1. Rear Differential
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.

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.
