2 Service Operations
ATTENTION
All front suspension fasteners are important attaching parts as they affect the performance of vital
components and/or could result in major repair expense. Where specified in this Section, fasteners MUST be
replaced with parts of the same part nu mber or a GM app roved equivalent . Do not use fastene rs of an in ferior
quality or substitute design
Torque values must be used as specified during reassembly to ensure proper retention of all front
suspension 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.
2.1 Service Notes and Cautions
Road Wheels
• Whenever a road wheel is removed from or installed to any MY 2006½ VZ Series vehicle, it MUST
be done in accordance with the procedure provided in Section 10 Wheels and Tyres.
• Whenever a road w heel is removed from the vehicle, the relationshi p of the road wheel 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 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.
Road wheel attaching nut
torque specification...................................110 – 140 Nm
Figure 3A – 2
ABS Components
• Whenever any component that forms part of the ABS, is disturbed during Service Operations, it is
vital that the complete ABS system be checked, refer to Section 5B ABS.
Page 3A-4
Front Suspension Page 3A – 5
2.2 Jacking Precautions
When raising the front of the vehicl e with a jack (1), the jack
should be placed under the centre of the front crossmember
(2). The weight of the vehicle MUST NOT be lifted under the
control arms.
When the vehicle is raised on the jack, it must be firmly
supported on safety stands located under the frame side
members before any work is attempted. If a vehicle is not
correctly supported by safety stands, serious injury can
result if the vehicle should slip off the jack.
For further information relating to the location of jacking and
support points, refer to Section 0A General Information.

2.4 Suspension and Trim Height, Check
• Good judgement must be exercised before
replacing a spring or springs from a
vehicle whose height is within the limits
quoted.
• Even if a vehicle's dimensions should
prove to be slightly outside these
tolerances, the vehicle could well be in a
serviceable condition.
• Spring replacement under conditions of
excessive weight due to non-standard
fittings, undercoating, road dirt, etc; will
assist very little in restoring the vehicle to
its specified height.
The suspension and trim height dimensions for RWD Crewman vehicles, are provided in 3 Specifications in this Section.
The dimensions are for a new vehicle built to standard specification a nd are only intended as a guide when checking
suspension and trim height dimensions at no rmal curb weight.
Preliminary Inspection
The following procedure sh ould be followed before checking an y suspension or trim height.
1 Vehicle curb weight is defined as:
• Tyre pressures are to specification.
• Fuel tank is full – add additional weight in the rear compartment to compensate if necessary.
• All fluids are at the specified levels.
• Spare tyre is included.
• Tyre and wheel rim sizes are to specification.
• Vehicle contains no passengers.
2 Accumulated dirt, distance travelled, etc., must also be taken into consideration when checking vehicle heights.
3 Vehicle must be on a level surface.
4 It must be confirmed that the vehicle has not been subjected to accident d amage.
NOTE
It is normal for the vehicle to sit approximately 4
mm lower on one side, because of the vehicle's
battery weight.
Page 3A-9
Front Suspension Page 3A – 10
Procedure
1 Push the vehicle up and down several times at the front bumper bar with a decreasing force and then gently
remove hands, allowing vehicle to settle on its own.
2 Carry out front suspension and trim height check, at ‘A’ and ‘C’ respectively; refer to Figure 3A–8.

4 Ground Level
3 Push the vehicle up and do wn several times at the rear with a decreasing force and then gently remove hands,
allowing vehicle to settle on its own.
4 Carry out vehicle rear suspension and trim height check, at ‘B’ and ‘D’, respectivel y; refer to 3A–8.
Front and Rear Suspension Height Comparison
1 When checking a vehicle's suspension height, the following tolerances must also be taken into account, before any
spring is replaced. Compare the front and rear suspension height measurements between:
• Front to rear.
• Side to side
Ride Height Variations from Specification
Front to Rear.....................................................± 20 mm
Side To Side ..................................................... ± 10 mm
Normal Spring Settling........................................ ± 5 mm
NOTE
Ride height variatio n may also be due to any one
or a combination of the follo wing:
• Spring seat location on the suspens ion/body.
• Incorrect springs. Check spring identification
against the table shown in 3 Specifications in
this Section.
• Non-standard, additional vehicle weight, such
as a tow bar and/or after-market LPG fitment.
• Any combination of the above.
