DESCRIPTION AND OPERATION PROPELLER SHAFT ALIGNMENT
Description
The front and rear propeller shafts have non-constant
velocity 'Hooks' 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 sealed.
The rear shaft is fitted with a conventional joint at
gearbox end and the sliding joint sealed with a rubber
gaiter. An SGF rubber coupling is fitted at the
differential end of the shaft.
The front shaft which is shorter than the rear is
'Phased', with the joints at each end, A and B
mis-aligned as shown in RR4199.
The phasing is necessary on the front shaft only to
allow for greater variation in angular changes.
Catalyst vehicles
The front shaft is 'phased' as above but is of solid bar
construction.

FAULT DIAGNOSIS VIBRATION HARSHNESS
1.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, LT230T Transfer Box
- Oil Leaks
For balance of road wheels.See WHEELS AND
TYRES, Repair, Wheel Balancing

REPAIR 18.Press each cup into its respective yoke up to
lower land of circlip grooves. Damage may be
caused to cups and seals if cups pass this point.

bearing cups and circlips as described in
instructions 14 to 19.
21.Fit grease nipples to spider and sliding member.
22.Apply instructions 14 to 19 to opposite end of
propeller shaft.
23.Fit grease nipple and lubricate.
Refit
24.Fit propeller shafts to vehicle and tighten nuts to
47Nm
