Coat the front No. 1 differential pinion shaft with ATF, and install it to the front differential case.
INSPECT DIFFERENTIAL SIDE GEAR BACKLASH
Hold the front differential case in a vise between aluminum plates.
Note
Do not overtighten the vise.
Place a dial indicator on the tip of the differential side gear tooth at a right angle.
Hold the front differential pinion in the front differential case and measure the backlash of the differential side gear.

Note
Ensure that there is no clearance between the front differential case rear tapered roller bearing (outer race) and transaxle case sub-assembly.
INSTALL FRONT DIFFERENTIAL CASE FRONT TAPERED ROLLER BEARING
Using SST and a press, install a new front differential case front tapered roller bearing (inner race) to the front differential case.
Note

Install the shim to the transaxle housing.
Using SST and a hammer, install a new front differential case front tapered roller bearing (outer race) to the transaxle housing.
Note
Ensure that there is no clearance between the front differential case front tapered roller bearing (outer race) and transaxle housing.
ADJUST DIFFERENTIAL SIDE BEARING PRELOAD
Remove the seal packing from the contact surfaces between the transaxle housing and transaxle case sub-assembly.
Install the front differential case to the transaxle case sub-assembly.
Install the transaxle housing to the transaxle case sub-assembly with the 20 bolts.
Using SST and a torque wrench, measure the turning torque of the differential side bearing while rotating SST at 10 rpm.
| Turning torque |
|---|
| TMC or AISIN AW made |
| 1.3 to 1.7 N*m (14 to 17 kgf*cm, 12 to 15 in.*lbf) |
| AWNC made |
| 0.9 to 1.3 N*m (9 to 13 kgf*cm, 8 to 11 in.*lbf) |
Tech Tips
Three different automatic transaxle assembly models manufactured at different factories are available for this vehicle.
Referring to the introduction section, check the serial number. Confirm the factory at which the automatic transaxle assembly was manufactured according to the following table.
| Serial Number | Factory |
|---|---|
| ##A######## | AISIN AW made |
| ##T######## | TMC made |
| ##N######## | AWNC made |
If the turning torque is not within the specified range, refer to the table below to select a shim so that the turning torque is within the specified range.
| Thickness | Thickness | Thickness | Thickness |
|---|---|---|---|
| 2.000 (0.0787) | 2.225 (0.0876) | 2.450 (0.0965) | 2.675 (0.105) |

Remove the 20 bolts and the transaxle housing from the transaxle case sub-assembly.
Remove the front differential case from the transaxle case sub-assembly.
INSTALL FRONT DIFFERENTIAL RING GEAR
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 front differential ring gear to more than 110°C (230°F).
Clean the contact surface of the front differential case.
Align the matchmarks, set the front differential ring gear to the front differential case.
| *a | Matchmark |
Install the 12 bolts.
Note
Tighten the bolts after the front differential ring gear has cooled down sufficiently.
Tighten the bolts evenly in a diagonal pattern using several steps.
INSTALL TRANSAXLE CASE OIL SEAL
Coat the lip of a new transaxle case oil seal with a small amount of MP grease.
Using SST and a hammer, tap in the transaxle case oil seal.
| Oil seal tap in depth |
|---|
| -0.5 to 0.5 mm (-0.0197 to 0.0197 in.) |
Note
Check that the transaxle case oil seal is installed in the correct direction.
INSTALL FRONT TRANSAXLE CASE OIL SEAL
