1 General Information
The propeller shaft assembly is a two piece tubular design, incorporating a sealed for life centre support bearing. The
centre support bearing is a fully sealed ball bearing, mounted in a reinforced rubber cup. This centre bearing rubber cup
is supported in a cup guide and attache d to a carrier, which is bolted to the vehicle underbod y brace. Should a specific
tow bar package be fitted, a heat shield may also be fitted to the centre bearing carrier. No periodic servicing of the
centre bearing nor any u niversal joint, is required.
For those MY2005 WL vehicles with the GEN III V8 engine and 4 speed 4L60-E automatic transmission, servicing of the
centre bearing is not possible. The reason is that the interference fit of the splined joint between the front and rear
propeller shaft halves is such that special tools and high press forces are required to separate the two shafts. As this
operation would also re quire the re-balancing of the propeller shaft assembly, the centre bearing assembly and/or slinger
are also non-serviceable.
On those MY2005 WL vehicles fitted with the V6 engine and the 5 speed 5L40-E automatic transmission however, the
centre bearing and boot are s erviceable items.
Front Coupling Joint: While al l propeller shafts have a rubber coupling in this location, dep endent upon the transmission,
the coupling may be attached to the transmission output shaft flange by a bolt and nut (V6 5L4 0-E – automatic
transmission) or by being bolted to a slip yoke that is splined to the output shaft (GEN III V8 – 4L60-E automatic
transmission).
Centre Universal Joint: This is a conventional cross type universal joint (Hooke’s joint) mounted behind the centre
bearing. The cross t ype universal joint type is non-serviceable, as the bearing cups are set and retained by staking. This
requires sophisticated equi pment to ensure concentricity of the installed universal joint.
Rear Coupling Joint: The rear coupling is fixed to the rear final drive pinion flange by three, T orx headed special thread
formed bolts.

2 Service Operations
ATTENTION
All fasteners are important attaching parts as they affect the performance of vital components and/or could
result in major repair expense. W here specified in this Section, fasteners MUST be replaced w ith parts of the
same part number or an approved equivalent. Do not use fasteners o f an inferior quality or substitute design.
Torque values must be used as specified during reassembly to ensure proper retention of all components.
Throughout this Section, fastener torque wrench specifications may be accompanied with the following
identification marks:
Fasteners must be repl aced after loosening.
Vehicle must be at curb height before final tightening.
Fasteners either have micro encapsulated sealant applied or incorporate a mechanical thread lock and
should only be re-used once. If in doubt, replacement is recommended.
If one or more of these identification marks is present alongside a fastener torque wrench specification, the
recommendation regarding that fastener must be adhered to.
2.1 Propeller Shaft
Remove
1 Raise the vehicle and suppor t in a safe manner. Refer to Section 0A General Information for location of jacking and
support points.
2 To provide access to the propeller shaft fasteners, it is recommend ed that the intermediate exhaust pipe,
intermediate and rear muffler assemblies be removed. For information regarding the removal and installation
procedures for these components, refer to Section 8B Exhaust System.
Front Coupling Attached to the Transmission Output Flange
A number of different methods of attaching
the front coupling to the transmission output
flange may be observed:
Hexagon headed bolts into threaded
flange holes. With this method, the output
flange threads are of the 'Spiralock' form
that can only be loosened/tightened a
maximum of ten times. Because of the
safety factor involved, if the complete
vehicle service history is not known, then
both the flange and the bolts MUST be
replaced on reassembly.
Studs installed into the transmission
output flange facing rearward, with the
flange being secured by nuts.
Hexagon headed bolts and nuts. Figure
4C1 – 2 shows this method.
Rear Propeller Shaft and Universal Joints Page 4C1 – 5
Page 4C1 – 5
NOTE
If the reason for removing the propeller shaft is
not related to the front rubber coupling, then it is
recommended that the three bolts and nuts
securing the propeller shaft to the front coupling
be removed, leaving the coupling attached to the
transmission output shaft flange.
Release the park brake to relax any ‘wind-up’
in the flexible rubber coupling. Otherwise,
when the propeller shaft bolts are released
from the final drive pinion flange, personal
injury may result.
3 Select the Park position with the transmission selector lever.
4 To enable the propell er shaft to be reinsta lled in the
original position relative to the transmissi on output
shaft flange, use a felt tipped pen or similar t o ide ntify
the relationship (‘A’) of the t wo components.
5 Using suitable socket equipment, loosen the three
bolts (2) and nuts (3) and securing the front coupling
(1) to the transmission output flange
6 With the transmission shift lever in the Neutral position
and the park brake released, remove the three Torx
headed bolts.
Figure 4C1 – 2
7 To enable the propell er shaft to be reinsta lled in the
original position relative to the final drive pinion flange,
use a felt tipped pen or similar to identify the
relationship (‘A’) of the two components.
8 With the transmission in the Park position, check that
the park brake is firmly applied.
9 Use Torx socket K04425E20 or a commercially
available E20 Torx equivalent to loosen the three Torx
headed bolts (1) securing the propeller shaft rear
rubber coupling (2) to the pini on flange (3).
10 Release the park brake to relieve any torque loading
on the rubber coupling, then remove the three Torx
headed bolts (1)

11 Remove the two centre bearing carrier (1) to
underbody reinforcement bolts (2).
12 While supporting the centre beari ng section, slide the
propeller shaft assembly forward to disengage from
the final drive pinion support pin, then lower the
assembly at the rear, sliding rearward to disengage
the front coupling.
13 Remove the propeller shaft assembly from the vehicle.
Figure 4C1 – 4
For WL Models with a Sliding Front Yoke
14 After completing all Steps except 4 to 6 inclusive, slide the propeller shaft assemb ly rearward to disengage the front
yoke from the transmission output shaft splines. Durin g this process:
a Locate a clean drain tray under the rear of the transmission to catch any spilled lubricant when the propeller
shaft is removed.
b Take care to protect the outer diameter of the front yoke. Nicks or abrasions will damage the transmission
extension seal during reassembly and result in subsequ ent lubricant leakage from this area.
c Insert a suitable plug in the end of the transmission re ar extension to prevent loss of transmission lubric ant.
Reinstall
Reinstallation is the reverse of removal procedures, except for the following items:
For WL Models with Front Coupling Attached to the Transmission Output Flange
