The rear suspension assembly must be free of worn, loose or
damaged parts prior to measurement of rear wheel alignment.

Standard value
Toe . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 mm in-3 mm out
Camber . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40’

NOTE
The rear wheel alignment is set at the factory and cannot be
adjusted. If toe or camber is not within the standard value,
replace the bent or damaged parts.




WHEEL BEARING STARTING FORCE
INSPECTION
1. Remove the rear wheels.
2. Release the parking brake.
3. Measure the hub and drum starting force.
       Service limit                                             22 N (2.2 kg, 4.9 Ibs.) or less

4. If the hub and drum starting force exceeds the limit, remove the
   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 the
   bearings.

       NOTE
       There should be no axial clearance for hub and bearing.

   the rear suspension arm from the body as an assembly.




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.

   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 on the
   fixtures and suspension arms for reference during reassembly.
2. Loosen the nuts at both ends of the suspension arm to remove
   the fixtures and rubber bushings.




3. Before the rear suspension on cars with a rear stabilizer bar is
   disassembed, put aligning marks on each end of the stabilizer
   bar in alignment with the punch mark on the stabilizer bar
   bracket.
   Then, while the rear suspension is separated into the right and
   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 arm to 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 left
   suspension arm.




REASSEMBLY
1. Apply the specified grease to the inside of the left suspension.
55-10                                          REAR SUSPENSION

2. Using special tools (09555-21100, 09555-21000), drive bush-
   ings B and A, in that order, into the suspension arm.

   CAUTION
   1) 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 suspension arm.




3. When replacing the dust cover, insert a new one up to the
   center position (stopper) of the right suspension arm.
4. After applying grease to the surface of the right suspension
   arm, install the rubber stopper.




5. Slowly push the right and left suspension arms together. Wipe
   away the surplus grease. Align the marks on the stabilizer bar
   and the stabilizer bar bracket.
6. Install the rubber bushings, fixtures and washers.




7. After aligning the fixtures with the suspension arms according
   to the alignment marks, loosely tighten the nuts.
   CAUTION
   1) Install the washers and fixtures in the correct direction
      and position as shown.
   2) Tighten the nut to specification with the vehicle low-
      ered to the floor.
                                                REAR SUSPENSION    55-11

8. Pack grease in the dust cover and lips, and secure the dust
   cover with the clamp.




INSTALLATION
1. Tighten the fixture attaching bolts to the specified torque.
2. Install the coil springs.




3. Loosely install the shock absorbers.
    CAUTION

55-14                                               REAR AXLE HUB

INSTALLATION
1. Before installing the rear hub assembly, inspect the rear wheel
   bearing nut using the following method to determine whether it
   is reusable or not.
   1) Screw in the rear wheel bearing nut on the spindle untill the
       gap shown in the illustration is achieved.
   2) Measure the torque required to rotate the rear wheel
       bearing nut while backing it off (turning it counter-clock
       wise).
        Limit : 5.5 Nm (48 ft.lbs.)
    3) If the measured torque is less than the limit, replace the rear
       wheel bearing nut with a new one.

2. Install and tighten the self-locking nut to the specified torque.
   Check the wheel bearing for end play and starting force. (Refer
   to Page 55-6)
3. After filling the hubcap with multipurpose grease, install the hub
   cap.
