HINT: Use a torque wrench with a fulcrum length of 160 mm (6.3 in.).

(a) Install a new snap ring to the outer race of the radial ball bearing rear.

HINT: When replacing the bearing, also replace the counter driven gear with a new one.

(b) Using a piston ring compressor, squeeze the snap ring.

(c) Using SST and a press, press in the outer race of the radial ball bearing rear.

SST 09950-60020 (09951-00890), 09950-70010 (09951-07100)

NOTICE: Be sure not to damage the snap ring during outer race installation.

(d) Install the underdrive planetary ring gear to the counter driven gear.

(e) Using a snap ring pliers, install the snap ring.

2. INSTALL UNDERDRIVE PLANETARY GEAR ASSEMBLY

(a) Using SST and a press, press the radial ball bearing rear in the underdrive planetary gear.

SST 09502-12010, 09950-60010 (09951-00260), 09950-70010 (09951-07100)

NOTICE: Press the bearing until it becomes flat at the bottom.

(b) Install the counter driven gear with planetary ring gear to the underdrive planetary gear.

(c) Using SST and a press, press in the radial ball bearing front.

SST 09502-12010, 09950-60010 (09951-00260), 09950-70010 (09951-07100)

NOTICE: Press the counter driven gear while rotating it.

(d) Using SST and a press, press in the parking lock gear.

SST 09502-12010, 09950-60010 (09951-00260), 09950-70010 (09951-07100)

NOTICE: Press the counter driven gear while rotating it.

3. INSTALL DIFFERENTIAL DRIVE PINION

(a) Using SST and a press, press the differential drive pinion.

SST 09726-40010, 09950-60010 (09951-00260), 09950-70010 (09951-07100)

NOTICE: Press the counter driven gear while rotating it

4. INSTALL CYLINDRICAL ROLLER BEARING RACE INNER

(a) Using SST and a press, press the cylindrical roller bearing race inner.

SST 09506-35010, 09950-60010 (09951-00260), 09950-70010 (09951-07100)

NOTICE: Press the counter driven gear while rotating it.

5. INSTALL FRONT PLANETARY GEAR NUT

(a) Place the underdrive planetary gear in a soft jaw vise.

NOTICE: Be careful not to damage the differential drive pinion.

(b) Using a socket wrench, install a new lock nut.

Torque: 280 N*m (2,885 kgf*cm, 207 ft.*lbf)

HINT: Use a torque wrench with a fulcrum length of 750 mm (29.53 in.).

(c) Using a pin punch and hammer, stake the lock nut.

CAUTION: Be sure that there are no cracks on the nut.

6. INSPECT UNDERDRIVE PLANETARY GEAR PRELOAD
