Lower Ball JointNJSU0019S02Check ball joint for play. Replace transverse link assembly if
any of the following cases occur. Ball stud is worn, play in axial
direction is excessive or joint is hard to swing.
Before checking, turn ball joint at least 10 revolutions so that
ball joint is properly broken in.

Precautions
PRECAUTIONSNJSU0024When installing each rubber part, final tightening must be
carried out under unladen condition* with tires on ground.
Oil will shorten the life of rubber bushes. Be sure to wipe
off any spilled oil.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
Use flare nut wrench when removing or installing brake
tubes.
After installing removed suspension parts, check wheel
alignment.
Do not jack up at the trailing arm and lateral link.
Always torque brake lines when installing.
Lock nuts are unreusable parts; always use new ones.
When replacing, do not wipe the oil off of the new lock nut
before tightening.

REAR SUSPENSION PARTSNJSU0029Check axle and suspension parts for excessive play, wear or dam-
age.
Shake each rear wheel to check for excessive play.

Retighten all nuts and bolts to the specified torque.
Tightening torque:
Refer to “REAR SUSPENSION”, SU-17.

Check shock absorber for oil leakage or other damage.
Check wheelarch height. Refer to “On-vehicle Service”,
“FRONT SUSPENSION PARTS”, SU-6.
REAR WHEEL ALIGNMENTNJSU0030Before checking rear wheel alignment, be sure to make a prelimi-
nary inspection (Unladen*).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand
tools and mats in designated positions.
SFA975B
Preliminary InspectionNJSU0030S011. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage.
If deformed, remove wheel and check wheel runout.
a. Remove tire from wheel and mount wheel on a tire balance
machine.
b. Set dial indicator as shown in the illustration.
Wheel runout (Dial indicator value):
Refer to SDS, SU-15.
3. Check front wheel bearings for looseness.

4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that front shock absorbers work properly.
7. Check vehicle posture (Unladen).

Refer to SDS, SU-25.
If the camber is not within specification, inspect and replace
any damaged or worn rear suspension parts.

To e - i nNJSU0030S03Toe-in is preset at factory and cannot be adjusted.
Measure toe-in using following procedure. If out of
specification, inspect and replace any damaged or worn rear
suspension parts.
WARNING:
Perform following procedure always on a flat surface.
Make sure that no person is in front of the vehicle before
pushing it.
1. Bounce rear of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both tires at
the same height of hub center. This mark is a measuring point.
4. Measure distance “A” (rear side).
5. Push the vehicle slowly ahead to rotate the wheels 180
degrees (1/2 turn).
If the wheels have rotated more than 180 degrees (1/2 turn), try
the above procedure again from the beginning. Never push
vehicle backward.
6. Measure distance “B” (front side).
Total toe-in: A − B
Refer to SDS, SU-25.

REMOVALNJSU0031S01CAUTION:
Before removing the rear suspension assembly, disconnect
the ABS wheel sensor from the assembly. Failure to do so may
result in damage to the sensor wires and the sensor becom-
ing inoperative.
Remove suspension assembly.
1. Disconnect parking brake cable from caliper and remove brake
caliper and rotor.
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.
2. 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).
3. Lower transmission jack, and remove suspension.
4. Remove strut securing nuts (upper side). Then pull out strut
assembly.
SRA697A
INSTALLATIONNJSU0031S02Install suspension assembly.
CAUTION:
Refill with new brake fluid “DOT 4”.
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 caliper and rotor, then connect parking brake
cable to caliper.
6. Install ABS wheel sensor.

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.
