Clean the matching surfaces of the transaxle case and transaxle housing.
Install the transaxle housing to the transaxle case and tighten them with the 16 bolts.
Torque: 22 N*m (224 kgf*cm, 16 ft.*lbf) for bolt A

29 N*m (295 kgf*cm, 21 ft.*lbf) for bolt B

29 N*m (295 kgf*cm, 21 ft.*lbf) for bolt C

22 N*m (224 kgf*cm, 16 ft.*lbf) for bolt D

HINT:
- Each bolt length is indicated below.
  Bolt length:
  
  50 mm (1.97 in.) for bolt A
  
  50 mm (1.97 in.) for bolt B
  
  42 mm (1.65 in.) for bolt C
  
  72 mm (2.84 in.) for bolt D
- Usually, bolt A is a non-reusable bolt. In this case, however, it can be used after cleaning it.

Using SST, turn the differential assembly right and left 2 or 3 times to allow the bearing to settle.
SST 09564-32011

Using SST and a torque wrench, measure the turning torque of the differential.

SST 09564-32011

Torque: Standard turning torque 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 turning torque is not within the specified value, refer to the table below and select a thrust washer so that the turning torque is within the specified value.
