D: ADJUSTMENT
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).

When clearances are 0.05 mm (0.0020 in):
T (mm) = (A – α) – ((B – β) – 0.28) – 0.05
[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
