b) Make mating marks (1) on drive bevel pinion and
companion flange.
CAUTION
!
Do not make mating mark on the coupling
surface of the flange.
c) Remove flange (2) from drive bevel pinion. Use
special tool if it is hard to remove.
Special tool
(A): 09913–65135
(B): 09925–88210
d) Remove drive bevel pinion (1) with rear bearing,
shim and spacer from carrier.
If it is hard to remove, screw an used nut (2) into
drive bevel pinion and hammer (3) on that nut
with a plastic hammer but never directly on drive
bevel pinion.
e) Remove drive bevel pinion rear bearing (2) by
using bearing puller (3) and hydraulic press.
CAUTION
!
To avoid rear bearing from being damaged,
support it at flat side of bearing puller.

12) Drive out rear bearing outer race (1) in the same
manner as Step 11).
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 reassembly according to
procedures as described.
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 and outer race
assembly.
1) For press-fitting drive bevel pinion bearing outer
races, use special tools and press as shown in the
figure.
Special tool
(A): 09924–74510
(B): 09925–14520
(C): 09913–75510
2) After applying differential oil to differential gear (4),
pinions (5), pinion shaft (6), pinion washer, 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.
3) Check differential pinion gear (1) for smooth rotation.
4) Put drive bevel gear (3) on differential case (1) and
fasten them with bolts (2) by tightening them to
specified torque. Use thread lock cement for bolts
(2).
CAUTION
!
Use of any other bolts than that specified is
prohibited.
“A”: Thread lock cement 99000–32110 (Thread
Lock Cement Super 1322)
