Group 25, Emission Control Systems for proper ser-
vice procedures.
BATTERY
Inspect battery tray, hold down and terminal con-
nections when other under hood service is performed.
For proper diagnostic procedures refer to Group 8A,
Battery/Starting/Charging System Diagnostics. For
service and cleaning procedures refer to Group 8B,
Battery/Starter Service.
RUBBER AND PLASTIC COMPONENT INSPECTION
CAUTION: Plastic hoses or wire harness covers will
melt or deform when exposed to heat from exhaust
system or engine manifolds. Position plastic or rubber components away from
moving parts in engine compartment or under vehi-
cle, or damage will result. Do not allow rubber engine mounts or other com-
ponents to become oil contaminated, repair cause
of oil contamination and clean area. All rubber and plastic components should be in-
spected when engine compartment or under vehicle
service is performed. When evidence of deterioration
exists, replacement is required. To reduce deteriora-
tion of rubber components, Chrysler Corporation rec-
ommends Mopar Foamy Engine Degreaser or
equivalent be used to clean engine compartment of
oil and road grime.
EXHAUST SYSTEM ISOLATOR AND HANGER
The exhaust system should be inspected when un-
der vehicle service is performed. The exhaust system
should not make contact with under body, brake ca-
bles, brake/fuel lines, fuel tank or suspension compo-
nents. Slight cracking in rubber isolator or hanger is
acceptable. Severely cracked or broken rubber compo-
nents must be replaced. For proper service proce-
dures see Group 11, Exhaust System and Intake
Manifold.

should be above ADD mark. Add fluid only if level is
below ADD mark on dipstick when transaxle is
warm.The automatic transaxle does not require periodic
maintenance when used for general transportation. If
the vehicle is subjected to severe service conditions,
the automatic transaxle will require fluid/filter
change and band adjustments every 24 000 km
(15,000 miles). For additional information, refer to
Severe Service paragraph and Lubrication and Main-
tenance Schedules in General Information section of
this group. The fluid and filter should be changed
when water contamination is suspected. If fluid has
foamy or milky appearance, it is probably contami-
nated. If the fluid appears brown or dark and a foul
odor is apparent, the fluid is burned, transaxle re-
quires maintenance or service. A circular magnet lo-
cated in the transaxle pan, collects metallic particles
circulating in the oil. For proper diagnostic and ser-
vice procedures, refer to Group 21, Automatic Tran-
saxle.
SELECTING AUTOMATIC TRANSAXLE FLUID
Chrysler Corporation recommends Mopar ATF Plus
(automatic transmission fluid type 7176) be used to
add to or replace automatic transaxle fluid. If ATF
Plus is not available use Mopar Dexron II tAuto-
matic Transmission Fluid or equivalent.
DRIVE SHAFT CV AND TRIPOD JOINT BOOTS
The front drive shaft constant velocity and tripod
joint boots (Fig. 5) should be inspected when other
under vehicle service is performed. Inspect boots for
cracking, tears, leaks or other defects. If service re-
pair is required, refer to Group 2, Suspension.
FRONT WHEEL BEARINGS
The front wheel bearings are permanently sealed,
requiring no lubrication. For proper diagnostic and
service procedures refer to Group 2, Suspension.
TIRES
The tires should be inspected at every engine oil
change for proper inflation and condition. The tires
should be rotated at the distance intervals described
in the Lubrication and Maintenance Schedules of the
General Information section in this group. For tire
inflation specifications refer to the Owner's Manual.
A Tire Inflation sticker is located in the driver door
opening. For proper diagnostic procedures, see Group
22, Wheels and Tires.Fig. 2 3-speed Automatic Transaxle Fill hole

STEERING LINKAGE
INSPECTION
The steering linkage and steering gear should be in-
spected for wear, leaks or damage when other under ve-
hicle service is performed. The rack and pinion steering
gear end boots should not have excess oil or grease res-
idue on the outside surfaces or surrounding areas
(Fig.1). If boot is leaking, it should be repaired. For
proper service procedures, see Group 19, Steering.
The tie rod end seal should fit securely between the
steering knuckle and tie rod end (Fig.2). The steering
linkage should be lubricated at the time and distance
intervals described in the Lubrication and Mainte-
nance Schedules. Refer to General Information sec-
tion of this group.
TIE ROD END LUBRICATION
Lubricate the steering linkage with Mopar, Multi-
mileage Lube or equivalent. Using a wiping cloth,
clean grease and dirt from around grease fitting and
joint seal. Using a grease gun, fill tie rod end until
lubricant leaks from around the tie rod end side of
the seal (Fig.2). When lube operation is complete,
wipe off excess grease.
LOWER BALL JOINTS
INSPECTION
The front suspension lower ball joints should be in-
spected for wear, leaks or damage when other under ve- hicle service is performed. The ball joint seal should fit
securely between the steering knuckle and lower control
arm (Fig. 3). The ball joints should be lubricated at the
time and distance intervals described in the Lubrication
and Maintenance Schedules. Refer to the General Infor-
mation section of this group.
BALL JOINT LUBRICATION
CAUTION: Do not over fill ball joint with grease,
damage to seal can result.
Lubricate the ball joints with Mopar, Multi-mile-
age Lube or equivalent. Using a wiping cloth, clean
grease and dirt from around grease fitting and joint
seal. Using a grease gun, fill ball joint until seal
starts to swell (Fig. 3). When lube operation is com-
plete, wipe off excess grease.
POWER STEERING
The power steering fluid level should be inspected
when other under hood service is performed. If the
fluid level is low and system is not leaking, use Mo-
par, Power Steering Fluid or equivalent. The power
steering system should be inspected for leaks when
other under vehicle service is performed. For proper
service procedures, refer to Group 19, Steering.Fig. 1 Inspect Steering Linkage

GENERAL INFORMATION
Throughout this group, references may be made to
a particular vehicle by letter or number designation.
A chart showing the breakdown of these designations
is included in the Introduction section at the front of
this Service Manual. An independent MacPherson Type front suspension
is used on these vehicles. Vertical shock absorbing
struts attach to the upper fender reinforcement and the steering knuckle to provide upper steering
knuckle position. Lower control arms are attached
inboard to a crossmember and outboard to the steer-
ing knuckle through a ball joint to provide lower
steering knuckle position. During steering maneu-
vers, the strut (through a pivot bearing in the upper
retainer) and the steering knuckle turn as an assem-
bly (Fig. 1).

Compressor, Special Tool C-4838. It is required
that five coils be captured within the jaws of the
tool (Fig. 11).
SPRING RETAINER UPPER
Ensure that upper spring retainer is positioned
properly, see; step (4), Assemble (Strut Damper).
SPRING SEAT LOWER
During assembly of the coil spring to strut damper.
Ensure that lower coil spring end is seated in strut
damper spring seat recess refer to (Fig. 9) in assem-
ble (Strut Damper) section.
SHOCK ABSORBERS (Strut Damper)
INSPECTION
Inspect for evidence of fluid leaking from around
the strut assembly shaft seal at the upper end of the
reservoir. (Actual leakage will be a stream of fluid
running down the side and dripping off lower end of
unit. A slight amount of seepage around the strut
rod is not unusual and does not affect performance.
LOWER CONTROL ARM
The lower control arm if damaged, is serviced only
as a complete component. 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, and both pivot
bushings. The service procedure to replace these com-
ponents is detailed in the specific component sections
of this group.
REMOVAL (ASSEMBLY)
(1) Raise vehicle. See Hoisting in Lubrication,
Group 0 of this service manual. (2) Remove the ball joint stud to steering knuckle
clamp nut and bolt (Fig. 1). (3) Remove the sway bar to lower control arm re-
tainer on both sides of the vehicle (Fig. 2). Then ro-
tate the sway bar down away from the lower control
arms. (4) Separate the steering knuckle from the ball
joint stud (Fig. 1). (5) Remove the front and rear control arm pivot
bushing to crossmember attaching nuts and bolts
(Fig. 2). Then remove the lower control arm from the
crossmember.
CAUTION: Pulling steering knuckle out from vehicle
after releasing from ball joint can separate inner
C/V joint. See Driveshafts.
