6. ADJUST DIFFERENTIAL SIDE BEARING PRELOAD
(a) Install the differential assembly to the transaxle case.
(b) Clean the matching surfaces of the transaxle case and transaxle housing.
(c) Install the transaxle housing to the transaxle case and tighten them with the 16 bolts.
Bolt A - Torque: 25 Nm (255 kgf-cm, 18 ft-lbf)
Bolt B - Torque: 33 Nm (337 kgf-cm, 24 ft-lbf)
Bolt C - Torque: 29 Nm (295 kgf-cm, 21 ft-lbf)
Bolt D - Torque: 22 Nm (224 kgf-cm, 16 ft-lbf)
Bolt length:
Bolt A

Bolt B
50 mm (1.969 in.)
Bolt C
42 mm (1.654 in.)
Bolt D
72 mm (2.835 in.)
HINT: Usually, bolt A is a non-reusable bolt. In this case, however, it can be used after cleaning it.
(d) Using SST, turn the differential assembly right and left 2 or 3 times to settle the bearing.
SST: 09564-32011
(e) Using SST and a torque wrench, measure the turning torque of the differential.
SST: 09564-32011
Turning torque at 60 rpm:
New bearing
0.20 - 0.69 Nm (2.0 - 7.0 kgf-cm, 1.8 - 6.1 in.-lbf)
Used bearing
0.10 - 0.35 Nm (1.0 - 3.6 kgf-cm, 0.9 - 3.1 in.-lbf)
HINT: If the turning torque is not within the specified value, refer to the table below to select a thrust washer which turning torque is within the specified value.
Flange thickness: mm (in.)
(f) Remove the 16 bolts and the transaxle housing.
(g) Remove the differential assembly.
7. INSTALL FRONT DIFFERENTIAL RING GEAR
(a) Using ATF and heater, heat the front differential ring gear to 90 - 110 °C (194.0 - 230.0 °F).
NOTE: Do not overheat the ring gear to 110 °C (230.0 °F) or more.
(b) Clean the contact surface of the front differential case.
(c) Align the match-marks, install the front differential ring gear case quickly.
NOTE: Do not install the bolts while the ring gear is hot.
(d) Tighten the 14 bolts.
Torque: 95.1 Nm (970 kgf-cm, 70 ft-lbf)
NOTE: Tighten the bolts a little at a time in diagonal order.
