1) Adjusting preload for front and rear bearings
Adjust the bearing preload between front and rear
bearings with collar and washer. Pinion height ad-
justing washer is not affected by this adjustment.
The adjustment must not be carried out with oil seal
inserted.
(1) Install the rear bearing race into the differen-
tial carrier using ST1 and ST2.
ST1 398477701 HANDLE
ST2 398477703 DRIFT 2
(2) Using the ST, install the front bearing race to
the differential carrier.
ST 499277200 INSTALLER
(3) Insert the front bearing cone.
NOTE:
Use new front bearing cone.
(4) Measure and record the thickness of pinion
adjust washer.
NOTE:
If tooth contact (drive pinion, hypoid driven gear) is
normal in the inspection before disassembling, ver-
ify that the washer is not deformed, and then re-use
the used washer.
(5) Insert the ST1 into carrier with the pinion
height adjusting washer and rear bearing cone
fitted onto it.
NOTE:
Use new rear bearing cone.
(6) Install the preload adjusting collar & washer,
front bearing cone, collar, companion flange,
and washer & self-locking nut.

(7) Turn ST1 by hand to seat the bearing, and
measure the initial load and initial torque with a
spring scale while tightening the selflocking nut.
Select the preload adjusting washer and collar
so that the specified preload is obtained when
nut is tightened to the specified torque.
NOTE:
•Use a new self-locking nut.
•Be careful not to give excessive preload.
•When tightening the self-locking nut, lock com-
panion flange with ST2 as shown in the figure.
•Measure the preload in direction of tangent to the
flange.

of ST2 and the end surface of ST1 by using a
thickness gauge.
NOTE:
Make sure there is no clearance between the case
and ST2.

(4) Obtain the thickness of pinion height adjust-
ing washer to be inserted from the following for-
mula, and replace the temporarily installed
washer with this one.
NOTE:
Adjust it using the 0 — 3 washers.
T = To + N – 0.05 mm (0.0020 in)
(Example of calculation)
To = 0.15 mm (0.0020 in)
N = 0.1 mm (0.0039 in)
T = 0.15 mm (0.0020 in) + 0.1 mm (0.0039 in) –
0.05 mm (0.0020 in) = 0.2 mm (0.0079 in)
Result: Thickness = 0.2 mm (0.0079 in)
Therefore use part number 32295AA370.
3) Install the selected pinion height adjusting wash-
er on drive pinion, and press the rear bearing cone
into position with ST.

4) Insert the drive pinion into the differential carrier,
and install the preselected bearing preload adjust-
ing collar and washer.
5) Set ST and differential carrier to the press and
install the front bearing cone.

17) Tighten the bolt of lock plate to specified
torque.
Tightening torque:
25 N·m (2.5 kgf-m, 18.1 ft-lb)
18) Recheck the hypoid driven gear to pinion back-
lash.
Backlash:
0.10 — 0.15 mm (0.0039 — 0.0059 in)
19) Checking and adjusting the tooth contact of hy-
poid driven gear
(1) Apply an even coat of red lead on both sides
of three or four teeth on the hypoid driven gear.
Check the contact pattern after rotating the hy-
poid driven gear several revolutions back and
forth until a definite contact pattern appears on
the hypoid driven gear.
(2) When the contact pattern is not correct, re-
adjust.
NOTE:
Be sure to wipe off the red lead completely after the
adjustment is completed.
•Correct tooth contact
Check item: Tooth contact pattern is slightly
shifted towards the toe side under no-load rota-
tion. (When driving it will move toward the heel
side.)
•Face contact
Check item: Backlash is too large.
Contact pattern
Corrective action: Increase thickness of drive pin-
ion height adjusting washer in order to bring drive
pinion close to hypoid driven gear.
