Differential Case Reassembly

Coat the 2 front differential side gears, 2 side gear thrust washers, 2 front differential pinions and 2 pinion thrust washers with ATF and install them to the differential case.

Coat the front No. 1 differential pinion shaft with ATF, and install it to the differential case.

Hold the differential case in a vise between aluminum plates.

NOTICE:

Do not overtighten the vise.

Place a dial indicator on the tip of the side gear tooth at a right angle.

Hold the pinion gear in the differential case and measure the backlash of the side gear.

Standard backlash:

0 to 0.15 mm (0 to 0.0059 in.)

Using a pin punch (3 mm) and hammer, install the pinion shaft straight pin.

NOTICE:

Align the holes, and install the pinion shaft straight pin.

Using a chisel and hammer, stake the differential case.

NOTICE:

Stake the differential case after adjusting the backlash.

Using SST and a press, install the front differential case rear tapered roller bearing to the differential case.

NOTICE:

Ensure that there is no clearance between the bearing and transaxle housing.

Install the differential assembly to the transaxle case.

Clean the contact surfaces of the transaxle case and transaxle housing.

Install the transaxle housing to the transaxle case with the 20 bolts.

Torque:

Bolt A:

31 N*m{316 kgf*cm, 23 ft.*lbf}

Bolt B:

23 N*m{234 kgf*cm, 17 ft.*lbf}

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

Turning torque:

1.05 to 1.93 N*m (10.70 to 19.67 kgf*cm, 9.29 to 17.08 in.*lbf)

Remove the 20 bolts and the transaxle housing from the transaxle case.

Remove the differential assembly from the transaxle case.

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 heat the ring gear to more than 110°C (230.0°F).

Clean the contact surface of the front differential case.

Align the matchmarks, and install the front differential ring gear case quickly.

NOTICE:

Do not install the bolts while the ring gear is hot.

Tighten the 12 bolts.

Torque:

120 N*m{1,223 kgf*cm, 88 ft.*lbf}

NOTICE:

Tighten the bolts a little at a time in diagonal order.

Coat the lip of a new oil seal with MP grease.

Using SST and a hammer, install the oil seal.
