5. Remove no. 1 Front differential pinion shaft

1. 1
   Remove the front differential pinion shaft from the differential case.
2. 2
   Remove front differential side gear

   

1. 1
   Remove the 2 front differential pinions, 2 pinion thrust washers, 2 front differential side gears and 2 side gear thrust washers from the differential case.
2. 2
   Remove transaxle housing oil seal

   

1. Using sst and hammer, tap out the oil seal.

1. Remove differential side bearing retainer oil seal

1. Using sst and hammer, tap out the oil seal.

1. Inspect differential side gear backlash

1. Using a dial indicator, measure the backlash of the side gear.

Standard thrust washer thickness

1. Install front differential side gear

1. 1
   Coat the 2 front differential side gears, 2 side gear thrust washers, 2 font differential pinions and 2 pinion thrust washers with atf and install them to the differential case.
2. 2
   Install no. 1 Front differential pinion shaft

   

1. 1
   Coat the no. 1 Front differential pinion shaft with atf, and install it to the differential case.
2. 2
   Install transaxle case straight pin

   

1. Using a pin punch and a hammer, tap in the pinion shaft straight pin.

2. Using a chisel and a hammer, stake the differential case.

Stake it after adjusting the backlash.

4. Install front differential case rear tapered roller bearing

1. Using sst and a press, press in the front differential case rear tapered roller bearing to the differential case.

2. Using sst and a hammer, tap in the front differential case tapered roller bearing front outer race to the transaxle housing.

5. Install front differential case front tapered roller bearing

1. Using sst and a press, press in the front differential case rear tapered roller bearing to the differential case.

2. Using sst and a hammer, tap in the front differential case tapered roller bearing front outer race to the transaxle housing.

Clearance is not allowed between the bearing and transaxle housing.

6. Adjust differential side bearing preload

1. Install the differential assembly to the transaxle case.

1. 1
   Clean the matching surfaces of the transaxle case and transaxle housing.
2. 2
   Install the transaxle housing to the transaxle case and tighten them with the 16 bolts

Each bolt length is indicated below.

Usually, bolt a is non-reusable bolt. In this case, however, it can be used after cleaning it.

4. Using sst, return the differential assembly right and left 2 or 3 times to allow the bearing settle.

5. Using sst and torque wrench, measure the turning torque of the differential.

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

6. Remove the 16 bolts and the transaxle housing.

1. 1
   Remove the differential assembly.
2. 2
   Install front differential ring gear

   

1. Using atf and a heater, heat the front differential ring gear to 90 to 110 °c (194.0 To 230.0 °F)

Do not overheat the ring gear to 110°c (230.0°F) or more.

2. Clean the contract surface of the front differential case.

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

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

4. Tighten the 14 bolts.

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

8. Install differential side bearing retainer oil seal

1. 1
   Coat the lip of a new oil seal with a little amount of mp grease.
2. 2
   Using sst and a hammer, tap in the oil seal.

9. Remove transaxle housing oil seal

1. 1
   Coat the lip of a new oil seal with a little amount of mp grease.
2. 2
   Using sst and a hammer, tap in the oil seal.
