NOTE:
•Assemble in the reverse order of disassembly.
•Check and adjust each part during assembly.
•Use a new gasket.
•Keep the shims and washers in order, so that
they are not improperly installed.

shims, washers and bearings are to be installed.
•Apply gear oil when installing the bearings and
thrust washers.
•Be careful not to mix up the RH and LH bearing
races.
•Replace the oil seal with a new one at every dis-
assembly. Apply grease to the lips when installing
the oil seal.
•Be careful not to mix up the differential oil seal

bearings with collar and washer. Pinion height ad-
justing washer is not affected by this adjustment.
The adjustment must not be carried out with oil seal
inserted.

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)

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.
