Dimension “G” measurement
• Measure dimension from ring gear shaft bearing mounting sur-
face of ring gear to transfer case side edge surface with a
micrometer and straightedge. Refer to “Measuring point”.
CAUTION:
Consider the thickness of a straightedge.
Dimension “H” measurement
• Measure dimension from transfer case side edge surface of
ring gear to adapter case side edge surface with a pair of ver-
nier calipers. Refer to “Measuring point”.
Dimension “I” measurement
• Measure dimension from ring gear mounting surface of ring
gear shaft to ring gear shaft bearing (transfer case side)
mounting surface with a pair of vernier calipers. Refer to “Mea-
suring point”.
Dimension “J” measurement
• Measure dimension from outer race edge surface of ring gear
shaft bearing (transfer case side) to inner race edge surface
with a pair of vernier calipers. Refer to “Measuring point”.
2.
Calculate dimension “N” by the formula below.
3.
Convert the dimensions “F”, “G”, “H”, “I”, “J” and “N” according to the standards below.

4.
Check dimension “Z” (machining difference) on the ring gear
back surface.
NOTE:
Dimension “Z” indicates difference between optimum engage-
ment and the standard dimensions in increments of 0.01 mm
(0.0004 in) written on the ring gear back surface.
5.
Calculate the thickness of the ring gear adjusting shim (transfer
case side) “T
2
” by the formula below.
6.
Select ring gear adjusting shim (transfer case side).
CAUTION:
• Only one adjusting shim can be selected.
• Select the closest one, favoring thicker over thinner when necessary if no adjusting shim with
the calculated value is available.
Drive Pinion Adjusting Shim
1.
Check the dimension “U” (machining difference) between old
and new drive pinions when hypoid gear set (drive pinion and
ring gear) has been replaced.
(Assemble new drive pinion adjusting shims with the same thick-
ness as the ones removed prior to disassembly or removed
drive pinion adjusting shims when reusing the hypoid gear set.)
NOTE:
Dimension “U” indicates the difference between optimum
engagement and the standard dimensions in increments of 0.01
mm (0.0004 in). It is written on the gear end of the drive pinion
for reference.
2.
Calculate the thickness of the drive pinion adjusting shim “T” by
the formula below.
3.
Select drive pinion adjusting shim.

M/T : Inspection After Disassembly
INFOID:0000000000972148
Check items below. If necessary, replace them with new ones.
GEAR AND SHAFT
Check gear face and shaft for wear, cracks, damage, and seizure.
CAUTION:
Replace ring gear and drive pinion as a set (hypoid gear set) if any malfunction is detected on the ring
gear or drive pinion.
BEARING
Check for seizure, peeling, wear, corrosion, sticking, unusual noise, roughness in hand turning, and other
damage.
CAUTION:
Always replace inner race and outer race as a pair when replacing the bearing.
SHIM
Check for seizure, damage, and unusual wear.
CASE
Check the bearing mounting surface for wear, cracks and damages.
