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:
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.

23) Affix with the attachment clip so that the white
marking of the hose is within the range of Z (87°).
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)
(1) 0 — 1 mm (0 — 0.04 in)

Pipe Assembly
POWER ASSISTED SYSTEM (POWER STEERING)
C: INSPECTION
Check all disassembled parts for wear, damage or other problems. Repair or replace the defective parts as
necessary.
CAUTION:
Although the surface layer materials of rubber hoses have excellent weathering resistance, heat re-
sistance and resistance for low temperature brittleness, they are likely to be damaged chemically by
brake fluid, battery electrolyte, engine oil and automatic transmission fluid and their service lives are
to be very shortened. Wipe off hoses immediately if any of these come into contact with the hoses.
Since resistances for heat or low temperature brittleness are gradually declining according to time
accumulation of hot or cold conditions for the hoses and their service lives are shortening accord-
ingly, it is necessary to perform careful inspection frequently when the vehicle is used in hot weather
areas, cold weather areas and a driving condition in which many steering operations are required in
short time.
Particularly continuous work of relief valve over 5 seconds causes to reduce service lives of the hos-
es, the oil pump, the fluid, etc. due to over heat.

protect it.
8) Use a screw driver to pry the oil seal out.
CAUTION:
Be careful not to scratch the inner surface of
the casing.
D: ASSEMBLY
1) Caution during reassembly
(1) When removing O–rings, oil seals and snap
rings, always replace with new parts.
(2) Thoroughly wash the parts and allow to dry.
Make sure the parts do not come into contact
with cleaning oil or dust.
(3) The reassembly must be performed in a
clean place. Make sure lint or other foreign ob-
jects do not stick to parts.
(4) Cleaning oil tends to remain inside the front
casing. Use compressed air to completely clean
out any remaining cleaning oil.
(5) Make sure the parts are not rusted. Once
the parts are washed and dried, use a specified
hydraulic oil to prevent rust.
(6) Reassemble in the reverse order of removal.
2) At the bearing positions, apply grease to the oil
seal and front casing inner surfaces.
CAUTION:
Make sure the inner surface of the front body is
not damaged.

General Description
TIRE PRESSURE MONITORING SYSTEM (DIAGNOSTICS)
2. General Description
A: CAUTION
1. SRS AIRBAG SYSTEM
Airbag system wiring harness is routed near the
TPM control module.
CAUTION:
•Wiring harnesses of all airbag system are yel-
low. Do not use the electrical test equipment on
these circuits.
•Be careful not to damage the airbag system
wiring harness when servicing the tire pressure
monitoring control module.
2. TIRE PRESSURE MONITORING CON-
TROL MODULE
•If the alteration of tire rotation, the installation po-
sition or the replacement of transmitter is per-
formed, ID registration for the transmitter is
required. TRANSMITTER ID, OPERATION, Subaru Select
Monitor.>
•When adjusting tire pressure indoors in winter,
there is a big temperature difference between the
indoor facilities and outside. Once the car is outside
where the temperature is lower, the air pressure in
the tires will drop, causing the tire pressure warning
light to come on, even if the pressure in the tires
was adjusted to standard values indoors. To avoid
this, it is necessary to adjust the tire pressure to the
high side in consideration of the difference in tem-
perature between inside and outside.
B: INSPECTION
Before performing diagnosis, check the following
item which might affect the quality of the tire pres-
sure monitoring system.
1. TIRE
•Inspect that the tire pressure is within the speci-
fication while the tire is cool. (Refer to Tire Caution
Label.)
•Check the tires for damage or the insertion of for-
eign matters.
2. BATTERY
Check that amount of battery fluid, gravity and volt-
age are within the specifications.
Standard voltage: 12 V or more
Specific gravity: 1.260 or more
