CLUTCH AND GEARSHIFT LINKAGE
If the clutch or gearshift begins to operate with dif-
ficulty, squeak or grunt, the cables and linkage
should be lubricated before service replacement is
performed. For proper lubrication and service proce-
dures refer to Group 6, Clutch, or Group 21, Manual
Transaxle.
MANUAL TRANSAXLE
The manual transaxle should be inspected for oil
leaks and proper oil level when other under vehicle
service is performed. To inspect the transaxle oil
level, position the vehicle on a level surface. Remove
fill plug (Fig. 1) from the transaxle side cover. The
oil level should not be below 4 mm (3/16 in) from the
bottom of the oil fill opening. The manual transaxle does not require periodic
maintenance. The oil should be changed only when
water contamination is suspected. If oil has a foamy
or milky appearance it probably is contaminated. A
circular magnet located behind the differential cover
collects metallic particles circulating in the oil. For
proper diagnostic and service procedures, refer to
Group 21, Manual Transaxle.
SELECTING MANUAL TRANSAXLE OIL
Chrysler Corporation recommends Mopar Engine
Oil, SG or SG/CD SAE 5W-30, or equivalent, be used
to fill a 5-speed transaxle.
AUTOMATIC TRANSAXLE FLOOR SHIFT
If the automatic transaxle floor shift mechanism
becomes difficult to operate or starts to make objec-
tionable noise, the mechanism should be lubricated
before service repair is performed. To lubricate the
shift mechanism, remove console as necessary. Refer
to Group 23, Body. Apply a film of Mopar Multipur-
pose Grease or equivalent, to slide surfaces and pawl
spring. For additional information, refer to Group 21,
Transaxle.
AUTOMATIC TRANSAXLE
The automatic transaxle should be inspected for
fluid leaks and proper fluid level when other under
hood service is performed.
CAUTION: To minimize fluid contamination, verify
that dipstick is seated in the fill hole or tube after
fluid level reading is taken.
TO INSPECT THE TRANSAXLE FLUID LEVEL: (1) Position the vehicle on a level surface.
(2) Start engine and allow to idle in PARK for at
least 60 seconds. The warmer the transaxle fluid, the
more accurate the reading. (3) While sitting in driver seat, apply brakes and
place gear selector in each position. Return gear se-
lector to park. (4) Raise hood and remove transaxle fluid level in-
dicator (dipstick) and wipe clean with a suitable
cloth. (5) Install dipstick and verify it is seated in fill
hole or tube (Fig. 2 or 3).
CAUTION: Do not overfill automatic transaxle, leak-
age or damage can result.
(6) Remove dipstick, with handle above tip, take
fluid level reading (Fig. 4). If the vehicle has been
driven for at least 15 minutes before inspecting fluid
level, transaxle can be considered hot and reading
should be above the WARM mark. If vehicle has run
for less than 15 minutes and more than 60 seconds
transaxle can be considered warm and reading

flakes are visible in the used lubricant or the bearing
rollers and race cup is discolored, the bearing and
race cup should be replaced. For proper service pro-
cedures, see Group 5, Brakes. Replace the inner seal
whenever the wheel bearings are serviced.
REAR WHEEL BEARING LUBRICATION
CAUTION: Combining two types of lubricant can
cause bearing failure. Wash used or new bearings
with a suitable solvent and blot dry with a lint free
cloth before packing with new lubricant.
WARNING: DO NOT ALLOW BEARING TO SPIN AT
HIGH RPM WHEN USING COMPRESSED AIR TO
BLOW CLEANING SOLVENT FROM BEARING.
BEARING CAGE CAN EXPLODE, CAUSING PER-
SONAL INJURY.
TO LUBRICATE REAR WHEEL BEARINGS:
(1) Hoist rear wheels off the ground and support ve-
hicle on safety stands. Refer to Hoisting Recommenda-
tions in the General Information section of this group.
(2) Remove rear wheels.
(3) Remove brake caliper on vehicles with rear disc
brakes. For proper procedure, see Group 5, Brakes. (4) Remove rear wheel hub (drum) assembly and
remove inner grease seal (Fig. 7). For proper service
procedure, see Group 5, Brakes. (5) Inspect bearings, refer to Inspection paragraph
of this procedure. Wash used lubricant from bearings
with solvent and blot or blow dry. (6) Using a bearing packing device, lubricate the
bearings with Mopar, Wheel Bearing Grease or
equivalent. (7) With a wiping cloth, clean used lubricant form
wheel hub assembly and axle spindle. (8) Install inner wheel bearing in the hub assem-
bly, small end of bearing toward hub. With a finger,
smooth out grease around the outside of bearing. (9) Using a seal driver, install new inner hub seal.
(10) Install wheel hub (drum) assembly on axle
spindle. (11) Install outer wheel bearing over the spindle
end, small end of bearing toward hub. With a finger,
smooth out grease around the outside of bearing. (12) Install washer and spindle nut. While rotating
hub, tighten spindle nut to 27 to 34 N Im (240 to 300
in. lbs.) torque. Loosen spindle nut one quarter turn.
Hand tighten spindle nut. (13) Install spindle nut lock cover, cotter pin and
grease cap. (14) Install disc brake caliper on vehicles with disc
brakes. CAUTION: Pump brake pedal several times before
driving vehicle to verify brake operation.
(15) Install wheel and lower vehicle.
BRAKES
BRAKE PAD AND LINING INSPECTION
The brake pads and linings should be inspected at dis-
tance intervals described in the Lubrication and Main-
tenance Schedules. Refer to the General Information
section of this group. If brake pads or linings appear ex-
cessively worn, the brakes would require service. For
proper service procedures, refer to Group 5, Brakes.
BRAKE HOSE INSPECTION
WARNING: IF FRONT WHEEL, REAR AXLE, OR AN-
TI-LOCK UNIT BRAKE HOSE OUTER COVER IS
CRACKED, CHAFED, OR BULGED, REPLACE HOSE
IMMEDIATELY. BRAKE FAILURE CAN RESULT.
The front wheel, rear axle and anti-lock unit (if
equipped) brake hoses should be inspected at time
and distance intervals described in the Lubrication
and Maintenance Schedules. Refer to the General In-
formation section of this group. A hose must be re-
placed if it has signs of cracking, chafing, fatigue or
bulging. For proper service procedures, refer to
Group 5, Brakes.

BRAKE RESERVOIR LEVEL INSPECTION
WARNING: DO NOT ALLOW PETROLEUM OR WATER
BASE LIQUIDS TO CONTAMINATE BRAKE FLUID,
SEAL DAMAGE AND BRAKE FAILURE CAN RESULT.
RELIEVE PRESSURE IN ANTI-LOCK BRAKE SYS-
TEM BEFORE ADDING BRAKE FLUID TO RESER-
VOIR. IF NOT, BRAKE FLUID COULD DISCHARGED
FROM THE RESERVOIR POSSIBLY CAUSING PER-
SONAL INJURY.
The brake reservoir level should be inspected when
other under hood service is performed. It is normal
for the reservoir level to drop as disc brake pads
wear. When fluid must be added, use Mopar, Brake
Fluid or equivalent. Use only brake fluid conforming
to DOT 3, Federal, Department of Transportation
specification. To avoid brake fluid contamination, use
fluid from a properly sealed container. On vehicles with anti-lock brakes, depressurize the
system before inspecting fluid level. Turn OFF the
ignition and remove the key. Pump the brake pedal
at least 50 times to relieve the pressure in the sys-
tem.
On all vehicles, if fluid should become low after sev-
eral thousand kilometers (miles), fill the reservoir to
level marks on the side of the reservoir (Fig. 8 or 9).
HEADLAMPS
The headlamps should be inspected for intensity
and aim whenever a problem is suspected. When lug-
gage compartment is heavily loaded, the headlamp
aim should be adjusted to compensate for vehicle
height change. For proper service procedures, refer to
Group 8L, Lamps. DRIVER SUPPLEMENTAL AIRBAG SYSTEM
If the AIRBAG indicator lamp does not light at all,
stays lit or lights momentarily or continuously while
driving, a malfunction may have occurred. Prompt service is required. Refer to Group 8M, Restraint
Systems for proper diagnostic procedures.
BODY LUBRICATION
Body mechanisms and linkages should be inspected,
cleaned and lubricated as required to maintain ease of
operation and to prevent corrosion and wear. Before a component is lubricated, oil, grease and dirt
should be wiped off. If necessary, use solvent to clean
component to be lubricated. After lubrication is com-
plete, wipe off excess grease or oil. During winter season, external lock cylinders should
be lubricated with Mopar, Lock Lubricant or equiva-
lent to ensure proper operation when exposed to water
and ice. To assure proper hood latching component operation,
use engine oil to lubricate the lock, safety catch and
hood hinges when other under hood service is per-
formed. Mopar, Multi-purpose Grease or equivalent
should be applied sparingly to all pivot and slide
contact areas.
USE ENGINE OIL ON:
² Door hingesÐHinge pin and pivot points.
² Hood hingesÐPivot points.
² Luggage compartment lid hingesÐPivot points.
USE MOPAR LUBRIPLATE OR EQUIVALENT ON:
² Door check straps.

lbs.) torque. (5) Lower vehicle.
KNUCKLE (FRONT SUSPENSION)
The front suspension knuckle (Fig. 1) provides for
steering control of the vehicle. Supports the brake
caliper and absorbs the loads exerted during vehicle
braking. It also supports the front (driving) hub and
bearing and stub axle assembly. The front suspension knuckle also provides the abil-
ity to align the front wheels of the vehicle. This is done
by allowing for front wheel camber adjustment and the
ability for front tire Toe adjustments The front suspension knuckle is not a serviceable
component. Do not attempt to straighten or repair the
front suspension knuckle in any way. Service repair or replacement of the front (drive) hub
and bearing, can be done with the front suspension
knuckle remaining on the vehicle.
REMOVAL
(1) Remove the cotter pin, hub nut lock and spring
washer from the front axle (Fig. 2). (2) Loosen hub nut while the vehicle is on the floor
with the brakes applied (Fig. 3). The hub and drive-
shaft are splined together through the knuckle
