Adjust the bearing preload between front and rear
bearings with collar and washer. Pinion height ad-
justing washer is not affected by this adjustment.

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.

(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.

12) Install the hypoid driven gear to differential
case.
NOTE:
•Tighten diagonally while tapping the bolt heads.
•Set a cushioning such as wooden block, alumi-
num plate or shop cloth between vise and differen-
tial case if the side gear comes into contact with
vise.

CAUTION:
Make sure that the RH and LH oil seals, bearing

(3) Install the differential assembly into differen-
tial carrier in the reverse order of disassembly.
(4) Temporally tighten the side holders RH and
LH in differential carrier to install.

15) Perform the backlash adjustment between the
hypoid driven gear and drive pinion, and preload
adjustment of differential side bearing.
(1) Turn the drive pinion with ST for better fitting
of differential side bearing.

(2) Screw in the side holder LH until light con-
tact is made with ST.

(3) Back off the holder on the hypoid driven
gear side by approx.1 and 1/2 teeth, and tighten
the other side holder by approx. 2 teeth (amount
that the hypoid driven gear is turned back (1
and 1/2) + 1/2 teeth).
[Back off amount of side (hypoid driven gear
side) holder + 1/2 tooth.] This + 1/2 tooth gives
preload.
(4) Temporarily tighten the lock plate.
NOTE:
Turn over the lock plate to shift the holder by 1/2
tooth.
(5) Measure the hypoid driven gear-to-drive
pinion backlash. Set the magnet base on differ-
ential carrier. Align the contact point of dial
gauge with tooth face of hypoid driven gear, and
move hypoid driven gear while holding drive
pinion still. Read the value indicated on dial
gauge.
NOTE:
If measured value of backlash is not within the
specified range, repeat the procedures for pinion
driven gear set backlash adjustment and the differ-
ential side bearing preload adjustment.
Backlash:
0.10 — 0.15 mm (0.0039 — 0.0059 in)
16) Put alignment marks on both the differential
carrier and holder. Remove the holder side at a
time.
Replace them in the original position after inserting
an O-ring and applying grease to the threaded por-
tion.

torque.
Tightening torque:

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.
