Chrysler Le Baron, Dodge Dynasty, Plymouth Acclaim. Manual — part 78
(a) Severe deterioration of rubber isolator; re-
tainers for cracks and distortion and bond failure of
retainers and rubber isolators.
(b) Bearings for binding.
(c) Shock Absorber for flat spots over full stroke
also see, Shock Absorbers, (strut damper).
ASSEMBLE (STRUT DAMPER)
(1) Mount the strut assembly in a vertical position.
(2) Place the compressed spring onto the strut as-
sembly, so the end of the coil is seated in the seat re-
cess in lower spring mount (Fig. 9).
(3) Install the dust shield, isolator (if so equipped)
jounce bumper, spacer (as required), and spring seat
onto the top of the strut shaft (Fig. 8).
(4) Position top spring seat alignment tab correctly
with respect to bottom bracket (Fig. 9).
(5) Install the rebound retainer and shaft nut (Fig.
8).
(6) Tighten the strut shaft nut using, Strut Rod
Socket And Holder, Special Tool L-4558. Torque strut
shaft nut to 75 N
Im (55 ft. lbs.) plus 1/4 turn (Fig. 10).
WARNING: THIS STEP MUST BE DONE BEFORE
SPRING COMPRESSOR, SPECIAL TOOL C-4838 IS
RELEASED FROM THE COIL SPRING.
(7) Verify coil spring is aligned correctly with respect
to bottom bracket (Fig. 9).
(8) Release Spring Compressor Tool C-4838.
SUSPENSION COIL SPRINGS
Springs are rated separately for each side of vehicle
depending on optional equipment and type of service.
During service procedures where both springs are
removed, mark springs (Chalk, Tape, etc.) (Fig. 11) to
ensure installation in original position. If the coils
springs require replacement. Be sure that the
springs needing replacement, are replaced with
springs meeting the correct load rating for the
vehicle and its specific options.

moval or installation of a coil spring with Spring

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.

Inspect lower control arm for distortion. Check
bushings for severe deterioration.
INSTALLATION (ASSEMBLY)
(1) Position the lower control arm into the cross-
member. Install front and rear pivot bushing to
crossmember attaching bolts. Then loosely assemble
nuts to bolts (Fig. 2).
(2) Install ball joint stud into steering knuckle and
install clamp bolt (Fig. 1). Tighten clamp bolt to 145
N
Im (105 ft. lbs.).
(3) Position sway bar and bushings against the
lower control arms. Install sway bar to control arm
retainers. Install retainer bolts and tighten to 70
N
Im (50 ft. lbs.).
(4) Lower vehicle so the suspension is supporting
vehicles weight (control arm at design height).
Tighten the lower control arm to crossmember at-
taching bolts to 169 N
Im (125 ft. lbs.) torque.
LOWER CONTROL ARM PIVOT BUSHINGS
When performing the replacement procedure on the
lower control arm pivot bushings, the following se-
quence must be followed. When removing the pivot
bushings from the lower control arm, the large bush-
ing must be removed first then the small bushing.
When installing the pivot bushings into the lower
control arm, the small bushing must be installed
first then the large bushing. This sequence must be
used when removal and replacement of bushings is
done using Bushing Remover/Installer, Special Tool
6602.
LARGE BUSHING
REMOVE
(1) Position and clamp lower control arm in a vise.
(2) Assemble the washer, thrust bearing and large
bushing disk, Special tool 6602-5 onto the threaded
rod from Bushing Remover/Installer, Special Tool
6602 (Fig. 3).
(3) Install the tools assembled in step 2 above into
the large bushing of the lower control arm (Fig. 4).
Then assemble the remaining Special Tools, Cup
6602-2, thrust bearing, washer and long nut onto the
threaded rod (Fig. 4) from Bushing Remover/In-
staller, Special Tool 6602.
(4) Hold the long nut stationary. Using a deep
socket turn the long threaded rod until the large
pivot bushing is pushed out of the lower control arm.
SMALL BUSHING
REMOVE
(1) Remove the special tools from the lower control
arm that were used for the removal of the large pivot
bushing.
(2) Remove the large Bushing Disc, Special Tool
6602-5 from the threaded rod. Leave the thrust bear-
ing and washer on the threaded rod. Install the small
Bushing Disc, Special Tool 6602-3 on the threaded
rod and against thrust bearing (Fig. 5).

staller cone and new bushing using Mopar
t, Silicone
Spray Lube or equivalent.
(4) Hold the threaded rod stationary and turn the
long nut until the small pivot bushing is fully in-
stalled into the lower control arm. Be sure that the
flanges of the bushing are fully expanded around the
control arm bushing holes.
