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 18 bolts
Torque : 22 Nm (224 kgf-cm, 16 ft-lbf for bolt A)
Torque : 29 Nm (296 kgf-cm, 21 ft-lbf for bolts B and C)
Torque : 10 Nm (102 kgf-cm, 7 ft-lbf for bolt D)
HINT
Each bolt length is indicated below.
Bolt length:
50 mm (1.969 in.) for bolt A, B and D
42 mm (1.654 in.) for bolt C
NOTICE:
Usually, bolt A is non-reusable bolt. In this case, however, it can be used after cleaning it.
(d) Using SST, return the differential assembly right and left 2 or 3 times to allow the bearing settle.
SST : 09564-32011
(e) Using SST and torque wrench, measure the turning torque of the differential.
SST : 09564-32011
Standard turning torque at 60 rpm - Torque : 0.20 to 0.69 Nm (2.0 to 7.0 kgf-cm, 1.8 to 6.1 in-lbf)
HINT
If the turning torque is not within the specified value, refer to the table below and select a thrust washer which turning torque is within the specified value.
Standard flange thickness:
(f) Remove the 18 bolts and the transaxle housing.
(g) Remove the differential assembly.
7. INSTALL FRONT DIFFERENTIAL RING GEAR
(a) Using ATF and a heater, heat the front differential ring gear to 90 to 110 °C (194.0 to 230.0 °F)
NOTICE:
Do not overheat the ring gear to 110°C (230.0°F) or more.
(b) Clean the contract surface of the front differential case.
(c) Align the matchmarks, and install the front differential ring gear case quickly.
NOTICE:
Do not install the bolts while the ring gear is hot.
(d) Tighten the 14 bolts.
Torque : 95 Nm (969 kgf-cm, 70 ft-lbf)
NOTICE:
Tighten the bolts a little at a time in diagonal order.
