pressure bleeder to the fitting on Special
Tool 6921.
(3) Attach a clear plastic hose to the bleeder screw
at one wheel and feed the hose into a clear jar con-
taining fresh brake fluid.

REAR DRUM BRAKE WHEEL CYLINDER
With brake drums removed, inspect the wheel cyl-
inder boots for evidence of a brake fluid leak. Visu-
ally check the boots for cuts, tears, or heat cracks. If
any of these conditions exist, the wheel cylinders
should be completely cleaned, inspected and new
parts installed.
If a wheel cylinder is leaking and the brake lining
material is saturated with brake fluid, the brake
shoes must be replaced.
BRAKE HOSE AND BRAKE LINES INSPECTION
Flexible rubber hose is used at both front brakes
and at the rear axle. Inspection of brake hoses
should be performed whenever the brake system is
serviced and every 7,500 miles or 12 months, which-
ever comes first (every engine oil change). Inspect
hydraulic brake hoses for surface cracking, scuffing,
or worn spots. If the fabric casing of the rubber hose
becomes exposed due to cracks or abrasions in the
rubber hose cover, the hose should be replaced imme-
diately. Eventual deterioration of the hose can take
place with possible burst failure. Faulty installation
can cause twisting, resulting in wheel, tire, or chassis
interference.
The steel brake tubing should be inspected period-
ically for evidence of physical damage or contact with
moving or hot components.
The flexible brake tube sections used on this vehi-
cle in the primary and secondary tubes from the
master cylinder to the ABS hydraulic control unit
connections and the chassis brake tubes between the
hydraulic control unit and the proportioning valve
must also be inspected. This flexible tubing must be
inspected for kinks, fraying and its contact with
other components of the vehicle or contact with the
body of the vehicle.
REAR WHEEL HUB AND BEARING ASSEMBLY
The rear hub and bearing assembly is designed for
the life of the vehicle and should require no mainte-
nance. The following procedure may be used for eval-
uation of bearing condition.
With wheel and brake drum removed, rotate
flanged outer ring of hub. Excessive roughness, lat-
eral play or resistance to rotation may indicate dirt
intrusion or bearing failure. If the rear wheel bear-
ings exhibit these conditions during inspection, the
hub and bearing assembly should be replaced.
Damaged bearing seals and resulting excessive
grease loss may also require bearing replacement.
Moderate grease loss from bearing is considered nor-
mal and should not require replacement of the hub
and bearing assembly.
ADJUSTMENTS
STOP LAMP SWITCH
(1) Remove stop lamp switch from its bracket by
rotating it approximately 30É in a counter-clockwise
direction.
(2) Disconnect wiring harness connector from stop
lamp switch.
(3) Hold stop lamp switch firmly in one hand.
Then using other hand, pull outward on the plunger
of the stop lamp switch until it has ratcheted out to
its fully extended position.
(4) Install the stop lamp switch into the bracket
using the following procedure. Depress the brake
pedal as far down as possible. Then while keeping
the brake pedal depressed, install the stop lamp
switch into the bracket by aligning index key on
switch with slot at top of square hole in mounting
bracket. When switch is fully installed in the square
hole of the bracket, rotate switch clockwise approxi-
mately 30É to lock the switch into the bracket.
CAUTION: Do not use excessive force when pulling
back on brake pedal to adjust the stop lamp switch.
If too much force is used, damage to the vacuum
booster, stop lamp switch or striker (Fig. 195) can
result.
(5) Connect the wiring harness connector to the
stop lamp switch.
(6) Gently pull back on brake pedal until the pedal
stops moving. This will cause the switch plunger
(Fig. 195) to ratchet backward to the correct position.
