Diagnosis
Diagnosis Table
For description not found in the table below, refer to “Diagnosis Table” in Section 3.
4WD CONTROL SYSTEM
4WD CONTROL SYSTEM DIAGNOSTIC FLOW TABLE
Before performing the trouble diagnosis, check that the air locking hub assemblies are in good condition and
there is no air leakage from vacuum hoses and vacuum pipe. Refer to “4WD Control System Check” in this sec-
tion for air leakage.
[NOTES ON SYSTEM CIRCUIT INSPECTION]
Be sure to read “Precautions for Electrical Circuit Service” in Section 0A before circuit inspection and
observe what is written there.
For system circuit, refer to the figure of “System Circuit” in this section. Condition Possible Cause Correction

Step Action Yes No
1 Check ground circuit.
1) Disconnect coupler from 4WD controller
with ignition switch OFF.
2) Check for proper connection to 4WD con-
troller at all terminals.
3) If OK, check continuity between A5 terminal
and body ground.
Is there continuity between A5 terminal and
body ground?Go to Step 2.“B” wire is open.
2 Check power circuit.
1) Disconnect coupler from 4WD controller.
2) Turn ignition switch ON.
3) Check voltage between A10 terminal and
ground.
Is it 10 – 14 V?Go to Step 3.“Y/R” circuit is open or
short.

Leading Arm Bushing / Lateral Rod Bushing
Check
Inspect for damage, wear or deterioration.
If defective, replace.
Kingpin / Kingpin Bearing Check
1) Inspect for wear or deterioration.
2) Inspect for crack, damage or deformation of kingpin.
If defective, replace.
Barfield Joint Check
To be checked on this joint is its axial play, which shows up when
a push-and-pull motion is given to live axle shaft and wheel spin-
dle held in both hands, as shown in figure. There should be no
play at all but a play of up to 1.5 mm (0.06 in.) is permissible. If
play exceeds service limit, replace it.
Axial play in barfield joint
Steering Knuckle Seal Check
The knuckle seal used at the spherical sliding joint between the
knuckle and the inner case accomplishes the additional purposes
of keeping out road dust and of acting as the damper for the
steering handwheel. As the wear of this seal advances, its damp-
ing effect decreases and thus make the front wheel develop a ten-
dency to “shimmy” not only that road dust begins to creep into the
sliding clearance to promote the wear of the spherical sliding sur-
faces.
Check the knuckle seal for wear or damage. If defective, replace
with new one.
Standard Service Limit
0 mm (no play) 1.5 mm (0.06 in.)

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.

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
1) Hoist vehicle.
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.
