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.
ST 498427200 FLANGE WRENCH
(2) Screw in the side holder LH until light con-
tact is made with ST.
ST 18630AA010 WRENCH
(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.

17) Tighten the bolt of lock plate to specified
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.

20) If proper tooth contact is not obtained, once
again adjust the drive pinion height and the differ-
ential side bearing preload (already mentioned)
and the hypoid gear backlash.
21) Attach a new gasket, rear cover, and ground
stay to the differential carrier.
Tightening torque:
34 N·m (3.5 kgf-m, 25.1 ft-lb)
22) Using new gaskets, install the rear differential

E: INSPECTION
Wash all the disassembled parts clean, and exam-
ine them for wear, damage or other defects. Repair
or replace the defective parts as necessary.
1) Hypoid driven gear and drive pinion
•If there is evidently an abnormal tooth contact,
find out the cause and adjust until the teeth contact
correctly. Replace the gear if there is an excessive
worn or an incapable adjustment.
•If crack, cutout or seizure is found, replace the
parts as a set. Slight damage of some teeth can be
corrected by oil stone or the like.
2) Side gear and pinion mate gear
•Replace the differential case assembly if cracks,
scoring or other defects are evident on tooth sur-
face.
3) Bearing
Replace if seizure, peeling, wear, rust, dragging
during rotation, noise or other defect is evident.
4) Oil seal
Replace if deformed or damaged, and at every dis-
assembling.
5) Differential carrier
Replace if the bearing bores are worn or damaged.
6) Differential case
Replace if its sliding surfaces are worn or cracked.
7) Companion flange
Replace if the oil seal lip contact surface shows
cracking.
1. HYPOID DRIVEN GEAR BACKLASH
Using a dial gauge, check the backlash of hypoid
driven gear.
Hypoid driven gear backlash:
0.10 — 0.15 mm (0.0039 — 0.0059 in)
If the hypoid driven gear backlash is not within the
specification, adjust the side bearing preload or re-
pair if necessary.
2. TOOTH CONTACT BETWEEN HYPOID
DRIVEN GEAR AND DRIVE PINION
Inspect the tooth contact between the hypoid driv-
en gear and drive pinion. BLY, Rear Differential (VA–type).>
3. COMPANION FLANGE
1) If rust or dirt is attached to the companion flange,
remove them.
2) Set a dial gauge at a companion flange surface
(mating surface of propeller shaft and companion
flange), and then measure the companion flange
runout.
Limit of runout:
0.08 mm (0.003 in)
