Disassembly

DISASSEMBLY

PROCEDURE

1. REMOVE FRONT DIFFERENTIAL CASE REAR TAPERED ROLLER BEARING (OUTER RACE)

(a) Using SST, remove the front differential case rear tapered roller bearing (outer race) from the automatic transaxle case sub-assembly.

SST: 09308-36010

NOTICE:

Be careful not to damage the automatic transaxle case sub-assembly.

HINT:

Align the claw of the SST with the indentation of the automatic transaxle case sub-assembly when removing the parts.

2. REMOVE FRONT DIFFERENTIAL CASE REAR TAPERED ROLLER BEARING (INNER RACE)

(a) Using SST, remove the front differential case rear tapered roller bearing (inner race) from the differential case assembly.

SST: 09950-40011

09951-04010

09952-04010

09953-04030

09954-04020

09955-04011

09957-04010

SST: 09950-60011

09951-00340

09951-00440

09952-06010

NOTICE:

Because SST is attached to the roller portion, there is a possibility that the roller portion could break and SST could come off before the front differential case rear tapered roller bearing (inner race) comes off.

(b) If the roller portion breaks and SST comes off, reattach SST to the inner race in the position shown in the illustration, and continue removing the parts.

3. REMOVE FRONT DIFFERENTIAL CASE FRONT TAPERED ROLLER BEARING (OUTER RACE)

(a) Using SST, remove the front differential case front tapered roller bearing (outer race) and differential drive pinion shim from the transaxle housing.

SST: 09308-36010

NOTICE:

Be careful not to damage the transaxle housing.

HINT:

Align the claw of the SST with the indentation of the transaxle housing when removing the parts.

4. REMOVE FRONT DIFFERENTIAL CASE FRONT TAPERED ROLLER BEARING (INNER RACE)

(a) Using SST, remove the front differential case front tapered roller bearing (inner race) from the differential case assembly.

Inspection

INSPECTION

PROCEDURE

1. INSPECT DIFFERENTIAL CASE ASSEMBLY

(a) Using SST, rotate the front differential side gear as shown in the illustration.

SST: 09528-52010

09528-05030

Standard:

The front differential side gear does not lock when rotated in either direction.

If the result is not as specified, replace the differential case assembly.

Reassembly

REASSEMBLY

PROCEDURE

1. INSTALL FRONT DIFFERENTIAL CASE FRONT TAPERED ROLLER BEARING (INNER RACE)

(a) Using SST and a press, install a new front differential case front tapered roller bearing (inner race) to the differential case assembly.

SST: 09316-20011

SST: 09950-60021

09951-00890

SST: 09950-70010

09951-07200

NOTICE:

Do not damage the front differential case front tapered roller bearing (inner race) cage when installing the front differential case front tapered roller bearing (inner race).
Be sure to install the front differential case front tapered roller bearing (inner race) so that there is no clearance between the front differential case front tapered roller bearing (inner race) and the differential case assembly. If there is any clearance, the turning torque of the differential case assembly cannot be measured correctly.

2. INSTALL FRONT DIFFERENTIAL CASE FRONT TAPERED ROLLER BEARING (OUTER RACE)

(a) Using SST and a hammer, install the differential drive pinion shim and a new front differential case front tapered roller bearing (outer race) to the transaxle housing.

SST: 09950-60021

09951-00890

SST: 09950-70010

09951-07200

NOTICE:

Be sure to install the front differential case front tapered roller bearing (outer race) so that there is no clearance between the front differential case front tapered roller bearing (outer race), differential drive pinion shim and the transaxle housing. If there is any clearance, the turning torque of the differential case assembly cannot be measured correctly.

3. INSTALL FRONT DIFFERENTIAL CASE REAR TAPERED ROLLER BEARING (INNER RACE)

(a) Using SST and a press, install a new front differential case rear tapered roller bearing (inner race) to the differential case assembly.

SST: 09316-20011

SST: 09950-60021

09951-00890

SST: 09950-70010

Do not damage the front differential case rear tapered roller bearing (inner race) cage when installing the front differential case rear tapered roller bearing (inner race).
Be sure to install the front differential case rear tapered roller bearing (inner race) so that there is no clearance between the front differential case rear tapered roller bearing (inner race) and the differential case assembly. If there is any clearance, the turning torque of the differential case assembly cannot be measured correctly.

4. INSTALL FRONT DIFFERENTIAL CASE REAR TAPERED ROLLER BEARING (OUTER RACE)

(a) Using SST and a hammer, install a new front differential case rear tapered roller bearing (outer race) to the automatic transaxle case sub-assembly.

SST: 09951-00850

SST: 09950-70010

09951-07200

NOTICE:

Be sure to install the front differential case rear tapered roller bearing (outer race) so that there is no clearance between the front differential case rear tapered roller bearing (outer race) and the automatic transaxle case sub-assembly. If there is any clearance, the turning torque of the differential case assembly cannot be measured correctly.
