(1) Fit a spacer on to the back of the side gear and then
install the gear in the differential case.
Caution
When a new side gear is used, use a spacer of
intermediate thickness

TFMOOOE(2) Place a washer at the back of each of the two pinions
and insert the two pinions at the same time, meshing
them with the side gear and rotating them.
(3) Insert the pinion shaft.
(4) Measure the backlash between the side gear and
pinion.Standard value: 0.025
- 0.150 mm (.OOOl - .0060 in.)
(5) If the backlash is out of specification, disassemble and
reassemble the gears with a new spacer.
Caution
Adjust to provide the same backlash for both side
gears.4. INSTALLATION OF LOCK PIN
Align the lock pin hole in the pinion shaft with that in the
case and press the lock pin into position.
Caution
1. Do not reuse the lock pin.
2.Make sure that the lock pin head is lower than the
differential case flange surface.
3. INSTALLATION OF BALL BEARINGS
Install the ball bearings in both sides of the differential case.
