ATTENTION
HSV vehicles are equipped with a Supplemental Restraint System (SRS). An SRS consists of seat belt pre-
tensioners (fitted to all front seats), a driver’s-side air bag, a passenger’s-side air b ag and left and right hand
side air bags. Refer to CAUTIONS, Section 12M, in Volume 12 of the Holden VYII series Service Manual before
performing any service operation on or around SRS components, the steering mechanism or wiring. Failure
to follow the CAUTIONS could result in personal injury or unnecessary SRS system repairs.

1 Purpose
The purpose of this section is to provide information on the front and rear suspension assemblies fitted to HSV VYII
models. The information is designed to supplement the information contained in the Holden VYII Service Manuals, and
details are given where differences occur between the HSV models and standard Holden models. A series of instruction
drawings describe the design changes and indicate specific part numbers, fitting instructions and relevant notes for
vehicle servicing.
NOTE
If specific technical data on a HSV model is not
contained in this supplement, obtain data for that
model from the relevant Holden VYII series
Service Information Supplement. References are
made throughout this section to Holden Service
Manuals, to assist in providing information for
specific service operations.
When hoisting (or jacking) HSV models,
ensure that the liftin g head of the hoist lifts on
the chassis before the arm of the hoist
contacts the side-skirt

2 Front Suspension
2.1 General
The front suspension assembly fitted to all HSV VYII models is based on the Holden ‘MacPherson Strut’ design. All HSV
front suspension struts are gas pressurised and Luxury and Grange struts have Monroe Sensatrac. This basic assembly
(and the rear assembly) is then modified by HSV to provide a suspension system more suited to the requirements of the
HSV vehicle. That is, Performance and Sport suspension systems are fitted to sport and performance type vehicles, and
Luxury suspension systems satisfy the requirements of the luxury sedans. A summary of these suspension systems and
their Standard (S) and Optional (O) applications is contained in the following paragraphs:

2.3 Service Operations
Service front suspension assemblies fitted to HSV models in accordance with the relevant Holden VYII Series Service
Information. Additional service requirements for specific HSV suspension assemblies are detailed in succeeding
paragraphs.
SAFETY AND CAUTIONARY NOTE FOR
VEHICLES EQUIPPED WITH ABS
Whenever any component that forms a part of
the ABS is disturbed, it is vital that the
complete ABS system is checked. Refer to
Section 5B – ABS & ETC of the Holden VYII
Service Information.
The tyre life of high performance low-profile tyres fitted to HSV VYII vehicles is very sensitive to the toe-in setting of the
front suspension. It is crucial therefore, that care is taken to set the toe-in accurately to the correct specification.
The front wheel alignment specification for VYII vehicles is:
VYII
Toe-in
Degrees Total 0°10' ± 0°10'
Degrees Per Wheel 0°05' ± 0°5'
Camber -0°30' ± 0°20'
Caster 7°45' ± 1°15'
The toe-in specification is deliberately quoted as an angle because wherever possible toe-in should be measured in
degrees.
Wheel Alignment Machine Calibration
(From Holden Service Bulletin November 1993)
Investigation of front wheel alignment complaints has revealed a number of dealers with alignment machines incorrectly
calibrated for the vehicle/s being checked. This situation arises because of two basic conventions for measuring toe-in;
Measured across a 14"rim as if tyre is not fitted, and
Measured across 28" tyre. In reality, few modern tyres have a 28"outside diameter, but this standard was developed
when larger tyres were used.
The 28"standard is a carryover from the days when toe-in was measured by jacking the front wheels off the ground,
spinning them, and scribing a reference line on each tread. After settling the vehicle down, the toe-in could then be
measured directly from the tyres with a ‘trammel bar’. However, some manufacturers specify toe-in as if the trammel bar
was placed at the wheel rim diameter, nominally 14" Setting toe-in using the wrong convention for the wheel alignment
machine will cause the actual toe-in to be either TWICE or HALF as much as the specification.
NOTE
IF IN DOUBT, SET TOE-IN USING DEGREES,
AS THE ANGLE IS UNAFFECTED BY THE
DIAMETER OF THE WHEELS USED.
Suspension Page C-7
Page C-7
How To Check Your Machine
Check with the manufacturer of your equipment if unsure of which standard your machine uses to display toe-in. If
unable to establish this, or if your machine appears to be inaccurate, check the machine as follows:4
• Fit properly inflated 15"wheels and tyres to the front of a VP or VR Commodore. Jack the car, spin the wheels and
scribe a line at the middle of each tyre Set the vehicle on the alignment machine and set toe-in to 10mm (5mm per
wheel).
• Measure toe-in at rear of tyres and then at front of tyres with a ‘trammel bar’. If the front distance is less than the
rear distance, you are measuring the toe-in correctly. Compare the measured toe-in to the following table to assess
your machines calibration.
MEASURED TOE-IN RESULT
7 to 11 mm Machine reads @28"
16 to 22 mm Machine reads @ 14"
OTHER CALIBRATE MACHINE
NOTE
The above figures are correct for a 205/65/15
tyre, being a 25"diameter.

4 Rear Suspension - Luxury
(Incorporating Automatic Level
Ride)
4.1 General Description
The Level Ride system fitted to HSV VYII Senator and Senator Signature models is the same as the Holden Level Ride
system with the exception of the rear shock absorbers and the Level Ride sensor link, which are HSV components. The
information in this section is designed to supplement the information contained in the Holden VYII service information and
details are given where differences occur between the HSV models and standard Holden models.
A series of instruction drawings describe the design changes and indicate specific part numbers, fitting instructions and
relevant notes for vehicle servicing.
Automatic Level Ride is fitted HSV VYII Senator and Senator Signature models. Automatic Level Ride is an
electronically controlled self levelling system that maintains the vehicle at a constant trim height, independent of load.
This feature uses a specifically designed electronic sensor, fixed to the rear crossmember on the right hand side (see
Drawing 04I-020005), which controls an electric motor driving a single cylinder air compressor, and an exhaust air
solenoid valve. The compressor supplies the necessary pressure to operate the Air Shock Absorbers via "snap on" air
lines. The Air Shock Absorbers assist the rear springs in supporting the vehicle body under all loads.
The sensor has an integrated electronic controller that is programmed to adjust ride height only when necessary, ignoring
sudden changes, as experienced on bumpy roads. The design of the system maintains trim at all times provided the
battery is connected. As a safeguard to prevent the battery being flattened, an electronic timer switches off the
compressor if it runs for a prolonged period (i.e. due to an air leak in the system).
The compressor assembly includes a maximum pressure release valve and an air drier. All air entering or exhausting the
system flows through the dryer, which has an internal minimum pressure retention valve preventing the Air Bag,
surrounding each Shock Absorber, from completely exhausting independent of the sensor controlled exhaust valve.
A number of benefits result from the level ride feature. These include headlamp aim and rear view mirror adjustment
being maintained independent of load, as well as ensuring the rear wheel camber and toe-in are held at the optimum
positions to minimise tyre wear. An additional major benefit is obtained from supplementary design changes that can be
made to spring and damper rates for improved ride quality at all loading conditions with minimum compromise to
handling. These changes are possible since the suspension does not have to be sufficiently stiff to absorb road impacts,
while supporting maximum vehicle load.
Electrical power to operate the Level Ride system is supplied by a separate harness except the Senator Signature model
which uses the main integrated wiring harness and a short ‘patch harness.’
Rear suspension components fitted to HSV vehicles are similar to Holden VYII and details are given where differences
occur. A series of instruction drawings describe design changes and indicate specific part numbers, fitting instructions
and relevant notes for servicing.
Suspension Page C-14
Page C-14
4.2 System Operation
Activation
The sensor's actuating arm is attached to the lower control arm via a connecting link (See Drawing 04I-020005). Before
any activation can occur the actuating arm must remain in either the intake or exhaust zone for a continuous 17 to 20
seconds.
The time delay prevents the compressor or exhaust valve from activating when the vehicle encounters sudden bumps.
Another stability feature is a designed "Deadband". The Deadband helps to minimise hunting by deactivating the
compressor and solenoid when the vehicle trims into or onto one of the Deadband edges. Refer to Figure C-2 for details
on rear suspension trim heights and Deadband.
Loaded Vehicle
When the vehicle is loaded, the vehicle body moves downward into the intake zone, causing the actuating arm to move
upwards. After 17 to 20 seconds, the sensor relieves compressor head pressure by briefly activating the compressor
relay. The compressor starts and pressurises the air shock absorbers until the vehicle body aligns with the bottom edge
of the Deadband, at which point the compressor stops.
Unloaded Vehicle
When the vehicle is unloaded, the vehicle body moves upward into the exhaust zone, causing the actuating arm to move
downwards. After 17 to 20 seconds, the sensor activates the exhaust relay. The exhaust solenoid activates and vents
pressure from the air shock absorbers until the vehicle body aligns with the top edge of the Deadband, at which point the
solenoid deactivates.
Deactivation
The compressor and exhaust solenoid operations are monitored and controlled by individual but interconnected timers.
The timers deactivate specific trimming operations under the following conditions:
a. If the compressor runs for a cumulative time of more than four-and-a-half minutes, the compressor timer deactivates
all system operations.
b. If the exhaust solenoid is active for a cumulative time of more than four-and-a-half minutes, the solenoid timer
deactivates the solenoid.
NOTE
The sensor timers must be reset before any
further operation can take place. The VYII
system is reset after each ignition cycle ON, OFF
for one minute, ON.

Suspension Page C-22
Page C-22
5.2 Service Operations
The differential oil must be changed at 45,000 km intervals. Use synthetic hypoid gear oil to HN2040 such as ‘Mobilube
SHC 80W-140 ID’.
The viscous coupling cartridge assembly is a sealed unit and must be replaced as a complete assembly if required.
General service operations are the same as those described in the Holden VS series Service Manual however, to
determine if the Hydratrak coupling cartridge is faulty, undertake the following torque check. The Hydratrak rear axle
assembly is covered by the current Axle Warranty Changeover agreement between GMHAL and BTR Engineering (refer
GMHA Dealer Bulletins).
Torque Check
i. Place transmission in neutral with engine turned 'OFF'.
ii. Jack up one rear wheel, then release park brake lever to fully 'OFF' position. Support vehicle body on a safety
stand.
iii. Remove centre cap (alloy wheels).
iv. Mark relationship of road wheel to axle flange. Remove road wheel attaching nuts and remove wheel.
v. Remove caliper attaching bolts and remove caliper from mounting, refer Section 5 BRAKES in the Holden
Commodore Service Manual No. 2. Support caliper on a wire hook. Remove brake disc.
DO NOT ALLOW CALIPER TO HANG BY
BRAKE HOSE
vi. Using a torque wrench in conjunction with adaptor, Tool No. 4A48, and torque wrench adaptor E6662B, rotate axle
shaft in forward direction. If the unit is operating satisfactorily, a torque reading of 35 Nm should be obtained whilst
turning the axle shaft at 20 rpm (e.g. one third of a turn per second).
If a torque reading of less than 25 Nm or more than 80 Nm (@ 20 rpm) is obtained, remove differential case and
inspect the differential components and repair or replace as necessary.
However, if the Hydratrak Coupling cartridge unit is faulty it will require replacement with a new Coupling unit, as it is
a sealed, non-serviceable fluid filled component.
DO NOT ATTEMPT TO REPAIR OR WELD THE
COUPLING UNIT.
Suspension Page C-23
Page C-23
vii. Install brake disc and caliper. Tighten caliper attaching bolts to the correct torque specification.
NOTE
CALIPER ATTACHING BOLT TORQUE
SPECIFICATION IS 55- 70Nm
viii. Install road wheel.
NOTE
When installing the wheel, align the marks made
prior to removal.
ix. Remove safety stand and lower vehicle.
x. Tighten road wheel attaching nuts to the correct torque specification.
NOTE
TORQUE SPECIFICATION IS 100-125Nm
xi. Refit wheel cover/centre cap.

6 Limited Slip Differential
From Holden Commodore VS series Service Manual
When servicing a vehicle fitted with a Limited
Slip Differential (including Hydratrack type),
never run the engine with the transmission in
gear and one wheel raised. The driving force
to the wheel on the ground may cause the
vehicle to move.
NOTE
'On Car' type wheel balancers are not
recommended for use on the rear wheels of cars
equipped with a Limited Slip Differential. One
rear wheel will drive if in contact with the ground
when the opposite wheel is raised. This type of
balancer may be used by removing the wheel
opposite to the one being balanced with the
vehicle raised and supported on safety stands.
(Refit wheel nuts, reversed, to retain brake disc).
