(4) Fit the selected shims and O-ring on side bearing
retainer and install them on differential carrier with the
arrow mark on the retainer directed as shown in figure.
CAUTION:
Be careful that side bearing cup is not damaged by
bearing roller.

(6) Measure the crown gear-to-drive pinion backlash.
Set magnet base on differential carrier. Align contact point
of dial gauge with tooth face of crown gear, and move
crown gear while holding drive pinion still. Read value indi-
cated on dial gauge.
Backlash:
0.10 — 0.20 mm (0.0039 — 0.0079 in)
(7) At the same time, measure the turning resistance
of drive pinion. Compared with the resistance when
differential case is not installed, if the increase of the
resistance is not within the specified range, readjust
side bearing retainer shims.
Turning resistance increase:
0.1 — 0.6 N⋅m (1 — 6 kg-cm, 0.9 — 5.2 in-lb)
NOTE:
If measured backlash is not within specified range, repeat
steps (1) thru (7).

Symptom and possible cause Remedy
1. Oil leakage


1Worn, scratched, or incorrectly seated front or side oil seal.
Scored, battered, or excessively worn sliding surface of com-
panion flange.Repair or replace.


2Clogged or damaged air breather. Clean, repair or replace.


3Loose bolts on differential spindle or side retainer, or incor-
rectly fitted O-ring.Tighten bolts to specified torque. Replace O-ring.


4Loose rear cover attaching bolts or damaged gasket. Tighten bolts to specified torque. Replace gasket and apply liquid
packing.


5Loose oil filler or drain plug. Retighten and apply liquid packing.


6Wear, damage or incorrectly fitting for spindle, side retainer
and oil seal.Repair or replace.
2. Seizure
Seized or damaged parts should be replaced, and also other parts should be thoroughly checked for any defect and should be
repaired or replaced as required.


1Insufficient backlash for hypoid gear. Readjust or replace.


2Excessive preload for side, rear, or front bearing. Readjust or replace.


3Insufficient or improper oil used. Replace seized part and fill with specified oil to specified level.
3. Damage
Damaged parts should be replaced, and also other parts should be thoroughly checked for any defect and should be repaired or
replaced as required.


1Improper backlash for hypoid gear. Replace.


2Insufficient or excessive preload for side, rear, or front bear-
ing.Readjust or replace.


3Excessive backlash for differential gear. Replace gear or thrust washer.


4Loose bolts and nuts such as crown gear bolt. Retighten.


5Damage due to overloading. Replace.
4. Noises when starting or shifting gears
Noises may be caused by differential assembly, universal joint, wheel bearing, etc. Find out what is actually making noise before dis-
assembly.


1Excessive backlash for hypoid gear. Readjust.


2Excessive backlash for differential gear. Replace gear or thrust washer.


3Insufficient preload for front or rear bearing. Readjust.


4Loose drive pinion nut. Tighten to specified torque.


5Loose bolts and nuts such as side bearing retainer attaching
bolt.Tighten to specified torque.
