AX
INSPECTION
1. INSPECT FRONT DIFFERENTIAL
(a) Using a dial indicator, measure the backlash of one
pinion gear while holding the front differential side
gear toward the case.
Standard backlash:
0.05 - 0.20 mm (0.0020 - 0.0079 in.)
NOTICE:
Do not mount the surface of front differential
case which contacts with bushing in a vise.
If the backlash is not within the specified value, refer
to the table below and select a thrust washer which
will ensure that the backlash is within the specified
value.
Thrust washer thickness: mm (in.)
(b) Engage the front differential side to the above
mentioned front differential case.
(c) Install the differential case LH to the front differential
case and measure its center.
(d) After that, remove the differential case LH.
(e) Using a straight edge and feeler gauge, measure
the clearance between the front differential case
and the front differential side gear.
HINT:
• t= Thrust washer thickness
• L= Clearance
• t= L-0.162 - 0.265 mm (0.0064 - 0.0104 in.)
If the clearance is not within the specified value,
refer to the table below and select a thrust washer
which will ensure that the clearance is within the
specified value.
Thrust washer thickness: mm (in.)

If the clearance is not within the specified value,
parts may have been assembled incorrectly, so
check and reassemble it.
2. INSPECT CENTER DIFFERENTIAL
(a) Pressing and holding the differential spider toward
the differential case RH, measure the pinion's
backlash with a dial indicator as illustrated.
Standard backlash:
0.05 - 0.20 mm (0.0020 - 0.0079 in.)
If the backlash is not within the specified value, refer
to the table below and select a thrust washer which
will ensure that the backlash is within the specified
value.
Thrust washer thickness: mm (in.)
(b) Temporarily install the differential side gear thrust
washer No.2 LH, center differential side gear conical
spring washer and differential case No.2 to the
differential case LH.
HINT:
Ensure that the conical washers is installed
correctly.
(c) Install the differential intermediate case to the above
and fix them with 4 bolts.
