Differential Case: Inspection

INSPECT BACKLASH

Measure the side gear backlash while holding 1 pinion gear toward the case.
Standard backlash: 0.05 to 0.20 mm (0.0020 to 0.0079 in.)

If the backlash is out of specification, install the correct thrust washer to the side gear.

Referring to the table below, select thrust washers which will ensure that the backlash is within for both sides.

THRUST WASHER THICKNESS SPECIFICATION

Thickness	Thickness
0.95 (0.0374)	1.10 (0.0433)
1.00 (0.0394)	1.15 (0.0453)
1.05 (0.0413)	1.20 (0.0472)

If the backlash is not within the specification, install a thrust washer of a different thickness.

INSPECT TAPERED ROLLER BEARING PRELOAD

Coat the front differential case and bearing with ATF and install them to the transaxle case.
Install the 14 bolts and transaxle housing.
Torque: Bolt A

29.4 N*m (300 kgf*cm, 22 ft.*lbf)

Bolt B

221 N*m (225 kgf*cm, 16 ft.*lbf)

Using SST and small torque wrench, measure the preload of the differential gear.

SST 09564-32011

Torque: New bearing

0.98 to 1.57 N*m (10.0 to 16.0 kgf*cm,

8.7 to 13.9 in.*lbf)

Used bearing

0.49 to 0.78 N*m (5.0 to 8.0 kgf*cm, 4.3 to 6.9 in.*lbf)

If the preload is not within the specification, remove the differential from the transaxle case. Re-select the transaxle case side adjusting shim according to the following table.
