(b) Stake

the

differential

case.

INSTALL RING GEAR ON DIFFERENTIAL CASE

(a) Clean the contact surfaces of the differential case and the

threads of the ring gear and differential case.

(b) Heat the ring gear in boiling water.

evaporated, quickly install the ring gear to the differential
case.
HINT: Align the matchmarks on the ring gear and the differen-
tial case.

(d) Tighten 2 of the bolts temporarily so that the bolt holes in the

ring gear and differential case are not misaligned.

NOTICE: The ring gear set bolts should not be tightened until

the ring gear has cooled sufficiently.

INSTALL RING GEAR SET BOLTS

(a) After the ring gear has cooled sufficiently, install 10 new ring

gear set bolts to which thread lock has been applied.

Thread lock:

Part No. 08833–00100, THREE BOND 1360 K or

equivalent.

NOTICE: New ring gear set bolts should be used in every case.

(b) Torque the 10 set bolts uniformly and a little at a time.

INSTALL DRIVE PINION BEARING OUTER RACES AND
ADJUSTING WASHER
HINT: The adjusting washer is used for adjusting the tooth
contact pattern. 42 types of washer with differential thick-
nesses are available.
First fit a washer with the same thickness as the washer
which was removed, then after checking the tooth contact
pattern, replace the washer with one of a different thickness
if necessary.
When removing an adjusting washer, be sure to replace it
with a new one.

(a) Using SST and a press, install a new adjusting washer and

the front bearing outer race.

10. TEMPORARILY ADJUST DRIVE PINION PRELOAD
(a) Adjust the drive pinion preload by tightening the companion

flange nut.
HINT: Using SST to hold the flange, tighten the nut.
SST 09229–55010, 09330–00021

NOTICE: As there is no spacer, tighten the nut a little at a time,

being careful not to overtighten it.

(b) Using SST and a torque wrench, measure the drive pinion

preload.

HINT: For vehicle which have run 8,000 km (5,000 miles) or
less, if the preload value measured disassembly is greater
than the specification for a reused bearing, return the preload
to the same as before disassembly.

11. INSTALL SIDE BEARING OUTER RACE AND ADJUST

WASHER
Using SST and a press, press the outer race and washer.

12. INSTALL DIFFERENTIAL CASE IN CARRIER

Install the drive side bearing in the differential carrier first, as
shown in the illustration, then install the differential case.

13. INSTALL DIFFERENTIAL CARRIER RETAINERS
(a) Using SST and hammer, install the bearing retainer.
