DRIVE GEAR RUNOUT
1. Drain the oil.
2. Remove the rear cover.Refer to RFD-22, "
Removal of Differential Assembly" .
3. Attach dummy cover set. Refer to RFD-18, "
DRIVE GEAR TO
DRIVE PINION BACKLASH" .
4. Fit a dial indicator to the drive gear back face.
5. Rotate the drive gear to measure runout.

If outside the repair limit, check drive gear assembly condition;
foreign material may be caught between drive gear and differen-
tial case, or differential case or drive gear may be deformed, etc.
CAUTION:
Replace the drive gear and drive pinion gear as a set.
COMPANION FLANGE RUNOUT
1. Fit a dial indicator onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).
2. Rotate the companion flange to check for runout.
3. Fit a test indicator to the inner side of the companion flange
(socket diameter).
4. Rotate the companion flange to check for runout.
5. If the runout value is outside the repair limit, follow the procedure
below to adjust.
a. Check for runout while changing the phase between companion flange and drive pinion gear by 90° step,
and search for the point where the runout is the minimum.
b. If the runout value is still outside of the limit after the phase has been changed, replace the companion
flange.
c. If the runout value is still outside of the limit after the companion flange has been replaced, possible cause
will be an assembly malfunction of the drive pinion gear and the electronically controlled coupling, mal-
functioning coupling bearing, or malfunctioning of electronically controlled coupling.
TOOTH CONTACT
1. Drain the oil.
2. Remove the rear cover. Refer to RFD-22, "
Removal of Differential Assembly" .
3. Attach dummy cover set. Refer to RFD-18, "
DRIVE GEAR TO
DRIVE PINION BACKLASH" .
4. Thoroughly clean drive gear and drive pinion teeth.
5. Lightly apply a mixture of powdered ferric oxide and oil or the
equivalent. Apply it to 3 to 4 teeth of drive gear drive side.Tool Number : KV389L0010

ASSEMBLY
Assembly of Drive Pinion Assembly
1. Assemble with a drive pinion adjusting shim of the same thick-
ness as was installed prior to disassembly. Using the suitable
drift, press a pinion rear bearing outer race into the carrier case.
CAUTION:

At first, using a hammer, tap the bearing outer race until it
becomes square to the carrier case.

Do not reuse the pinion rear bearing outer race.
2. Using the drift below, press a pinion front bearing outer race into
the carrier case.
CAUTION:

At first, using a hammer, tap the bearing outer race until it
becomes square to the carrier case.

Do not reuse the pinion front bearing outer race.
3. Using the drift below, press a pinion rear bearing inner race into
the drive pinion.
CAUTION:
Do not reuse the pinion rear bearing inner race.
4. After checking and adjusting the tooth contact and backlash of
the hypoid gear following the procedure below, assemble a col-
lapsible spacer to the drive pinion.
CAUTION:

Be careful of the mounting direction of the collapsible
spacer.

Do not reuse the collapsible spacer.
a. Apply differential oil to the pinion rear bearing, and assemble the
drive pinion to the carrier case.

b. Assemble a pinion front bearing inner race to the drive pinion.
Using the drift and suitable stand, press the pinion nut as far as
it can be tightened.
c. Temporarily tighten the removed pinion nut to the drive pinion.
NOTE:
Use the removed pinion nut only for the preload measurement.
d. Fit the drive pinion gear socket onto the drive pinion spline.
Using the pinion nut wrench, tighten the pinion nut to the speci-
fied preload torque.
CAUTION:
The pinion nut is tightened with no collapsible spacer. Be
careful not to overtighten it. While measuring the preload,
tighten it by 5° to 10°.
e. Apply differential oil to the side bearings, and install new side
bearing adjusting shims with the same thickness or re-install the
old ones to the same mounting position they were in prior to dis-
assembly. Install the differential case assembly to the carrier
case. Refer to RFD-28, "
Installation of Differential Assembly" .
f. Install a dummy cover set to check and adjust the tooth contact.
Refer to RFD-19, "
TOOTH CONTACT" .
g. Check and adjust the backlash. Refer to RFD-18, "
DRIVE
GEAR TO DRIVE PINION BACKLASH" .
h. Remove dummy cover set, and remove differential case assembly.
i. Remove pinion nut, pinion front bearing inner race, and remove

6. Using the drift and suitable stand, press the pinion front bearing
inner race to the drive pinion as far as a pinion nut can be tight-
ened.
7. Apply anti-corrosive oil to the thread and seat of the pinion nut,
and temporarily tighten the pinion nut to the drive pinion.
CAUTION:
Do not reuse the pinion nut.
8. Fit the drive pinion gear socket onto the drive pinion gear spline.
Using the pinion nut wrench, adjust the pinion nut tightening
torque and pinion bearing preload torque.
CAUTION:

Do not reuse the pinion nut.

Adjust the lower limit of the pinion nut tightening torque
first.

If the preload torque exceeds the specified value, replace
the collapsible spacer and tighten it again to adjust. Never
loosen the pinion nut to adjust the preload torque.

After adjustment, rotate the drive pinion gear back and forth
2 to 3 times to check for abnormal noise, rotation malfunc-
tion, and other malfunctions.Tool number : ST23860000

Installation of Differential Assembly
1. Assemble new side gear thrust washers with the same thickness as the ones installed prior to disassem-
bly or reinstall the old ones on the side gears.
2. Assemble the side gears, side gear thrust washers, pinion mate gears, and pinion mate thrust washers to
the differential case, and temporarily assemble the pinion mate shaft.
3. Measure the side gear end play following the procedure below,
and select the appropriate side gear thrust washers.

Using a thickness gauge, measure the clearance between
side gear back and the differential case at 3 different points,
while rotating the side gear. Average the 3 readings, and
select the appropriate side gear thrust washer so that the
mean value is within specifications below. (Measure the clear-
ance of the other side as well.)
*: Always check with the Parts Department for the latest parts information.
CAUTION:

Before measurement, place differential case straight up
so that side gear to be measured comes upward. To pre-
vent the side gear from tilting, insert thickness gauges
with the same thickness from both sides.

Select a side gear thrust washer for right and left individually.
4. Assemble the selected side gear thrust washer to the differential case.Tool number : ST35271000
