PrecautionsEES002JD
lWhen installing rubber parts, final tightening must be carried out under unladen condition* with
tires on ground.
*Fuel, radiator coolant, and engine oil are full. Spare tire, jack, hand tools, and mats are in their
designated positions. Oil will shorten the life of rubber bushings, so wipe off any spilled oil imme-
diately.
lLock nuts are not reusable. Always use new lock nuts for installation. New lock nuts are pre-oiled,
do not apply any additional lubrication.

CAUTION:
When installing the components with rubber bushings, the final tightening of the nuts and bolts must
be done with the vehicle in an unladen condition (the fuel, engine coolant, and engine oil full; the
spare tire, jack, hand tools and mats in their designated positions) with the tires on the ground.
On-Vehicle Inspection and ServiceEES002JH
lCheck the rear suspension parts for any excessive play, cracks, wear, and other damage.
lShake each rear wheel to check for any excessive play as
shown.
lTighten all of the nuts and bolts to the specified torque.
CAUTION:
When installing the components with rubber bushings, the
final tightening of the nuts and bolts must be done with the
vehicle in an unladen condition (the fuel, engine coolant,
and engine oil full; the spare tire, jack, hand tools and mats
in their designated positions) with the tires on the ground.
lCheck the shock absorbers for oil leaks, deformation, and other

REMOVAL
1. Support the rear final drive assembly with a suitable jack to relieve the tension from the rear leaf spring.
lThe axle weight should be supported, but there should be no compression in the rear leaf spring.
2. Remove the shock absorber lower nut and bolt.
3. Remove the four rear spring clip U-bolt nuts, then remove the
rear spring pad.
4. Remove the rear spring shackle and bushings.
5. Remove the rear leaf spring front nut and bolt.
6. Remove the rear leaf spring.

8. Tighten the rear spring shackle nuts, rear leaf spring front nut,
and shock absorber nuts to specification.
lWhen installing the components with rubber bushings, the
final nut tightening must be carried out under unladen* condi-
tions with the tires on level ground.

How to Handle BatteryEKS00MZ7
CAUTION:
lIf it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt
booster battery.
lAfter connecting battery cables, ensure that they are tightly clamped to battery terminals for good
contact.
lNever add distilled water through the hole used to check specific gravity.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharging a battery.
lThe battery surface (particularly its top) should always be kept
clean and dry.
lThe terminal connections should be clean and tight.
lAt every routine maintenance, check the electrolyte level.
This also applies to batteries designated as “low maintenance”
and “maintenance-free”.
lWhen the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal. (If the vehicle has
an extended storage switch, turn it off.)
lCheck the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep a
close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL
WARNING:
Do not allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, do not touch or rub your eyes until you have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.

CHARGING SYSTEM
CHARGING SYSTEM
PFP:00011
System DescriptionEKS00MZA
The alternator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times to alternator terminal 4 through:
l15A fuse (No. 30, located in the fuse and fusible link box).
Terminal 1 supplies power to charge the battery and operate the vehicle's electrical system. Output voltage is
controlled by the IC regulator at terminal 4 detecting the input voltage. The charging circuit is protected by the
140A fusible link (letter "A", located in the fuse and fusible link box) .
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied
l10A fuse [No. 14, located in the fuse block (J/B)]
lto combination meter terminal 16 for the charge warning lamp.
Ground is supplied With power and ground supplied
lto terminal 2 of the combination meter
lthrough terminal 3 of the alternator.
If the charge warning lamp illuminates with the engine running, a fault is indicated.
The charge warning lamp will illuminate. When the alternator is providing sufficient voltage with the engine
running, the ground is opened and the charge warning lamp will go off.
