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.

CamberNJSU0030S02Camber is preset at factory and cannot be adjusted.
Camber:
Refer to SDS, SU-25.
+If the camber is not within specification, inspect and replace
any damaged or worn rear suspension parts.

Toe-inNJSU0030S03Toe-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 ªAº (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 ªBº (front side).

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.
SRA697A
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.
: 15 - 18 N´m (1.5 - 1.8 kg-m, 11 - 13 ft-lb)
6. Install ABS wheel sensor.
