DESCRIPTION AND OPERATION PROPELLER SHAFT
Description
The front and rear propeller shafts have non-constant
velocity type universal joints, with needle roller
bearings. The bearing cups are pre-packed with
lubricant on assembly and a grease nipple is fitted for
servicing as specified, in maintenance section.
Both shafts have Rilsan coated sliding splines to
accommodate the variation in distance between the
axles and transmission. The splines are pre-packed
with lubricant and protected by a rubber gaiter. A
grease nipple is also fitted for servicing requirements.
The front shaft which is shorter than the rear is
'phased', with the joints at each end, A and B
mis-aligned as shown.
The phasing is necessary on the front shaft only to
allow for greater variation in angular changes.

FAULT DIAGNOSIS VIBRATION HARSHNESS
Check that the propeller shaft universal joints and
sliding splines are not siezed or worn and that the
shafts are correctly aligned.
NOTE: In the event that both shafts are
satisfactory, but the vibration/harshness is
still present, the transfer box operation
and balance of the road wheels should be
checked.
For transfer box operation
See TRANSFER
GEARBOX, Fault diagnosis, Transfer Gearbox -

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.
