6. ADJUST DIFFERENTIAL SIDE BEARING PRELOAD
(a) Install the differential assembly to the transaxle case.
(b) Clean the contact surfaces of the transaxle case and transaxle housing.
(c) Install the transaxle housing to the transaxle case and tighten them with the 18 bolts.
Bolt A and D - Torque: 22 Nm (225 kgf-cm, 16 ft-lbf)
Bolt B and C - Torque: 29 Nm (300 kgf-cm, 22 ft-lbf)
Bolt E - Torque: 10 Nm (102 kgf-cm, 7 ft-lbf)
HINT: Each bolt length is indicated below.
Bolt length:
Bolt A 50 mm (1.969 in.)
Bolt B 50 mm (1.969 in.)
Bolt C 42 mm (1.654 in.)
Bolt D 72 mm (2.834 in.)
Bolt E 50 mm (1.969 in.)
NOTE: Usually, bolts A are non-reusable bolts. In this case, however, they can be used after cleaning.
(d) Using SST, turn the differential assembly right and left 2 or 3 times to allow the bearing to settle.
SST: 09564-32011
(e) Using SST and a torque wrench, measure the differential preload.
SST: 09564-32011
Standard preload at 60 rpm:
0.20 to 0.69 N*m (2.0 to 7.0 kgf*cm, 1.8 to 6.1 in.*lbf)
HINT: If the preload is not within the specified value, refer to the table below and select an appropriate thrust washer to adjust preload to within the specified value.
Thrust Washer 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 to 230°F).
NOTE: Do not heat the ring gear to over 110°C (230°F).
(b) Clean the contact surface of the front differential case.
(c) Align the matchmarks, and 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 Nm (969 kgf-cm, 70 ft-lbf)
NOTE: Gradually tighten the bolts in diagonal order.
8. INSTALL DIFFERENTIAL SIDE BEARING RETAINER OIL SEAL
