• Check mating surfaces of differential case, side gears, pinion mate
gears and pinion mate shaft. Replace if necessary.
• Check washers for wear. Replace if necessary.
Bearings
• Make sure bearings roll freely and are free from noise, cracks, pit-
ting or wear. Replace if necessary.
CAUTION:
When replacing taper roller bearing, replace outer and inner
race as a set.
ASSEMBLY

a. Place differential case in the upright position so that the side
gear to be measured is at the top.
(A): Location for inserting feeler gauge
(B): Side gear tooth
(C): The center line of differential case
b. In order to maximize the back clearance, rotate side gears so
that a tooth on side gears at the top and bottom will align at the
same position as shown in the figure.
c. Adjust the back clearance of side gear according to the following
procedures.
i. Insert feeler gauges A of the same thickness to the back of side
gear from both sides, preventing side gear from falling, to mea-
sure the clearance.
• Measure clearance 3 times by rotating side gears and take the
average.
CAUTION:
In all 3 measurements, maximize the clearance by aligning
teeth on side gears at the top and bottom at the same posi-
tion.
ii. Select side gear thrust washer so that the clearance will fall
within the standard.
iii. Turn differential case upside down, and measure the back clear-
ance of the other side gear in the same manner.
NOTE:
Adjust the clearance to approx. 0.1 mm (0.004 in) for used differ-
ential [driven approx. 3,000 km (1864 mile) or more].
4. Install lock pin (1) to pinion mate shaft using the pin punch A.
CAUTION:
• Do not reuse lock pin.
• Make sure that lock pin is flush with differential case.
5. Install speedometer drive gear on differential case.
