A: INSPECTION
1. SUSPENSION BALL JOINT
1) Jack-up the vehicle until front wheels are off
ground.
2) Grasp the bottom of tire and move it in and out
along the shaft. If relative movement is observed
between the brake disc cover (A) and end of front
arm (D), ball joint (C) may be excessively worn.
3) Grasp the end of front arm and move it up and
down. Relative movement (A) between the housing
(D) and front arm (C) boss indicates ball joint (B)
may be excessively worn.
4) If relative movement is observed in the step 2),
3), remove and inspect the ball joint. If the free play
exceeds standard value, replace the ball joint.
5) Damage of dust seal
Visually inspect the ball joint dust seal. If it is dam-
aged, remove the front arm.
Arm.> Also, measure the free play of the ball joint.
(1) When looseness exceeds standard value,
replace the ball joint.
(2) If the dust seal is damaged, replace with a
new ball joint.
NOTE:
When the front arm ball joint has been removed or
replaced, check the toe-in of front wheel. If the front
wheel toe-in is not at specified value, adjust the
toe-in.
2. FRONT, REAR SUSPENSION BUSHING
Apply pressure with tire lever etc, and inspect the
bushing for wear or crack. Replace the bushings
and the arm assembly or link assembly if there is
wear or there are cracks.
3. WHEEL ARCH HEIGHT
1) Unload the cargo and set the vehicle in curb
weight (empty) condition.
2) Check the wheel arch height of the front and rear
suspensions to ensure that they are within speci-
fied values.
3) When the wheel arch height is out of standard,
visually inspect following components and replace
deformed parts.
•Suspension components [Front strut assembly
and rear shock absorber assembly]
•Parts connecting suspension and body
4) When no components are deformed, adjust
wheel arch height by replacing coil spring in the
suspension whose wheel arch height is out of stan-
dard.

1. REAR DRIVE SHAFT SHIM SELECTION
1) Insert the rear drive shaft into the reduction drive
gear and center differential assembly.
2) Using the ST, measure the depth “A”, which is
from mating surface of extension case to ball bear-
ing outer ring contact surface.
ST 398643600 GAUGE
3) Using the ST, measure the height “B” from the
AT main case mating surface to ball bearing outer
ring contact surface.
ST 398643600 GAUGE
4) Calculation formula:
When clearances are 0.05 mm (0.0020 in):
T (mm) = A – B + 0.23
[T (in) = A – B + 0.009]
When clearances are 0.25 mm (0.0098 in):
T (mm) = A – B +0.03
[T (in) = A – B +0.001]
A: Depth from end of extension case to ball bearing
outer ring contact surface
B: Height from end of AT main case contact surface
to the ball bearing outer ring contact surface
T: Shim thickness
Specification:
0.05 — 0.25 mm (0.0020 — 0.0098 in)
NOTE:
Calculation formula for “T” above is applied when
measuring with the ST (398643600 GAUGE).

[T (in) = (A – α) – ((B – β) – 0.011) – 0.0020]
When clearances are 0.25 mm (0.0098 in):
T (mm) = (A – α) – ((B – β) – 0.28) – 0.25
[T (in) = (A – α) – ((B – β) – 0.011) – 0.0098]
is applied.

2. SELECTION OF DRIVEN PLATE NO. 3
1) Install the drive plate and driven plate to the cen-
ter differential carrier.
2) Measure the depth “A” from the mating surface
of the extension case to the multi-plate clutch
(LSD) piston.
3) Using the ST, measure the height “B” from the
AT main case mating surface to end of ST, and
then subtract the thickness of ST (piston guide) (50
mm (1.97 in)) from measured value.
ST 398744300 PISTON GUIDE
4) Calculation formula:
When clearances are 0.2 mm (0.008 in):
T (mm) = A – B + 0.08
[T (in) = A – B + 0.0031]
When clearances are 0.6 mm (0.024 in):
T (mm) = A – B + 0.32
[T (in) = A – B + 0.0126]
T: Thickness of driven plate No. 3
A: Depth from mating surface of extension case to
multi-plate clutch (LSD) piston
B: Height from AT main case mating surface to end
of ST
Specification:
0.2 — 0.6 mm (0.008 — 0.024 in)
NOTE:
Calculation formula for “T” is applied when measur-
ing using ST (398643600 GAUGE, 398744300
PISTON GUIDE). When not using the ST,
When clearances are 0.2 mm (0.008 in):
T (mm) = A – (B – α – 0.28) – 0.2
[T (in) = A – (B – α – 0.011) – 0.008]
When clearances are 0.6 mm (0.024 in):
T (mm) = A – (B – α – 0.28) – 0.6
[T (in) = A – (B – α – 0.011) – 0.024]
is applied.
T: Thickness of driven plate No. 3
A: Depth from mating surface of extension case to
multi-plate clutch (LSD) piston
B: Height from the AT main case mating surface to
the contact face of the tool that was used as the
substitute of the ST.
