Symptom and possible cause Remedy
4. Broken differential (case, gear, bearing, etc.)
Abnormal noise will develop and finally it will become impossible to continue to run due to broken pieces obstructing the gear
revolution.
(a) Insufficient or improper oil Disassemble differential and replace broken components and
at the same time check other components for any trouble,
and replace if necessary.
(b) Use of vehicle under severe conditions such as excessive
load and improper use of clutchReadjust bearing preload and backlash and face contact of
gears.
(c) Improper adjustment of taper roller bearing Adjust.
(d) Improper adjustment of drive pinion and hypoid driven
gearAdjust.
(e) Excessive backlash due to worn differential side gear,
washer or differential pinionAdd recommended oil to specified level. Do not use vehicle
under severe operating conditions.
(f) Loose hypoid driven gear clamping bolts Tighten.
5. Differential and hypoid gear noises
Troubles of the differential and hypoid gear always appear as noise problems. Therefore noise is the first indication of the
trouble. However noises from the engine, muffler, tire, exhaust gas, bearing, body, etc. are easily mistaken for the differential
noise. Pay special attention to the hypoid gear noise because it is easily confused with other gear noises. There are the
following four kinds of noises.
(1) Gear noise when driving: If noise increases as vehicle speed increases it may be due to insufficient gear oil, incorrect
gear engagement, damaged gears, etc.
(2) Gear noise when coasting: Damaged gears due to maladjusted bearings and incorrect shim adjustment
(3) Bearing noise when driving or when coasting: Cracked, broken or damaged bearings
(4) Noise which mainly occurs when turning: Unusual noise from differential side gear, differential pinion, differential pinion
shaft, etc.
(a) Insufficient oil Lubricate.
(b) Improper adjustment of hypoid driven gear and drive
pinionCheck tooth contact.
(c) Worn teeth of hypoid driven gear and drive pinion Replace as a set.
Readjust bearing preload.
(d) Loose roller bearing Readjust hypoid driven gear to drive pinion backlash and
check tooth contact.
(e) Distorted hypoid driven gear or differential case Replace.
(f) Worn washer and differential pinion shaft Replace.
