< UNIT DISASSEMBLY AND ASSEMBLY >
[REAR FINAL DRIVE: R145]
DIFFERENTIAL ASSEMBLY
1. Install side gear thrust washers with the same thickness as the
ones installed prior to disassembly or reinstall the old ones on
the side gears.
2. Install side gears and side gear thrust washers into differential
case.
3. Align 2 pinion mate gears in diagonally opposite positions, then
rotate and install them into differential case after installing thrust
washer to pinion mate gear.
4. Align the lock pin holes on differential case with pinion mate
shaft, and install pinion mate shaft.
5. Measure side gear end play. If necessary, select the appropriate side gear thrust washers.
a. Place differential assembly straight up so that side gear to be
measured comes upward.

b. Using feeler gauge, measure the clearance between side gear
back and differential case at 3 different points, while rotating
side gear. Average the 3 readings, and then measure the clear-
ance of the other side as well.
CAUTION:
To prevent side gear from tilting, insert feeler gauges with
the same thickness from both sides.
• If the back clearance is outside the specification, use a thicker/
thinner side gear thrust washer to adjust. For selecting thrust
washer, refer to the latest parts information.
CAUTION:
Select a side gear thrust washer for right and left individu-
ally.
6. Drive a lock pin into pinion mate shaft, using the pin punch
(commercial service tool).
CAUTION:
Never reuse lock pin.
7. Press side bearing inner races to differential assembly, using the
drifts (A and B).
CAUTION:
• Never reuse side bearing inner race.
• Apply gear oil to side bearing.
8. Apply thread locking sealant into the thread hole of drive gear.
CAUTION:
Clean and degrees drive gear back and threaded holes suf-
ficiently.
9. Install the drive gear to differential assembly.
CAUTION:
Align the matching mark of differential assembly and drive
gear.
Side gear back clear-
ance
: Refer to
.
When the back clearance
is large
: Use a thicker thrust washer.
When the back clearance
is small
: Use a thinner thrust washer.

DIFFERENTIAL ASSEMBLY
10. Tighten the bolts in a crisscross fashion to the specified torque.
• For tightening torque, refer to
CAUTION:
Apply anti-corrosion oil to the thread and seat of mounting
bolts.
11. Assemble side bearing outer races to inner races.
CAUTION:
• Never reuse side bearing outer race.
• Apply gear oil to side bearing.
12. Install new side bearing adjusting shims (2 pieces for one side)
with the same thickness as the ones installed prior to disassem-
bly or re-install the old ones, on side bearing outer race of differ-
ential assembly.
If side bearing adjusting shims have been already selected, use them.
13. Set the drifts (A and B) to the right and left side bearing adjusting
shims individually. Compress differential assembly and side
bearing to gear carrier assembly to install differential assembly.
CAUTION:
• The drift shall be placed on the center of the adjusting
shims.
• The pressure shall be as low as possible to install differ-
ential assembly into gear carrier assembly. The maximum
pressure shall be 10 kN (1 ton, 1.1 US ton, 1.0 Imp ton).
• If the adjusting shims are installed by tapping, the gear carrier may be damaged. Avoid tapping.
14. Install dummy cover set [SST: KV381086S1 ( — )], check and adjust drive gear runout, tooth contact,
backlash, and total preload torque. Refer to
.
15. Remove dummy cover set.
16. Install stud bolt to rear cover.
CAUTION:
Screw the stud bolt until the thread becomes invisible by applying a torque of 20 N·m (2.0 kg-m, 15
ft-lb) or less.
17. Apply liquid gasket to mating surface of rear cover.
CAUTION:
• Remove old gasket adhering to the mounting surfaces.
Also remove any moisture, oil, or foreign material adher-
ing to the mounting surfaces.
• The width of sealant bead is approximately 3 mm (0.12 in).
Apply sealant evenly.
18. Set the drifts (A and B) to the right and left side bearing adjusting
shims individually. Compress differential assembly and side
bearing to install rear cover.
CAUTION:
• The drift shall be placed on the center of the adjusting
shims.

• The pressure shall be as low as possible to install differential assembly into gear carrier assem-
bly. The maximum pressure shall be 10 kN (1 ton, 1.1 US ton, 1.0 Imp ton).
• If the adjusting shims are installed by tapping, the gear carrier may be damaged. Avoid tapping.
19. Tighten rear cover mounting bolts to the specified torque.
• For tightening torque, refer to
20. Using the drift (A) [SST: KV38100200 (J-26233)], drive side oil
seals until it becomes flush with the gear carrier end.
CAUTION:
• Never reuse oil seals.
• When installing, do not incline oil seals.
• Apply multi-purpose grease onto oil seal lips, and gear oil
onto the circumference of oil seal.
21. Check total preload torque. Refer to
.
Adjustment
INFOID:0000000011278422
TOTAL PRELOAD TORQUE
1. Remove electric controlled coupling assembly. Refer to
DLN-122, "Disassembly and Assembly"
2. Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
3. Rotate drive pinion at least 20 times to check for smooth opera-
tion of the bearing.
4. Fit drive pinion socket onto drive pinion spline. Measure the total
preload, using the preload gauge and drive pinion socket.
NOTE:
Total preload torque = Pinion bearing torque + Side bearing torque
• If measured value is out of the specification, disassemble it to check and adjust each part. Adjust the pinion
bearing preload and side bearing preload.
Adjust the pinion bearing preload first, then adjust the side bearing preload.
DRIVE GEAR RUNOUT
1. Remove rear cover. Refer to
DLN-126, "Disassembly and Assembly"
.
2. Following the procedure below, install a dummy cover set [SST: KV381086S1 (
—
)] to gear car-
rier.

Total preload torque
: Refer to
When the preload torque is large
On pinion bearings:

On side bearings:
Use thinner side bearing adjusting shims. For selecting adjusting
shim, refer to the latest parts information.
When the preload is small
On pinion bearings:
Tighten the drive pinion nut.
On side bearings:
Use thicker side bearing adjusting shims. For selecting adjusting
