TOWING RECOMMENDATIONS
WARNING: DO NOT ALLOW TOWING ATTACH-
MENT DEVICES TO CONTACT THE FUEL TANK OR
LINES, FUEL LEAK CAN RESULT. DO NOT LIFT OR
TOW VEHICLE BY FRONT OR REAR BUMPER, OR
BUMPER ENERGY ABSORBER UNITS. DO NOT
VENTURE UNDER A LIFTED VEHICLE IF NOT SUP-
PORTED PROPERLY ON SAFETY STANDS. DO NOT
ALLOW PASSENGERS TO RIDE IN A TOWED VEHI-
CLE. USE A SAFETY CHAIN THAT IS INDEPENDENT
FROM THE TOWING ATTACHMENT DEVICE.
CAUTION: Do not damage brake lines, exhaust
system, shock absorbers, sway bars, or any other
under vehicle components when attaching towing
device to vehicle. Do not attach towing device to
front or rear suspension components. Do not
secure vehicle to towing device by the use of front
or rear suspension or steering components.
Remove or secure loose or protruding objects from
a damaged vehicle before towing. Refer to state and
local rules and regulations before towing a vehicle.
Do not allow weight of towed vehicle to bear on
lower fascia, air dams, or spoilers.
RECOMMENDED TOWING EQUIPMENT
To avoid damage to bumper fascia and air dams
use of a wheel lift or flat bed towing device (Fig. 2) is
recommended. When using a wheel lift towing device,
be sure the unlifted end of disabled vehicle has at
least 100 mm (4 in.) ground clearance. If minimum
ground clearance cannot be reached, use a towing
dolly. If a flat bed device is used, the approach angle
should not exceed 15 degrees.
GROUND CLEARANCE
CAUTION: If vehicle is towed with wheels
removed, install lug nuts to retain brake drums or
rotors.
A towed vehicle should be raised until lifted wheels
are a minimum 100 mm (4 in) from the ground. Be
sure there is adequate ground clearance at the oppo-
site end of the vehicle, especially when towing overrough terrain or steep rises in the road. If necessary,
remove the wheels from the lifted end of the vehicle
and lower the vehicle closer to the ground, to
increase the ground clearance at the opposite end of
the vehicle. Install lug nuts on wheel attaching studs
to retain brake drums or rotors.
LOCKED VEHICLE TOWING
When a locked vehicle must be towed with the
front wheels on the ground, use a towing dolly or flat
bed hauler.
FLAT TOWING WITH TOW BAR
²3-speed automatic transaxle vehicles can be flat
towed at speeds not to exceed 40 km/h (25 mph) for
not more than 25 km (15 miles). The steering column
must be unlocked and gear selector in neutral.
²5-speed manual transaxle vehicles can be flat
towed at any legal highway speed for extended dis-
tances. The gear selector must be in the neutral posi-
tion.
TOWINGÐFRONT WHEEL LIFT
Chrysler Corporation recommends that a vehicle be
towed with the front end lifted, whenever possible.
TOWINGÐREAR WHEEL LIFT
If a vehicle cannot be towed with the front wheels
lifted, the rear wheels can be lifted provided the fol-
lowing guide lines are observed.
CAUTION: Do not use steering column lock to
secure steering wheel during towing operation.
²Unlock steering column and secure steering
wheel in straight ahead position with a clamp device
designed for towing.
²Verify that front drive line and steering compo-
nents are in good condition.
²5-speed manual transaxle vehicles can be towed
at any legal highway speed for extended distances.
The gear selector must be in the neutral position.
²3-speed automatic transaxle vehicles can be
towed at speeds not to exceed 40 km/h (25 mph) for

of the service manual.
BALL JOINT ASSEMBLY
With the weight of the vehicle resting on the road
wheels. Grasp the grease fitting as shown in (Fig. 11)
and with no mechanical assistance or added force
attempt to move the grease fitting.
If the ball joint is worn the grease fitting will move
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/BEARING
The hub bearing is designed for the life of the vehi-
cle and requires no type of periodic maintenance. The
following procedure may be used for diagnosing the
condition of the hub bearing.
With the wheel, disc brake caliper, and brake rotor
removed, rotate the wheel hub. Any roughness or
resistance to rotation may indicate dirt intrusion or a
failed hub bearing. If the hub bearing exhibits any of
these conditions during diagnosis, the hub bearing
will require replacement, the bearing is not service-
able.
Damaged bearing seals and the resulting excessive
grease loss may also require bearing replacement.
Moderate grease weapage from the hub bearing is
considered normal and should not require replace-
ment of the hub bearing.

DESCRIPTION AND OPERATION
FRONT DISC BRAKES
The front disc brakes (Fig. 1) and (Fig. 2) consists
of the following components:
²The driving hub
²Braking disc (rotor)
²Caliper assembly - single piston, floating type
²Brake shoes and linings
The double pin calipers are mounted directly to the
steering knuckles and use no adapter. The caliper ismounted to the steering knuckle using bushings,
sleeves and 2 guide pin bolts which thread directly
into bosses on the steering knuckle (Fig. 2) and (Fig.
3).
Two machined abutments on the steering knuckle
position the caliper. The guide pin bolts, sleeves and
bushings control the side to side movement of the
caliper. The piston seal is designed to pull the piston
back into the bore of the caliper when the brake
pedal is released. This maintains the proper brake
shoe to rotor clearance (Fig. 4).
