1999 DODGE NEON suspension

Inspect the tension strut for signs of contact with
the ground or road debris which has bent or caused
other damage to the tension strut. If the tension
strut is bent or damaged the tension strut will
require replacement.Do not attempt to repair or
straighten a tension strut.
STABILIZER BAR AND BUSHINGS
Inspect the stabilizer bar for damage or bending.
Inspect for broken or distorted stabilizer bar bush-
ings, bushing retainers, and worn or damaged stabi-
lizer bar to strut attaching links. If stabiizer bar to
rear frame rail bushing replacement is required,
bushings can be removed from sway bar by opening
slit and peeling bushing off sway bar.
STABILIZER BAR ATTACHING LINKS
Inspect the bushings and sleeves in the stabilizer
bar attaching links for damage or deterioration.
Inspect the stabilizer bar attaching link to ensure it
is not bent or broken. If any of these conditions are
present when inspecting the attaching links, replace-
ment of the attaching link is required.
SERVICE PROCEDURES
REAR WHEEL ALIGNMENT

dures in the Wheel Alignment Check And Adjustment
section in this group of the service manual for the
required rear wheel Toe setting procedure.
REMOVAL AND INSTALLATION
STRUT ASSEMBLY
REMOVE
(1) Raise vehicle on jackstands or centered on a
frame contact type hoist. See Hoisting in the Lubri-
cation and Maintenance section of this manual, for
the required lifting procedure to be used for this
vehicle.
(2) Remove the rear wheel and tire assembly from
the vehicle.
(3) Remove hydraulic flex hose bracket, from
bracket on rear strut assembly (Fig. 6). If vehicle is
equipped with Anti-Lock brakes, the wheel speed
sensor cable routing clip is also attached to the strut
assembly bracket.
(4) Support rear knuckle, suspension and brake
components of vehicle before removing clevis bracket
to knuckle attaching bolts.Do not let weight of
rear knuckle and assembled components hang
unsupported when strut is removed.CAUTION: The knuckle to strut assembly attaching
bolts are serrated and must not be turned during
removal. Remove nuts while holding bolts station-
ary in knuckle.
(5) Remove the 2 clevis bracket bolts (Fig. 7)
attaching strut assembly to rear knuckle.

tower. Then remove rubber dust shield (Fig. 8) from
top of strut tower, this will allow easier access to
upper strut mount attaching nuts.
(8) Loosen but do not remove the 4 upper strut
mount to strut tower attaching nuts (Fig. 9). Then
while supporting the strut assembly fully remove the
4 strut mount attaching nuts.
(9) Remove strut assembly from knuckle, by slid-
ing knuckle out of clevis bracket on strut assembly.
Then remove strut assembly from vehicle.
INSTALL
(1) Position strut assembly back into vehicle with
the 4 studs on strut mount assembly through holes
in strut tower of vehicle. Install the 4 strut mount to
body attaching nuts (Fig. 9) onto mount studs.
Torque the 4 strut mount to body attaching nuts to
34 N´m (300 in. lbs).(2) Install dust shield into hole on top of strut
tower (Fig. 8). Install carpeting back on top of rear
strut tower.
(3) Raise vehicle.
CAUTION: The knuckle to strut assembly attaching
bolts are serrated and must not be turned during
installation. Install and torque nuts while holding
bolts stationary in knuckle.

sequence until all nuts are torqued to half specifica-
tion. Then repeat tightening sequence to full speci-
fied torque of 135 N´m (100 ft. lbs.).

tions if required. Refer to Front And Rear Toe Setting
Procedure in the Wheel Alignment Check And
Adjustment section in this group of the service man-
ual for the required Toe setting procedure.
COIL SPRING
Coil 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. 10) to ensure installation in original posi-
tion. If the coils springs require replacement.Be
sure that the springs needing replacement, are
replaced with springs meeting the correct load
and spring rate for the vehicle.
NOTE: During service procedures requiring
removal or installation of a coil spring with Spring
Compressor, Special Tool C-4838. It is required that
the first full top and bottom coil of the coil spring
be captured by the jaws of spring compressor (Fig.
10).
Replacement of the coil spring requires removal of
the strut assembly from the vehicle, and the disas-
sembly of the strut. Refer to strut assembly in the
removal and installation section in this group of the
service manual for the required removal and replace-
ment procedure for the strut assembly. Then refer to
