6) Select adjusting shim(s) (2) closest to calculated value from
among following available sizes and put it in place and then
press-fit rear bearing (1).

7) With new pinion spacer (3) inserted as shown in the figure,
install front bearing (5) to differential carrier (4).
8) Using special tool and plastic hammer, drive oil seal (2) into
differential carrier (1) till it becomes flush with carrier end.
Then apply grease “A” to oil seal lip.
“A” : Grease 99000-25010

NOTE:
Make sure to use new spacer for reinstallation.

9) While tightening flange nut gradually with special tool and
power wrench (4 - 10 magnification) (1), set preload of pinion
to specification.
Pinion bearing preload
: 0.9 – 1.7 N·m (9.0 – 17.0 kg-cm, 7.8 – 14.7 lb-in.)
Spring measure reading with special tool
: 16 – 30 N (1.6 – 3.0 kg, 3.5 – 6.6 lb)
Special tool
(C) : 09922-76560
(J) : 09922-66021 NOTE:
Before taking measurement with spring balance (3) or
torque wrench (4), check for smooth rotation by hand.
On measuring preload, rotate the drive bevel pinion
about 1 rotation per 2 seconds.
Be sure to tighten gradually and carefully till specified
starting torque is obtained. Turning back overtightened
flange nuts should be avoided.

Assembling Unit
1) Place bearing outer races on their respective bearings.
Used left and right outer races are not interchangeable.
2) Install case assembly in carrier.
3) Install side bearing adjusters on their respective carrier,
making sure adjuster are threaded properly.
4) Align match marks (1) on cap and carrier. Screw in 2 side
bearing cap bolts 2 or 3 turns and press down bearing cap
by hand.
5) Tighten cap bolts (provisional torque).
Tightening torque
Bearing cap bolt (Provisional torque) (a) :
15 N·m (1.5 kg-m, 11.0 lb-ft)
6) Tighten both bearing adjusters (2) so as to obtain specified
gear backlash and at the same time, obtain preload of side
bearing.
Standard backlash
: 0.13 – 0.18 mm (0.005 – 0.007 in.)
Special tool
(A) : 09930-40120
(B) : 09930-40113
(C) : 09900-20701
NOTE:
If bearing cap does not fit tightly on carrier, side bearing
adjuster is not threaded properly. Reinstall adjuster.
NOTE:
Be sure to apply measuring tip of dial gauge at right
angles to convex side of tooth.
As a practical measure the following would be recom-
mended to obtain specified backlash and side bearing
preload at the same time.
–Obtain specified backlash by turning both adjusters
inward lightly.
–Tighten both adjusters further by one notch at a
time.
Measure at least 4 points on drive bevel gear periph-
ery.

7) Measure preload of pinion bearing with spring balance (1) or
torque wrench (2) and check composite preload of pinion
bearing and side bearing.
Composite preload of pinion bearing and side bearing
: 1.1 – 2.0 N·m (11.0 – 20.0 kg-cm, 9.5 – 17.4 lb-in.)
Spring measure reading with special tool
: 19.5 – 35.5 N (1.95 – 3.55 kg, 4.30 – 7.83 lb)
Special tool
(D) : 09922-76560
8) Torque bearing cap bolts (2) to specification and install bear-
ing lock plates.
Tightening torque
Lock plate bolt (b) : 12 N·m (1.2 kg-m, 9.0 lb-ft)
Bearing cap bolt (c) : 85 N·m (8.5 kg-m, 61.5 lb-ft)
9) As final step, check gear tooth contact as follows.
a) After cleaning 10 drive bevel gear teeth, paint them with
gear marking compound evenly by using brush or sponge
etc.
b) Turn gear to bring its painted part in mesh with drive bevel
pinion and turn it back and forth by hand to repeat their con-
tact.
c) Bring painted part up and check contact pattern, referring
to following chart. If contact pattern is not normal, readjust
or replace as necessary according to instruction in chart. NOTE:
Before taking measurement with spring balance (1) or
torque wrench (2), check for smooth rotation by hand.
On measuring preload, rotate the drive bevel pinion
about 1 rotation per 2 seconds.
3. Universal joint flange
4. Socket with adapter
1. Lock plate bolt
NOTE:
Be careful not to turn drive bevel gear more than one full
revolution, for it will hinder accurate check.

TOOTH CONTACT PATTERN DIAGNOSIS AND REMEDY
NORMAL
HIGH CONTACT
Pinion is positioned too far from the center of drive
bevel gear.
4) Increase thickness of pinion height adjusting
shim and position pinion closer to gear center.
5) Adjust drive bevel gear backlash to specifica-
tion.
LOW CONTACT
Pinion is positioned too close to the center of drive
bevel gear.
1) Decrease thickness of pinion height adjusting
shim and position pinion farther from gear cen-
ter.
2) Adjust drive bevel gear backlash to specification.
If adjustment is impossible, replace differential carrier.
1) Check seating of bevel gear or differential case.
(Check bevel gear for runout).
2) If adjustment is impossible, replace drive bevel gear & pinion
set or differential carrier.
Replace drive bevel gear & pinion set or differential case.

10) Upon completion of gear tooth contact check in Step 9),
caulk flange nut (2) with caulking tool (1) and hammer.
