REAR AXLE AND FINAL DRIVE
1
DESCRIPTION AND OPERATION DESCRIPTION
The welded steel rear axle casing houses a separate
spiral bevel type differential unit, which is off set to the
right of the vehicle centre line. The differential unit
drives the rear wheels via the axle shafts and fully
floating hubs which are mounted on tapered roller
bearings.
Lubrication
The differential is lubricated with oil and the hub
bearings with grease.The hub bearings are fitted with inner and outer seals.
The outer seals prevent the differential oil mixing with
the hub grease and the inner seals prevent dirt
ingress into the hub.
Ventilation
Ventilation of the hub bearings is through the outer oil
seals and the differential ventilation pipe, which
terminates at a high level.

FAULT DIAGNOSIS FAULT DIAGNOSIS
Complaint - Oil leaks
An external leak of lubrication from the hub seals can
be caused by a faulty internal seal. For example, if the
seals which separate the differential from the hubs are
faulty and the vehicle is operating or parked on an
embankment, oil from the differential may flood one
hub resulting in a lack of lubrication in the differential.
When a seal is found to be leaking check the axle
ventilation system, as a blockage can cause internal
pressure to force oil past the seals.
See 'Description and Operation' for illustrations of oil
seal locations.
When investigating hub seal leaks check the grease
for dilution with oil. Also check the differential oil level,
for signs of metal particles in the oil and the condition
of internal seals.
If the vehicle is driven in deep water with defective oil
seals, water may contaminate the lubricants and raise
the differential oil level, giving a false impression that
the housing has been overfilled.
Do not assume that a high oil level in the
differential is due to over filling or, that a low level
is because of an external leak.
