1 General Information
The rear suspension system for MY 2005 VZ Models with a live axle (except AWD), incorporate two multiple leaf spring
assemblies in conjunction with shock absorbers and a stabiliser bar as standard equipment. The rear suspension system
provides support and control of the movement of the rear axle assembly during vehicle motion and when stationary.
AWD Crew Cab models with a live rear axle and leaf springs do not have a stabiliser bar fitted.
The rear suspension system is mounted to the chassis at four locations via the leaf spring shackle mount brackets, the
spring eye bushing mount bra ckets and bolts. Two U-bolts on each side attach the rear axle assembly to each rear leaf
spring retainer bracket.
The natural resistance or tensi on of the leaf springs helps control wind-up or torque reaction of the rear axle assem bly.
The control of rear axle assembly wind-up or torque reaction is also assisted by double action shock absorbers whose
primary function is to provide spring damping. The shock absorbers are mounted between the chassis frame and the rear
leaf spring retainer brackets.
The rear axle assembly bump over-travel, is restricted b y rubber b ump stops mounted to the chassis just above the rear
axle housing tube on each side.
Where fitted, a decoupled stabiliser bar is attached to the re ar axle assembly by two mounting brackets and insulatin g
bushes, while at each end of the stabiliser bar, a link with two ball joints is attached. Each link is attached to the chassis,
using the second ball joint stud.

2 Service Operations
2.1 Service Warnings, Cautions and Notes
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 of these identification marks is present alongside a fastener torque wrench specification, the
recommendation regarding that fastener must be adhered to.
ABS/TC Components
Whenever any component that forms part of the ABS (if fitted) is disturbed during
Service Operations, it is vital that the complete ABS system be checked, refer to
Section 5B ABS/TCS/ESP General Information.
Road Wheels
Whenever a road w heel and/or brake di sc is removed from the vehicle, the relationship of the road
wheel and the disc to the hub MUST be marked with a felt tipped pen or similar, to allow those
parts to be reinstalled in their original positions. This is critical to minimise the brake disc and
road wheel runout dimension.
When reinstalling road wheels, do not use
an impact gun to tighten wheel nuts
unless the impact gun is fitted with a
torque limiter socket (Tool No. AU 534 or
a commercial equivalent). Failure to
correctly tighten w heel nuts to the correct
torque specification and in the correct
order (as shown), may result in a
distorted brake disc, leading to the
development of brake shudder.

The following fasteners MUST be replaced when performin g these operations:
Rear leaf spring shackle attachin g nuts.
Rear leaf spring eye attaching bolt and nut.
Leaf spring centre bo l t attaching nut.
Rear shock absorber lower mounting attaching bolt.

Remove
1 Remove the rear wheel covers, then mark the relationship of the road wheel to one of the wheel studs.
2 Loosen, then remove the road wheel attaching nuts, working in a 'star' pattern. Refer to
2.1 Service Warnings, Cautions and Notes in this Section, for detailed information. Remove the road wheel.
3 Using a floor jack under the centre of the rear axle
assembly (1).
4 Raise the rear of vehicle, then place safety stands
under the rear chassis (2) on both the left-hand an d
right-hand sides to support the weight of the vehicle.
5 With the floor jack still under the centre of the rear axle
assembly, take-up the weight of the rear axle housing,
while observing the leaf springs and sh ackles to gain
the desired height to relieve any spring tension.
6 Place two more safety stands at each side to support
the rear axle assembly weight.
7 Remove the floor jack.

Disassemble
1 Using a felt tipped pen or similar, draw a line down the side of the spring, marking each leaf. This will assist in the
correct orientation of the leaves on reassembly.
2 Clamp the leaf spring assembly in a vice fitted with soft jaws, in an area close to the centre bolt. Alternatively a
G-clamp may be used.
3 Remove the leaf spring assembly centre bolt retaining nut (6).

3 Diagnosis
3.1 Checking and Testing Shock Absorbers
Preliminary Checks
1 Before proceeding with the removal of shock absorb er assemblies, it is go od practise to check and make sure the
noise is not coming from some other source.
2 Conduct a visual inspection of all shock absorber components and other rear suspension related components,
checking for anything that may appear unusual.
3 Check the torque of all attaching fasteners for tightness an d check all mounting bushes for alignment. If the bushes
are worn, loose fitting or misaligned, they must be replaced.
Testing Shock Absorber Action
:
The following test is for non-gas pressurised
shock absorbers.
1 Using a suitable vice equipped with soft jaw’s (1),
support the shock absorber (2) by its lo wer mount.
2 Slowly pump the shock absorber up an d down its full
stroke at least six times to prime the internal valves of
the shock absorber.
3 Move the shock absorber up and down at various
rates of speed while monitoring the resistance. The
resistance should be consistent throughout both
stokes and there should be no slack spots. If slack
spots are detected this indicates either a lack of oil or
the internal valves are defective.
NOTE:
It is normal for a hissing (orifice swish) noise to
be detected during shock abs orber testing.
Figure 4A2 – 15
4 The following conditions are considered outside the normal functio n parameters and replacement is recommended:
a A skip or lag at reversal of the stroke mid way through.
b A seize (except at the extreme end of travel).
c A noise such as a grunt or squeal after the completing one full stroke in both directions.
d A clicking noise at fast reversal of the stroke.
e Fluid leakage.
