REAR SUSPENSION
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 replace-
ment part of lesser quality or substitute design. Torque values must be used as specified during reas-
sembly 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.

3E-2 REAR SUSPENSION
GENERAL DESCRIPTION
Rear suspension is 5 link type of rigid axle which consists of coil springs, rear axle, shock absorbers, upper rods,
lower rods and lateral rod.
The lower rod and upper rod are connected with the axle and body by using bushes so that axle moves up and
down with bushes as their supporting points.
The shock absorber is installed between the body and axle to absorb up-and-down movement of the vehicle body.

DIAGNOSIS
DIAGNOSIS TABLE
Refer to SECTION 3.
SHOCK ABSORBER CHECK

Inspect for deformation or damage.

Inspect bushings for wear or damage.

Inspect for evidence of oil leakage.
Replace any defective part.
WARNING:
When handling rear shock absorber in which high-pressure
gas is sealed, make sure to observe the following precau-
tions.
1) Don't disassemble it.
2) Don't put it into the fire.
3) Don't store it where it gets hot.
4) 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.
5) The gas itself is harmless but it may issue out of the hole
together with chips generated by the drill. Therefore, be
sure to wear goggle.
LOWER ROD, UPPER ROD, LATERAL ROD
CHECK
Inspect for cracks, deformation or damage.
Replace any defective part.
Inspect each bush for wear and breakage. If found defective, re-
place.
AXLE HOUSING AND COIL SPRING CHECK
Inspect for cracks, deformation or damage.
Inspect for evidence of oil leakage at axle housing.
If any, replace defective part.

REAR SUSPENSION FASTENERS
Check each bolt and nut fastening suspension parts for tightness.
Tighten loose one, if any, to specified torque, referring to ªTIGHT-
ENING TORQUE SPECIFICATIONSº of this section.
BEARING RETAINER AND AXLE SHAFT
INNER 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.
WHEEL DISC, NUT & 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 retighten to specification
as necessary.
Tightening Torque
(a): 100 N
.m (10.0 kg-m, 72.5 lb-ft)

Check wheel bearings for wear. When measuring thrust play, ap-
ply a dial gauge to axle shaft center after removing wheel center
cap from wheel.
Thrust play limit
Rear0.8 mm (0.03 in.)
When measurement exceeds limit, replace bearing.

By rotating wheel actually, check wheel bearing for noise and
smooth rotation. If it is defective, replace bearing.

ON-VEHICLE SERVICE
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
1) Hoist vehicle and remove rear wheel.
2) Support rear axle housing by using floor jack to prevent it from
lowering.
3) Remove lock nut (if equipped) and absorber nut.
4) Remove lower mounting bolt.
5) Remove shock absorber.
INSTALLATION
1) Install shock absorber. Refer to figure for proper installing direc-
tion of lower mounting bolt.
2) Remove floor jack.
3) Lower hoist.
4) Tighten nuts to specified torque.
NOTE:

Tighten lower nut with vehicle off hoist and in non-loaded
condition.
