3) Set the gauge inside of the companion flange,
and measure the runout.
Limit of runout:
0.08 mm (0.003 in)
4) If either runout exceeds the limit, move the
phase of companion flange and drive pinion 90°
each, and find the point where the runout will be
within the limit.
5) If the runout exceeds the limit when changing
the phase, replace the companion flange and re-
check the runout.
6) If the runout exceeds the limit after replacing the
companion flange, the drive pinion may be assem-
bled incorrectly or bearing is faulty.

8. General Diagnostic Table
A: INSPECTION
Symptom or trouble Possible cause Remedy
1. Oil leakage(1) Worn, scratched, or incorrectly seated
front or side oil seal. Scored, battered or
excessively wor n sliding surface of com-
panion flange.
Correct or replace.
(2) Clogged or damaged air breather. Clean, repair or replace.
(3) Loose bolts on differential spindle or
side retainer, or incorrectly fitted O-ring.
Tighten the bolts to specified torque.
Replace the O-ring.
(4) Loose rear cover attaching bolts or
damaged gasket.
Tighten the bolts to specified torque.
Replace gasket and apply liquid gasket.
(5) Loose oil filler or drain plug. Retighten and apply liquid gasket.
(6) Wear, damage or incorrect fitting of
spindle, side retainer or oil seal.
Correct or replace.
2. Seizure
NOTE:Seized or damaged parts should be re-
placed, and also other parts should be thor-
oughly checked for any defect and should
be repaired or replaced as required.
(1) Insufficient backlash for hypoid gear. Readjust or replace.
(2) Excessive preload for side, rear or
front bearing.
Readjust or replace.
(3) Insufficient or improper oil used. Replace seized part and fill with speci-
fied oil to specified level.
3. Damage
NOTE:Damaged parts should be replaced, and
also other parts should be thoroughly
checked for any defect and should be re-
paired or replaced as required.
(1) Improper backlash for hypoid gear. Replace.
(2) Insufficient or excessive preload for
side, rear or front bearing.
Readjust or replace.
(3) Excessive backlash for differential
gear.
Replace gear or thrust washer.
(4) Loose bolts and nuts such as hypoid
driven gear bolt
Retighten.
(5) Damage due to overloading. Replace.
4. Noises when starting or shifting
gears
NOTE:
Noises may be caused by differential as-
sembly, universal joint, wheel bearing, etc.
Find out what is actually making noise be-
fore disassembling.
(1) Excessive backlash for hypoid gear. Readjust.
(2) Excessive backlash for differential
gear.
Replace the differential case assembly.
(3) Insufficient preload for front or rear
bearing.
Readjust.
(4) Loose drive pinion nut. Tighten to the specified torque.
(5) Loose bolts and nuts such as side
bearing retainer attaching bolt.
Tighten to the specified torque.
5. Noises when cornering(1) Damaged differential gear. Replace the differential case assembly.
(2) Excessive wear or damage of thrust
washer.
Replace the differential case assembly.
(3) Broken pinion mate shaft. Replace the differential case assembly.
(4) Seized or damaged side bearing. Replace.
6. Gear Noise
NOTE:
Since noises from engine, muffler, trans-
mission, propeller shaft, wheel bearings,
tires, and body are sometimes mistaken for
noises from differential assembly, be care-
ful in checking them. Inspection methods to
locate noises include coasting, accelerat-
ing, cruising, and jacking-up all four wheels.
Perform these inspections according to the
condition of trouble. When listening to nois-
es, shift gears into four wheel drive and
fourth speed position, trying to pick up only
differential noise.
(1) Improper tooth contact of hypoid gear. Readjust or replace hypoid gear set.
(2) Improper backlash of the hypoid gear. Readjust.
(3) Scored or chipped teeth of hypoid
gear.
Replace hypoid gear set.
(4) Seized hypoid gear. Replace hypoid gear set.
(5) Improper preload for front or rear
bearings.
Readjust.
(6) Seized, cut-away or chipped front or
rear bearing.
Replace.
(7) Seized, cut-away or chipped side
bearing.
Replace.
(8) Differential carrier is vibrating. Replace the differential case assembly.

C: CAUTION
Please clearly understand and adhere to the follow-
ing general precautions. They must be strictly fol-
lowed to avoid any injury to the person doing the
work or people in the area.
1. OPERATION
•Wear work clothing, including a cap, protective
goggles and protective shoes during operation.
•Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
•Keep the disassembled parts in order and pro-
tect them from dust and dirt.
•Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly and replacement.
•Be careful not to burn yourself, because each
part on the vehicle is hot after running.
•Use SUBARU genuine grease etc. or equivalent.
Do not mix grease etc. with that of another grade or
from other manufacturers.
•Be sure to tighten fasteners including bolts and
nuts to the specified torque.
•Place shop jacks or rigid racks at the specified
points.
• Apply grease onto sliding or revolution surfaces
before installation.
•Before installing snap rings, apply sufficient
amount of grease to avoid damage and deforma-
tion.
•Before securing a part on a vise, place cushion-
ing material such as wood blocks, aluminum plate,
or shop cloth between the part and the vise.
2. OIL
When handling oil, follow the rules below to prevent
unexpected accidents.
•Prepare container and waste cloths when per-
forming work which oil could possibly spill. If oil
spills, wipe it off immediately to prevent from pene-
trating into floor or flowing outside, for environmen-
tal protection.
•Follow all government and local regulations con-
cerning waste disposal.
