INSTALLATION
Install removed parts in reverse order of removal, noting the follow-
ing.
1) Place rear axle housing on floor jack. Then install upper / lower
rod rear mounting bolts (right & left) in proper direction as shown
(refer to UPPER ROD INSTALLATION for upper rod bolts). At
this time, mount nuts but don't tighten them.
2) Install coil spring (right & left) on spring seat of axle housing and
raise axle housing.
NOTE:
When seating coil spring, mate spring end with stepped
part of rear axle spring seat as shown.
3) Install lateral rod to rear axle housing.
4) Install lower part of shock absorber to right and left sides of axle
housing and install bolts in proper direction as shown in figure.
At this time, mount nuts but don't tighten them.
5) Clean mating surfaces of axle housing and differential carrier
and apply sealant to housing side.
ªAº: Sealant 99000-31110
6) Install differential carrier assembly to axle housing and tighten
carrier nuts to specified torque.

4WD Control System Diagnostic Flow Table
Before performing the trouble diagnosis, check that the transfer and front differential are in good condition and
there is no air leakage from air hoses and the actuator. Refer to ªON-VEHICLE SERVICEº in this section for air
leakage.
[NOTES ON SYSTEM CIRCUIT INSPECTION]
Be sure to read ªPrecautions for Electrical Circuit Serviceº in Section 0A before circuit inspection and observe
what is written there.
For system circuit, refer to the figure of ªGENERAL DESCRIPTIONº in this section.
For terminal arrangement, refer to ª4WD Control Circuit Inspectionº in this section.

INSPECTION
4WD Control System
1) Install special tool to air hose connecting between air pump as-
sembly and differential (actuator) as shown in figure. Tighten ad-
justing screw of special tool as far as it stops. Close air check
side opening by using fuel hose as blind plug.
Special Tool
(A): 09918-18110
(B): 09367-04002
NOTE:
Use care not to bend any part of hose.
2) Turn ON ignition switch and shift transfer lever from 2H to 4H
range.
3) Check that motor starts running (a sound can be heard) within
1 second and it stops when gauge of special tool indicates speci-
fied pressure value.
Check also for air leakage.
Pressure specification:
30.0 ± 45.0 kPa (0.30 ± 0.45 kg / cm
2, 4.25 ± 6.40 psi)
4) Check that pressure value indicated on gauge of special tool
drops as soon as transfer lever is shifted to 2H position.
5) Start motor by shifting transfer lever to 4H position again. Loos-
en adjusting screw to lower pressure value on gauge. Motor
should start to run again and stop in about 4 seconds.
6) With the adjusting screw of special tool loosened, shift transfer
shift lever to N or 2H position and then 4L or 4H position.
Pump motor should stop about 10 seconds after motor starts to
run.
