HINT:
Install the bearing to the differential rear case, taking care that
its stamped side comes in contact with SST.
(b) Install the snap ring.
2. INSTALL LOW GEAR
(a) Clean the contact surface of the differential case.
(b) Heat the low gear in boiling water.
(c) Carefully remove the low gear from the water.
(d) After the moisture on the low gear has completely evapo- rated, quickly install the low gear to the differential case.
3. INSTALL PINION SHAFT, PINION GEAR AND THRUST
WASHER
(a) Install the front side gear and thrust washer to the differ- ential front case.
(b) Install the pinion shaft, 2 pinion gears and thrust washers
to the differential front case.
(c) Using a dial indicator, measure the front case backlash.
HINT:
Push the pinion shaft. Minimum backlash: 0.05 mm (0.0020 in.)
If the backlash is not within the specification, replace the thrust
washer with one of the correct size and reinstall the thrust wash-
