(1) Fit the spacer to the back face of the side gear, then
install the gear into the differential case.
(2) Fit washer to back of pinion and rotate two pinions at
the same time into position to mesh with the side gear.
(3) Insert the pinion shaft
(4) Measure the backlash between the side gear and
pinion.
Standard value: 0.025
- 0.150 mm (.OOl - .0059 in.)
(5) If the backlash is out of specification, select the
appropriate spacer and disassemble and reassemble
the gears as necessary.
NOTEAdjust so that the backlash in both side gears equals.
4. INSTALLATION OF LOCK PIN
Align the lock pin hole in pinion shaft with that in the case
and install the lock pin.
Cautipn
The lock pin should be lower than the differential case
flange surface.3. INSTALLATION OF BEARING
Using the special tool, press-fit the bearings into both sides
of the differential case.

3. REMOVAL OF PROPELLER SHAFT
(1) Make mating marks on the differential companion
flange and flange yoke.
CautionRemove the propeller shaft in a straight and level
manner so as to ensure that the boot is
notdamaged through pinching.
NOTEDamage to the boot can be avoided, and the work will
be easier, if a piece of cloth or similar material is
inserted in the boot.
(2) Use the special tool provided as a cover to prevent the
entry of foreign objects into the transfer.
4. REMOVAL OF SPACER
The number of spacers necessary may differ from one
location to another (front, rear, right, left). Record the
number of spacers used to ensure correct installation.
INSPECTIONM25GCAIl Check the sleeve yoke, center yoke and flange yoke for
wear, damage or cracks.
l Check the propeller shaft yokes for wear, damage or
cracks.
lCheck the propeller shaft for bends, twisting or damage.
l Measure the propeller shaft runout with a dial indicator.
Limit:
Front propeller shaft0.6 mm (.024 in.) or less
Center propeller shaft0.6 mm (.024 in.) or less
Rear propeller shaft0.6 mm (.024 in.) or less
NOTESet the V-blocks as much as possible to the end of the
shaft. Measure deflection at the center of the shaft.
