INSPECTION
1. INSPECT A.D.D. ACTUATOR
(a) Disconnect the actuator connector.
(b) Measure the resistance between terminals 2 and 6.
Standard resistance: 0.3 ± 100 W
(c) Measure the resistance between terminal 2 or 6 and body
ground.
Standard resistance: More than 0.5 MW
If the resistance value is not as specified, replace the actuator
assembly.
2. INSPECT A.D.D. ACTUATOR OPERATION
Apply battery positive voltage between terminals 2 and 6, and
check the actuator operation by sound, A.D.D. status and conti-
nuity between terminals 3 and 4.

If the operation is not as specified, replace the actuator assem-
bly.
3. INSPECT LIMIT SWITCH CONTINUITY
(a) Connect the actuator connector.
(b) Push the 2WD/4HI switch and check that the 4WD indica-
tor light comes on after it is blinking.
(c) Check the A.D.D. actuator operation by sound.
(d) Disconnect the actuator connector.
(e) Check the continuity between each terminal, as shown in
the chart.

5. REMOVE A.D.D. ACTUATOR (See page SA±43)
6. INSPECT CLUTCH HUB AND CLUTCH SLEEVE
(a) Check the clutch hub and clutch sleeve for wear and dam-
age.
If necessary, replace them.
(b) Check that clutch sleeve slides smoothly on the clutch
hub.
7. MEASURE SLEEVE FORK AND CLUTCH SLEEVE
CLEARANCE
Using a feeler gauge, measure the clearance between the
sleeve fork and clutch sleeve.
Maximum clearance: 0.35 mm (0.0138 in.)
If the clearance exceeds the maximum, replace the fork or
sleeve.

SUSPENSION ARM
(a) Remove the shock absorber lower side set nut and wash-
er.
NOTICE:
Do not remove the bolt.
(b) Pry down the lower suspension arm to remove the bolt
and disconnect the shock absorber.
3. REMOVE SHOCK ABSORBER WITH COIL SPRING
Remove the 3 nuts and shock absorber with the coil spring.

DISASSEMBLY
REMOVE SUSPENSION SUPPORT AND COIL SPRING
(a) Using a spring compressor, compress the coil spring.
NOTICE:
Use a spring compressor with which compressive
force of 12,740 N (1,300 kgf, 2,860 lbf) or more can be
applied.
Make sure that the suspension support is free from
the coil spring.
Do not compress the coil spring more than neces-
sary.
Do not place yourself over the top of the shock ab-
sorber.
(b) Remove the suspension support center nut.
(c) Remove the 2 retainers, cushion, suspension support
and coil spring.

INSPECTION
INSPECT SHOCK ABSORBER
Compress and extend the shock absorber rod and check that
there is no abnormal resistance or unusual operation sounds.
If there is any abnormality, replace the shock absorber with a
new one.

DISPOSAL
1. FULLY EXTEND SHOCK ABSORBER ROD
2. DRILL HOLE TO DISCHARGE GAS FROM CYLINDER
Using a drill, make a hole in the cylinder as shown in the illustra-
tion to discharge the gas inside.
CAUTION:
The discharged gas is harmless, but be careful of chips
which may fly out when drilling.
