WARNING:
When hoisting vehicle, be sure to select the lifting point suitable for the service work referring to Sec-
tion 0A.
NOTE:
All suspension fasteners are an important attaching part in that it could affect the performance of
vital parts and systems, and/or could result in major repair expense. They must be replaced with
one of the same part number or with an equivalent part if replacement becomes necessary. Do not
use a replacement part of lesser quality or substitute design. Torque values must be used as speci-
fied during reassembly to assure proper retention of this part.
Never attempt to heat, quench or straighten any suspension part. Replace it with a new part, or
damage to the part may result.

Diagnosis
Diagnosis Table
Refer to “Diagnosis Table” in Section 3.
Rear Shock Absorber Check
Inspect for deformation or damage.
Inspect bushings for wear or damage.
Inspect for evidence of oil leakage.
Replace any defective part.
Trailing Arm, Lateral Rod, Axle Housing and
Coil Spring Check
Inspect for cracks, deformation or damage.
Replace any defective part.
Trailing Arm and Lateral Rod Bush Check
Inspect for wear and breakage. If found defective, replace.WARNING:
When handling rear shock absorber in which high-pres-
sure gas is sealed, make sure to observe the following
precautions.
Don’t disassemble it.
Don’t put it into the fire.
Don’t store it where it gets hot.
Before disposing it, be sure to drill a hole in it where
shown by an arrow in the figure and let gas and oil out.
Lay it down sideways for this work.
The gas itself is harmless but it may issue out of the
hole together with chips generated by the drill. There-
fore, be sure to wear goggle.
A : Drill hole with approximately 3 mm (0.12 in.) diameter.

Rear Suspension Fasteners
Check each bolt and nut fastening suspension parts for tightness.
Tighten loose one, if any, to specified torque, referring to “Tighten-
ing Torque Specifications” of this section.
Bearing Retainer and Axle Shaft Oil Seal
Check
When brake drum has been removed, check inside of brake
drum for gear oil leakage.
Also, check backside of brake back plate for oil leakage.If oil
leakage is found, replace defective oil seal.
Whenever it is possible to check oil seal during disassembly,
check its lip for wear.
If oil leakage or worn lip is found, replace defective oil seal.
Bump Stopper and Spring Rubber Seat Check
Inspect for wear and breakage. If found defective, replace.
Wheel Disc, Nut and Bearing Check
Inspect each wheel disc for dents, distortion and cracks. A
disc in badly damaged condition must be replaced.
Check wheel hub nuts for tightness and, as necessary,
retighten to specification.
Tightening torque
Wheel nuts
(a) : 95 N·m (9.5 kg-m, 69.0 lb-ft)

Check wheel bearings for wear. When measuring thrust
play, apply a dial gauge to axle shaft center after removing
wheel center cap from wheel disc.
When measurement exceeds limit, replace bearing.
Rear wheel bearing thrust play limit
: 0.8 mm (0.03 in.)
By rotating wheel actually, check wheel bearing for noise and
smooth rotation. If it is defective, replace bearing.
On-Vehicle Service
Rear Shock Absorber
The shock absorber is non-adjustable, non-refillable, and cannot be disassembled. The only service the shock
absorber requires is replacement when it has lost its resistance, is damaged, or leaking fluid.
REMOVAL

2) Support rear axle housing (1) by using floor jack (2) to pre-
vent it from lowering.
WARNING:
When discarding shock absorber, be sure to refer to instructions in “Rear Shock Absorber Check” in
this section for proper procedure as it is gas sealed type.
