REMOVALNJSU0031S01CAUTION:
+Before removing the rear suspension assembly, discon-
nect the ABS wheel sensor from the assembly. Failure to
do so may result in damage to the sensor wires and the
sensor becoming inoperative.
+Remove suspension assembly.
1. Disconnect brake hydraulic lines and parking brake cable at
toggle lever. (Models with drum brakes.)
+Drain brake fluid before disconnecting brake lines.
2. Disconnect parking brake cable from caliper and remove brake
caliper and rotor. (Models with disc brakes.)
Suspend caliper assembly with wire so as not to stretch
brake hose.
Be careful not to depress brake pedal, or piston will pop
out.
Make sure brake hose is not twisted.
3. Using a transmission jack, raise torsion beam a little, and
remove nuts and bolts from the trailing arm, shock absorber
assembly (lower side) and lateral link (Body side).
4. Lower transmission jack, and remove suspension.
5. Remove strut securing nuts (upper side). Then pull out strut
assembly.

INSTALLATIONNJSU0031S02+Install suspension assembly.
CAUTION:
Refill with new brake fluid ªDOT 4º.
Never reuse drained brake fluid.
1. Attach torsion beam, at trailing arm and lateral link, to vehicle.
Do not tighten bolts at this time.
SRA698A
2. Using a transmission jack, place lateral link and control rod
horizontally against torsion beam. Tighten lateral link on
vehicle.
3. Attach shock absorber assembly to vehicle. Then tighten the
lower side of shock absorber assembly.
4. Lower torsion beam to fully extended position. Remove trans-
mission jack and tighten torsion beam, at trailing arm, to speci-
fied torque. Refer to SU-20.
5. Install brake hydraulic lines and tighten flare nuts.

Do not remove piston rod lock nut at this time.
2. Compress spring with Tool so that the shock absorber upper
spring seat can be turned by hand.
WARNING:
Make sure that the pawls of the two spring compressors are
firmly hooked on the spring. The spring compressors must be
tightened alternately so as not to tilt the spring.
3. Remove piston rod lock nut.
INSPECTIONNJSU0034Shock Absorber AssemblyNJSU0034S01+Check for smooth operation through a full stroke, both com-
pression and extension.
+Check for oil leakage on welded or gland packing portions.
+Check piston rod for cracks, deformation or other damage.
Replace if necessary.
Upper Rubber Seat and BushingNJSU0034S02Check rubber parts for deterioration or cracks.
Replace if necessary.
Coil SpringNJSU0034S03Check for cracks, deformation or other damage. Replace if
necessary.

+When installing coil spring, be careful not to reverse top and
bottom direction. (Top end is flat.)
+When installing coil spring on shock absorber, it must be posi-
tioned as shown in figure at left.
CAUTION:
Do not reuse piston rod lock nut.

Checking Neutral Position on Steering WheelNJST0008PRE-CHECKINGNJST0008S01+Make sure that wheel alignment is correct.
Wheel alignment:
Refer to SU-14, SDS.
+Verify that the steering gear is centered before removing the
steering wheel.
CHECKINGNJST0008S021. Check that the steering wheel is in the neutral position when
driving straight ahead.
2. If it is not in the neutral position, remove the steering wheel and
reinstall it correctly.
3. If the neutral position is between two teeth, loosen tie-rod lock
nuts. Turn the tie-rods by the same amount in opposite direc-
tions on both left and right sides.
SMA127
Front Wheel Turning AngleNJST00091. Rotate steering wheel all the way right and left; measure turn-
ing angle.
Turning angle of full turns:
Refer to SU-14, SDS.
2. If it is not within specification, check rack stroke.
Rack stroke ªSº:

Checking Gear Housing MovementNJST00101. Check the movement of steering gear housing during station-
ary steering on a dry paved surface.
+Apply a force of 49 N (5 kg, 11 lb) to steering wheel to check
the gear housing movement.
Turn off ignition key while checking.
Movement of gear housing:
