4.

Clean the side bearing seat thoroughly.

5.

Set the special tool on the side bearing seats, and position
the cutout section as shown in the illustration. Then confirm
that the special tool contacts with the side bearing seats
completely.

6.

Use a thickness gauge to measure the clearance (A)
between the special tools.

7.

Remove special tools MB990720, MB990858, MB991169
and MB991170.

8.

Use a micrometer to measure dimensions (B) and (C)
of the special tools.

9.

Install the bearing cap, and then use a cylinder gauge
and the micrometer to measure the inside diameter (D)
of the bearing cap as shown in the illustration.

10. Calculate the thickness (F) of the drive pinion rear shim

from the following equation, and select the shim that is
closest in thickness to this value.

F = A + B + C – 1/2 D – 100

11. Fit the selected drive pinion rear shim(s) to the drive pinion,

and press-fit the drive pinion rear bearing inner race by
using the special tool.

DRIVE PINION TURNING TORQUE ADJUSTMENT

Adjust the drive pinion turning torque by using the following
procedure:
1.

Insert the drive pinion into the differential carrier, and then
install the drive pinion spacer, the drive pinion front shim,
the drive pinion front bearing inner race, and the companion
flange in that order.

NOTE
Do not install the oil seal.

2.

Use the special tool to hold the companion flange, and then
tighten the companion flange self-locking nut to the
specified torque.

3.

Use the special tool to measure the drive pinion turning
torque (without the oil seal).

Standard value:

0.59 – 0.88

New or reusing

Gear oil applied

0.39 – 0.49

4.

If the drive pinion turning torque is not within the standard
value, adjust the turning torque by replacing the drive
pinion front shim(s) or the drive pinion spacer.

NOTE
When selecting the drive pinion front shims, if the number
of shims is large, reduce the number of shims to a minimum
by selecting the drive pinion spacer.
Select either of the following drive pinion spacers.

5.

Remove the companion flange and drive pinion once again.
Insert the drive pinion front bearing inner race into the
differential carrier, and then use the special tool to tap
in the oil seal into the differential carrier.

6.

Install the drive pinion assembly and the companion flange
with mating marks properly aligned. Install the new
self-locking nut, then use the special tool to hold the
companion flange, and tighten the self-locking nut to the
specified torque.

7.

Use the special tool to check that the drive pinion turning
torque (with the oil seal) is within the standard value.

Standard value:

8.

If the drive pinion turning torque is not within the standard
value, check the tightening torque of the companion flange
self-locking nut and the oil seal installation condition.

DIFFERENTIAL GEAR BACKLASH ADJUSTMENT

Adjust the differential gear backlash by the following
procedures:
1.

Assemble the side gears, side gear spacers, pinion gears
and pinion washers into the differential case.

2.

Temporarily install the pinion shaft.

NOTE
Do not drive in the lock pin yet.

3.

Insert a wooden wedge between the side gear and the
pinion shaft to lock the side gear.

4.

Measure the differential gear backlash with a dial indicator
on the pinion gear.

NOTE
The measurement should be made for both pinion gears
individually.

Standard value: 0.01 – 0.25 mm

Limit: 0.2 mm

5.

If the differential gear backlash exceeds the limit, adjust
the backlash by replacing the side gear spacers.

6.

If adjustment is not possible, replace the side gears and
pinion gears as a set.

7.

After adjustment, check that the backlash does not exceed
the limit and the differential gear turns smoothly.

DRIVE GEAR INSTALLATION

1.

Clean the drive gear attaching bolts.

2.

Remove the adhesive adhered to the threaded holes of
the drive gear by using a tap, and then clean the threaded
holes by applying compressed air.

3.

Install the drive gear onto the differential case with the
mating marks properly aligned.

Tightening torque: 78 – 88 Nm
