3) Install propeller shaft to joint flange aligning match marks
and torque flange nuts to specification. Apply thread lock
cement to thread part of bolt if reused.

Unit Repair
Disassembling Unit
1) Hold differential assembly securely and put identification
marks on differential side bearing caps (6).
2) Take off differential side bearing lock plates (4) and differen-
tial side bearing caps (6) by removing their bolts and then
take out bearing adjusters (5), side bearing outer races and
drive bevel gear with differential case.
3) Remove drive bevel gear (hypoid gear), differential gears,
differential pinions and pinion shafts.
a) With aluminum plates (2) placed on vise first, grip differen-
tial case with it and remove drive bevel gear (hypoid gear)
(3) by removing its bolts (1).

b) Make mating marks (1) on drive bevel pinion and compan-
ion flange.
c) Remove companion flange from drive bevel pinion. Use
special tool if it is hard to remove.

(F) : 09913-65135
d) Remove drive bevel pinion with rear bearing, shim and
spacer from carrier.
If it is hard to remove, screw an used nut into drive bevel
pinion and hammer on that nut with a plastic hammer but
never directly on drive bevel pinion.
e) Remove drive bevel pinion rear bearing (2) by using bear-
ing puller (3) and press. CAUTION:
Don't make mating mark on the coupling surface of the
flange.

6) Using a hammer and brass bar (1), drive out front bearing
outer race with bearing (2) and oil seal (3).
7) Drive out rear bearing outer race in the same way as in the
step 6).
Component Inspection
•Check companion flange for wear or damage.
•Check bearings for wear or discoloration.
•Check differential carrier for cracks.
•Check drive bevel pinion and drive bevel gear for wear or cracks.
•Check differential gears, pinions and pinion shafts for wear or damage.
•Check differential gear spline for wear or damage.
Sub-Assembly Adjustment and Reassembly
Judging from faulty conditions noted before disassembly and
what is found through visual check of bearing and gear tooth etc.
after disassembly, prepare replacing parts and proceed to reas-
sembly according to procedures as described below.
CAUTION:
Drive bevel gear and pinion must be replaced as a set
when either replacement becomes necessary.
When replacing taper roller bearing, replace as inner
race & outer race assembly.

Differential case
1) After applying differential oil to differential gear (4), pinions
(5), pinion shafts (6), thrust washer (2) and spring washer
(1), install them in differential right case (3).
For correct installing direction of thrust washer (2) and spring
washer (1), refer to the figure.
2) When installing pinion shaft No.2 (2) (shorter) into differential
case and pinion, insert its “a” side into pinion joint (1).
3) Check differential pinion gear (1) for smooth rotation.
