SERVICE ADJUSTMENT PROCEDURE
REAR WHEEL ALIGNMENT
The rear suspension assembly must be free of worn, loose ordamaged parts prior to measurement of rear wheel alignment.
Standard valueToe . . . . . . . . . . . . . . . . . . . . . . . .Camber . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
NOTEThe rear wheel alignment is set at the factory and cannot beadjusted. If toe or camber is not within the standard value,replace the bent or damaged parts.
WHEEL BEARING END PLAY INSPECTION
1. Release the parking brake lever.2. Set the dial indicator as shown in the illustration.
Measure the end play while moving the hub or drum in andout.
Service limit . . . . . . . . . . . . . . . . . . . . . . 0.11 mm (0.0043 in.)
3. If the end play exceeds the limit, retighten the self-lockingnut and recheck the play.
4. If the end play is still beyond the limit, replace the bearing.
WHEEL BEARING STARTING TORQUEINSPECTION
1. Remove the rear wheels.2. Release the parking brake.3. Measure the hub and drum starting force.
Service limit 1.25 Nm (12.5 kg.cm, 10.8 Ib.in)21.8 N (2.18 kg, 4.81 Ibs.)
4. If the hub and drum starting force exceeds the limit, removethe hub cap, loosen the wheel bearing nut and retighten it,and recheck the hub and drum starting force.
5. If the hub starting force is still beyond the limit, replace thebearings.

6. Lower the jack. Remove the coil spring and temporarilyinstall the shock absorber to the suspension arm.
7. Disconnect the brake hose at the suspension arm andremove the rear suspension arm from the body as anassembly.
INSPECTION
1. Check the suspension arm for distortion or damage.2. Check the suspension shaft for distortion or damage.3. Check the dust cover for damage.4. Check the shock absorbers for malfunction, oil leakage or
noise.5. Check the coil springs for deterioration, cracks or damage.6. Check the spring seats and bump stoppers for damage.7. Check the stabilizer bar for damage.
DISASSEMBLY
1. Before the fixtures are removed, make alignment marks onthe fixtures and suspension arms for reference duringreassembly.

3. Before the rear suspension on cars with a rear stabilizer baris disassembled, put aligning marks on each end of thestabilizer bar in alignment with the punch mark on thestabilizer bar bracket.Then, while the rear suspension is separated into the rightand left arms, remove the stabilizer from the bracket.
4. Remove the dust cover clamp.5. Separate the suspension arm into the right and left arms.
Leave the dust cover attached to the right suspension armto protect the lip from damage.
6. Remove the rubber stopper from the right arm.
7. Using a flat-blade screwdriver, remove bushing A.

8. Using a hammer and drift, drive bushing B out of the leftsuspension arm.
REASSEMBLY
1. Apply the specified grease to the inside of the leftsuspension.
2. Using special tools (09555-21100, 09555-21000), drivebushings B and A, in that order, into the suspension arm.
CAUTION1) Apply grease to all outside surfaces of bushings B and
A.2) Drive bushing B in until the notch on the special tool
(09555-21000) reaches the end of the suspensionarm.

3. When replacing the dust cover, insert a new one up to thecenter position (stopper) of the right suspension arm.
4. After applying grease to the surface of the right suspensionarm, install the rubber stopper.
5. Slowly push the right and left suspension arms together.Wipe away the surplus grease. Align the marks on thestabilizer bar and the stabilizer bar bracket.
6. Install the rubber bushings, fixtures and washers.
7. After aligning the fixtures with the suspension armsaccording to the alignment marks, loosely tighten the nuts.
CAUTION1) Install the washers and fixtures in the correct direction
and position as shown.2) Tighten the nut to specification with the vehicle
lowered to the floor.
8. Pack grease in the dust cover and lips, and secure the dustcover with the clamp.
