10. Using a brass rod or equivalent (A), tap drive pinion adjusting
shim evenly from the 2 cutouts on gear carrier and remove drive
pinion adjusting shim and pinion rear bearing outer race.
CAUTION:
Be careful not to damage gear carrier.
11. Perform inspection after disassembly. Refer to
ASSEMBLY
1.
Install a drive pinion adjusting shim of the same thickness as
was installed prior to disassembly. Press pinion rear bearing
outer race into gear carrier, using the drift (A) (SST:
ST33200000).
CAUTION:
• At first, using a hammer, tap bearing outer race until it
becomes flush to gear carrier.
• Never reuse pinion rear bearing outer race.
2.
Press pinion front bearing outer race into gear carrier, using the
drift (A) (SST: ST33230000).
CAUTION:
• At first, using a hammer, tap bearing outer race until it
becomes flush to gear carrier.
• Never reuse pinion front bearing outer race.
3.
Press pinion rear bearing inner race to drive pinion, using the
drift (A) (SST: ST23860000).
CAUTION:
Never reuse pinion rear bearing inner race.
4.
Check and adjust the tooth contact and back lash of drive gear and drive pinion following the procedure
below.
a.
Assemble drive pinion into gear carrier.
CAUTION:
• Never assemble collapsible spacer.
• Apply gear oil to pinion rear bearing.
b.
Assemble pinion front bearing inner race to drive pinion assembly.
CAUTION:
• Never reuse pinion front bearing inner race.
• Apply gear oil to pinion front bearing.

DRIVE PINION
c.
Using the drifts (A and C) and press stand (B), press pinion front
bearing inner race to drive pinion as far as drive pinion lock nut
can be tightened.
d.
Temporarily tighten removed drive pinion lock nut to drive pinion.
NOTE:
Use removed drive pinion lock nut only for the preload measure-
ment.
e.
Rotate drive pinion more than 20 times to adjust bearing.
f.
Fit the drive pinion socket (A) onto the drive pinion. Using the
pinion nut wrench (B), tighten drive pinion lock nut holding drive
pinion, while adjusting pinion bearing preload torque using pre-
load gauge (C).
CAUTION:
Drive pinion lock nut is tightened with no collapsible
spacer. Be careful not to overtighten it. While measuring the
preload, tighten it by 5
°
to 10
°
.
g.
Install new side bearing adjusting shims (2 pieces for one side)
with the same thickness or re-install the old ones to the same
mounting position they were in prior to disassembly. Install dif-
ferential assembly to gear carrier. Refer to
CAUTION:
Apply differential gear oil to the side bearings.
h.
Check and adjust tooth contact, drive gear to drive pinion back-
lash. Refer to
i.
Remove differential assembly.
j.
Remove drive pinion assembly from gear carrier
k.
Remove drive pinion nut and press drive pinion assembly out of gear carrier.
l.
Remove pinion front bearing inner race.
5.
Assemble collapsible spacer
to drive pinion
.
CAUTION:
• Be careful of the mounting direction of collapsible spacer.
• Never reuse collapsible spacer.
6.
Assemble drive pinion into gear carrier.
CAUTION:
Apply gear oil to pinion rear bearing.
7.
Assemble pinion front bearing inner race to drive pinion assem-
bly.
CAUTION:
• Never reuse pinion front bearing inner race.
• Apply gear oil to pinion front bearing.

8.
Using the drifts (A and C) and press stand (B), press pinion front
bearing inner race to drive pinion as far as drive pinion lock nut
can be tightened.
9.
Apply anti-corrosion oil to the thread and seat of drive pinion
lock nut, and temporarily tighten drive pinion lock nut to drive
pinion.
CAUTION:
Never reuse drive pinion lock nut.
10. Fit the drive pinion socket (A) onto the drive pinion. While hold-
ing drive pinion, tighten drive pinion lock nut within the limits of
specified torque so as to keep the pinion bearing preload within
a standard values, using the pinion nut wrench (B) and the pre-
load gauge (C).
CAUTION:
• Adjust the lower limit of the drive pinion lock nut tighten-
ing torque first.
• If the preload torque exceeds the specified value, replace
collapsible spacer and tighten it again to adjust. Never
loose n drive pinion lock nut to adjust the preload torque.
• After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
11. Install differential assembly. Refer to
DLN-247, "Disassembly and Assembly"
.
CAUTION:
Never install rear cover at this timing.
12. Check and adjust drive gear runout, tooth contact, and drive gear to drive pinion backlash. Refer to
13. Remove dummy cover set, then install rear cover, and side oil seal. Refer to
14. Check total preload torque. Refer to
.
15. Using the drift (A) (SST: ST35271000), install drive pinion oil
seal
within the dimension (D) shown as follows.
CAUTION:
• Never reuse oil seal.
• When installing, never incline oil seal.
• Apply multi-purpose grease onto oil seal lips, and gear oil
onto the circumference of oil seal.
16. Install electric controlled coupling assembly. Refer to

INSPECTION AFTER DISASSEMBLY
Drive Gear and Drive Pinion
• Clean up the disassembled parts.
• If the gear teeth never mesh or line-up correctly, determine the cause and adjust or replace as necessary.
• If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new drive
gear and drive pinion as a set.
Bearing
• Clean up the disassembled parts.
• If any chipped (by friction), pitted, worn, rusted or scratched marks, or unusual noise from the bearing is
observed, replace as a bearing assembly (as a new set).
Oil Seal
• Whenever disassembled, replace.
• If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace them.
