4. Clean the side bearing hub.
5. Place special tool between the side bearing hub of the
gear carrier, and position the notch as shown in the
illustration. Then tighten side bearing mounting bolt.
6. Use a thickness gauge to measure the clearance (A)
between special tools.
7. Remove special tools (MB990835, MB990326).
8. Use a micrometer to measure the shown dimensions (B,
C) of special tools.
9. Install the bearing cap, and then use a cylinder gauge
to measure inside diameter (D) of the bearing cap.
10. Calculate thickness (F) of the required drive pinion rear
shim twice by the following formula. Select a shim which
most closely matches this thickness.
F = A + B + C - 1/2D - 86.00 mm
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 special tool.
"EADRIVE PINION TURNING TORQUE ADJUSTMENT
/OIL SEAL INSTALLATION
1. Insert the drive pinion into the gear carrier, and then install
the following parts in sequence from the carrier rear side.
Drive pinion spacer, drive pinion front shim and drive
pinion front bearing inner race, companion flange.
NOTE
Do not install the oil seal.
2. Tighten the companion flange to the specified torque by
using special tool.

3. Measure the drive pinion turning torque (without the oil
seal).
Standard value:
Bearing divisionTurning torque
New0.88 - 1.17 N·m
Caution
Take care not to fit gear oil on the bearing.
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 spacers.
Also, select the drive pinion spacer from the following
two types.
Height of drive pinion spacer mmIdentification colour
57.72-
57.08Red
5. Remove the companion flange and drive pinion again.
Then insert the drive pinion front bearing inner race into
the gear carrier. Use special tool to press-fit the oil seal.
6. Install the drive pinion assembly and companion flange
with mating marks properly aligned. Tighten the
companion flange self-locking nut to the specified torque
using special tool.

8. If the turning torque is not within the standard value,
check the tightening torque of the companion flange
self-locking nut, and the installation of the oil seal.
"FADRIVE GEAR INSTALLATION
1. Clean the drive gear attaching bolts.
2. Remove the adhesive adhered to the threaded holes
of the drive gear by turning the special tool (tap M8 x
1.0), and then clean the threaded holes by applying
compressed air.
3. Apply the specified adhesive to the threaded holes of
the drive gear.
Specified adhesive:
3M Stud Locking 4170 or equivalent
4. Install the drive gear onto the LSD case with the mating
marks properly aligned. Tighten the bolts to the specified
torque in a diagonal sequence.

"HABEARING CAP INSTALLATION/FINAL DRIVE
GEAR BACKLASH ADJUSTMENT
Adjust drive gear backlash as follows:
1. Assemble the differential case with the side bearing outer
race to the gear carrier.
2. Press the differential case to one side to measure the
clearance of the side bearing outer race and the gear
carrier.
3. Select two pairs of the side bearing spacer with the thickness
derived from the sum of the clearance and a half of pre-load,
0.05 mm.
4. Remove the side bearing with special tools.
NOTE
Hook the claws of the special tool with the side bearing
inner race by using the notches (two areas) of the LSD
case side.
5. Assemble the selected side bearing spacers to each side.
6. Use special tools to press-fit the side bearing inner case
into the LSD case. After installing the outer race, assemble
the LSD case to the gear carrier.
7. Align the mating marks of differential carrier and the bearing
cap with each other to tighten to the specified torque.
Tightening torque: 37±2N
·m
8. Measure the drive gear backlash.
NOTE
Measure at four points or more on the circumference
of the drive gear.
Standard value: 0.11 - 0.16 mm
9. If the backlash is not within the standard value, move the
side bearing spacer as shown in the illustration to adjust
the backlash.
NOTE
The increment of side bearing spacer must be coincided
with the decreased amount.
10. Inspect the tooth condition at the final drive gear and make
an adjustment if required. (Refer to P.27B-39.)

11. Measure the drive gear runout.
Limit: 0.05 mm
12. When drive gear runout exceeds the limit, remove the
differential case and then the drive gears, moving them
to different positions and reinstall them.
13. If adjustment is not possible, replace the differential case
or drive gear and drive pinion as a set.

1. Align the alignment mark on differential case A with that
on differential case B.
2. Tighten the screws connecting differential case A and
B a uniform amount little by little in the diagonal order.
NOTE
If tightening the screws does not bring the two cases
properly together, spring plates are not probably
assembled properly. Reassemble from the start.
