4 Suspension Ohlins Supplement
4.1 General Information
The purpose of this supplement is to provide information on the new Ohlins Adjustab le Performance Suspension optional
on VZ Clubsport and GTO Coupe
The Ohlins system consists of oil filled front struts and rear shock absorbers that have adjustable bump and rebound
settings. Adjustment is carried out via knobs fitted to each shock absorber a ssembly. Removal and replacement of the
front strut and rear shock absorber is similar to the Holden suspension systems with the exception of front strut hoses
and canisters which are mounted on the front strut brace in the engine bay. Refer to instruction drawings
04I-050003, 04I-050004 and 04I-050002.
The front mounting is a unique adaptation of the Monroe front strut with a HSV designed a nd developed upper mounting
system.
The rear dampers utilize the standard top and bottom shocker mounts. However as thes e units are fitted with external
gas canisters, the front canisters are supported on the strut brace in the engine bay. The rear can isters are a “piggy
back” unit and are affixed to the shocker.
The adjustment knobs are located on the remote canister units. These knobs can be tur ned by hand clockwise to
increase damping force, or anti-clockwise to decrease dampi ng force.
When movement of the vehicle occurs, fluid flows through the apertures and shims, underneath and above the piston
(depending on whether a compression or a reboun d movement has occurred) .The fluid that has been displaced by the
volume of the rod is forced into the external fluid reservoir. The separatin g piston between the oil and th e gas has been
displaced and gas pressure increases. The result of the increased gas pre ssure against the rod and the oil flow through
the apertures in the shims provide the resistance to movement or damping. Gas is also used to help alleviate cavitation
in the oil.
Suspension Page C-13
Page C-13
4.2 Servicing/Inspection and Maintenance
Clean the shock absorbers external ly with a soft detergent. Lift the dust cover and use compressed air. Be careful that all
dirt and debris is removed. Lift the bump rubb er and clean the area below. Keep the shock absorbers clean and al ways
spray them with lubricant (CRC 5-56, WD 40 or similar).
Inspection Points
1. Check brackets or bushes for possible excessive play.
2. Check the piston shaft for leakage or damage.
3. Check the shock absorber body for external damage.
4. Check the dust cover for damage.
5. Check the spring condition.
6. Check for excessive wear of rubber components and dust covers.
7. Check fastening points to vehicle.

5 Rear Final Drive and Drive
S hafts
5.1 General Information
All HSV models utilize up rated propell er an d drive shafts with a higher torque capacity to match the performance of the
unique LS2 engine.
Propeller and drive shaft diameters have b ee n increased, along with ne w propeller shaft flexible couplings with a larger
PCD for the bolt attachment arrangement.
The differential is a high torque capacity LSD with shot peened ge ar sets and all models have a 3.46:1 ratio to
complement the ratios in the ne w M12 version T56 manual and the M32 (4L65E-HMD) automatic transmission.
The final drive and drive shafts fitted to MY 2005 HSV VZ vehicles, carries over from
MY 2005 Holden VZ vehicles, except for the following items:
With the increased output from the GEN IV V8 (LS2) engine, both the front and rear propeller shaft rubber
couplings have larger d iamete r s. T his has resulted in an increased pitch circle diameter (PCD) change from 96 to
110 mm for the attaching bolts.
With the increased PCD for the propeller shaft rubber couplings, a revised design final drive pin ion flange is now
fitted, that results in two new special tools being release d. These tools are used to:
a Hold the pinion flange when loosening/tightening the pinion flange nut.
b Remove the pinion flange from the final drive pinion when replacin g the flange, the oil seal or when
undertaking a final drive overh aul procedure.
Both new tools have the earlier and later PC D dimension holes included, which allows them to be used on this and
earlier model vehicles. The procedure for fitment and use of these new tools is the same as detailed in the Holden
VZ Service Information, Section 4B Final Drive and Drive S hafts.
Refer to 7 Special Tools in this Section for the new tool details.
To enable the final drive p inion bearing preload to be measured, the fabricated wooden disc requir es some
modification to allow it to be used on th e revised diameter pinion flange. R efer to 7 Special Tools in this Section for
the necessary changes.
Both drive sh afts are now fitted with a plunge type constant velocity joint at the inner a nd outer locations.
This means that the same servicing procedu re for the inner constant velocity joint (plunge type) detailed in the MY
2005 Holden VZ Service Information, Section 4B1 Fina l Drive and Drive Shafts, can now be adopted for any of the
four, drive shaft constant velocity joints fitted to MY 2004 HSV VZ vehicles.
A revised procedure has been developed to select the hypoid pinion p ositioning shim. This has resulted in a
changed dimension spac er to be used, which is incorporated into pinion set gauge kit, tool number DT-47737. In
addition, with the changed dimensions of the inner pinion bearing, a revised tool has been developed to remove the
bearing cup from the final driv e housing. Details of these revised tools and the procedures relating to their use is
provided here, in the sub-section, "Hypoid Pinion Shim Sel ection" and "Pinion Installation".

5.2 Major Service Operations
Final Drive Assembly Unit Repair
Reassemble
Hypoid Pinion Shim Selection
The pinion posit ioning shim is located between pinion rear (inner) bearing cup and carrier housing.
If the ring gear and pinion or the pinion rear bear ing assembly are replaced, pinion depth must be rechecked with pinion
setting gauge, Tool No. DT-47737. This set includes a dummy pinion spac er, T ool No. DT-47696 and dummy arbour
Tool No. AU408.
The gauge and arbour pr ovide a nominal or 'zero' pin ion as a gauging reference.
NOTES
If a new gear set is to be installed, check that
the same matching number (‘A’) appears on
both the pinion and the ring gear, with either
a white or yellow marker.
The pinion installation marking figure is
indicated by ‘B’, again with either a white or
yellow marker.
Figure C – 1
1 Inspect pinion bearing cups/c ones for nicks and burrs. Replace if damage d.
2 Lubricate pinion front and re ar bearings with the recommen ded differential carrier lubricant. Do not use engine or
other oils, as a misleading rotating torque can be obtained.
NOTE
Make sure that both pinion bearings used on the
dummy pinion to determine the pinion positio ning
shim thickness, are those t hat will be used on the
final reassembly.
3 Install the spacer, Tool No. DT-47696, to the dummy pinion, supplied as part of DT-47737, then install the rear
(inner) pinion bearing onto the dumm y pin ion.
4 Install dummy pinion and rear (inner) bearing into the carrier housing. Fit front (outer) bearing to dummy pinion,
then install the dummy pinion thrust collar and nut (included in pinion set gauge kit DT-47737).
5 Tighten nut on end of dummy pinion, using a
commercially availabl e, dial type torque wrench (1),
until the specified rotational torque is obtaine d.

Suspension Page C-19
Page C-19
NOTES
Once the specified preload is reached,
remove the gauge block from the rear of the
dummy pinion (that al lo wed the p ini on be arin g
preload tightening process to be done).
Rotate the pinion approximately 50 turns in
each direction, then re-check the bearing
preload, readjusting as required, to achieve
the specified figure.
Pinion bearing pre-load is very important
because it retains the pinion in its correct
relationship to the ring gear.
Bearings that are installed with insufficient or
no pre-load will, after a comparatively short
period of running, develop end play. This will
cause noisy operation on overrun and could
be responsible for scuffing of the ring gear
and pinion teeth.
Bearings that have too much pre-load, may
become pitted or flaked and result in
premature failure. It is therefore vital that
bearings are pre-loaded to the specified
torque specification.
7 Position arbour Tool No. AU408 (part of pinion height
setting gauge, DT-47737) in c arrier assembly and
install screw adjusters with side bearing cup s . Adjust
screw adjusters to lightly clamp arbour, using Tool No.
205-463.
NOTE
Ensure that arbour is free of any burrs that may
damage bearing cups.
Figure C – 3
Suspension Page C-20
Page C-20
8 Check clearance between arbour (Tool No. AU408)
and head of dummy pinion with a feeler gauge (1).
Record this dimension.
Figure C – 4
9 On the end of the pinion, a drive pinion installation
marking figure (1) is applied with either a white or
yellow marker. A zero marking ('0') indicates that shim
size equal to the dimension measur ed in Step 8 is the
correct size for this carrier/pinion combination.
A positive marking, e.g. +3, means that a thickness
measurement equivalent to this numerical marking
must be subtracted from shim size measured in
Step 8. Refer to the following chart for specific details.
A negative marking, e.g. –3, means that a thickn ess
measurement equivalent to this numerical marking
must be added to the shim size measured in Step 8.
Refer to the following chart for specific details.

NOTES
To avoid possible damage to the pinion gear
teeth when pressing the bearing on, ensure
that the press plates are perfectly flat, free of
burrs and foreign matter prior to installing the
rear bearing.
Locate bearing inner race squarely on the
pinion and press only on inner race surface.
Only lubricate the bearing with the
recommended differential carrier lubricant.
Figure C – 9
6 Place the pinion in the carrier.
7 Lubricate pinion front bearing with the recommended differential carrier lubricant and assemble the collapsible
pinion bearing spacer and front bearing onto pini on, while supporting pinion head.
8 Install pinion flange and the o r iginal pinion flang e
retaining nut.
9 Install Tool No. DT-47735 to the pinion flange.
NOTE
Use either the rear coupling to pinion flange
retaining bolts with a 25 mm spacer (e.g. flat
washers) installed first or use three bolts M12 x
1.5 x 40, with the thread extending to within 12
mm of the head.
10 Using a suitable length of pipe (1) to over the hol ding
tool tang, tighten retaining nut until pinion front beari ng
is squarely engaged on the pinion shaft and not
cocked.
11. Remove the pinion flange retaini ng nut, using a
commercially availabl e, 30 mm deep socket (2) and
socket bar.
Figure C – 10
12 Install extractor, Tool No. DT-47736 to the pinion

14 Lubricate pinio n oil seal lips and the pinion oil seal
bore in the carrier housing with Mobilgrease XHP 222
or equivalent grease.
15 Install oil seal into carrier bore using T ool No. E9055
and a plastic faced hammer (1) until the seal fits flush
to 0.25 mm below carrier housing surface.
Figure C – 12
16 Reinstall pinion flange and fit a NEW retaining nut.
17 Hold pinion flange using Tool No. DT-47735 and a
suitable length of pipe (1).
18 Gradually tighten the retaining nut while rotating pi nion
in both directions to seat bearings.
If the retaining nut is over-tightened and pre-
load exceeded, it will be necessar y to remo ve
the pinion from the carrier and a new
collapsible spacer installed. Under no
circumstances must the retaining nut be
backed off to decrease the pre-load reading. Figure C – 13
19 Check bearing pre-load freq uently by removing flange holding tool (DT- 47735) and installing a pulley and string to
the pinion flange. Refer to 7 Special Tools at the end of this Section for pulley details.

5.3 Pinion Flange
Replace (Vehicles With a Rear Rubber Coupling)
ATTENTION
The following fasteners MU ST be replaced when performin g these operations:
Drive shaft attaching bolts.
Using Old Oil Seal
Resulting from production tolerances in the
length of the pinion flange, it is essential that
the following method be used when installing
a new pinion flange.
1 Raise the vehicle and suppor t in a safe manner. Refer to Section 0A General Information in this Service Information
for the location of recommended lifting and supp ort points.
2 Remove propeller shaft, refer Section 4C1 Propeller Shaft and Universa l Joints , in the MY 2005 VZ Series Service
Information.
3 Remove both drive shafts, refer to Section 4B1 Final Dr ive and Drive Shafts in the MY 2005 VZ Series Service
Information.
4 Check and record pre-load at pini on flange as follows:
a Fit a pulley (1) to pinion flange, using three
suitable bolts and attach a cord around p ulley
and to a spring scale (2).
NOTE
Use either the rear coupling to pinion flange
retaining bolts with a 25 mm spacer (e.g. flat
washers) installed first or use three bolts M12
x 1.5 x 40, with the thread ext ending to within
12 mm of the head.
For details of the fabricated pulley, refer
7 Special Tools at end of this Section.
b Start rotation of pulley and whilst in motion
(approximately 50-60 rpm) note and record
reading of spring balance.
This pre-load reading includes pinion beari ngs,
side bearings, meshing effect of gear set and
pinion oil seal.
To determine pre-load, multipl y readi ng on
spring balance by radius of pulley. Figure C – 14
Suspension Page C-25
Page C-25
Example: With a pulley diameter of 152 mm, the radius is 76 mm, which equals 0.076 m. With a spring balance readi ng
of 25 N, the pre-load equals 0.076 m x 25 N = 1.9 Nm.
5 Remove pulley from pinion flange.
6 Attach Tool No. DT-47735 to the pinion flange, using
three suitable bolts to hold pinion flange.
NOTE
If not done before, drill out holes stamped ‘B’
on Tool No. DT-47735 to 12.5 mm.
Use either the rear coupling to pinion flange
retaining bolts with a 25 mm spacer (e.g. flat
washers) installed first or use three bolts M12
x 1.5 x 40, with the thread ext ending to within
12 mm of the head.
7 Insert a suitable length of pipe (1) over the tang of the
installed tool for leverage, then remove the pinion
flange retaining nut, using a commercia lly available,
30 mm deep socket and socket bar (2).
8 Remove Tool No. DT -47735 from the pinion flange.

Figure C – 15
9 Place drain tray beneath differential carrier.
10 Install extractor, Tool No. DT - 47736 to the p inion
flange using the same three bolts used in step 6.
NOTE
If not done before, drill out holes stamped ‘B’
on Tool No. DT - 47736 to 12.5 mm.
If using the original propeller shaft coupling
bolts, they must have a 25 mm spacer fitted
to each, so the tool is clamped to the pinion
flange. If this is not done, the screw thread
on the extractor Tool No. DT - 47736 will not
be long enough to fully remove the pinion
flange.
11 While holding the extractor tool with a suitable
spanner, withdraw pinion flange by tightening the
forcing screw in the direction shown.
DT - 47736
Figure C – 16
12 Ensure that pinion shaft thread is free from burrs, oil, dirt or grease, then coat splines and seal surface of a new
pinion flange with the recommend ed rear axle lubricant.
13 Install the new pinion flange a nd a new retaining nut.
The pinion flange is an interference fit on
pinion shaft splines and should only be pulled
into place by tightening the retaining nut. Do

14 Tighten flange retaining nut gradually until pinion shaft end play is reduced to approximately 0.50 mm.
Should the retaining nut be over-tightened
and the pre-load exceeded, it will be
necessary to remove the differential carrier
assembly and install a new collapsible
spacer. Under no circumstances must the
retaining nut be backed off to decrease the
pre-load setting.
15 Attach pulley to the new pinion flange and using a spring balance, check pre-load. Conti nue tightening nut while
alternatively turning pin io n to seat bearings, until the pre-load figure recorded previously (Step 4b) is reached.
Further increase this original pre-load reading by 0.5 Nm.
NOTE
Rotate pinion an extra 30 – 4 0 turns a nd r e-c heck
the preload to ensure that no change has
occurred.
16 Reinstall drive shafts, refer to Section 4B1 F inal Drive and Drive Shafts in the MY 2005 VZ Series Service
Information.
17 Reinstall propeller shaft, refer to Section 4C1 Propeller Shaft and Univ ersal Joints, in the MY 2005 VZ Series

Front Suspension Service Alignment Data
The tyre life of high performance low profile tyres fitted to HSV VZ vehicles is very
Sensitive to the toe-in setting of the front suspens ion. It is crucial therefore, that care is
Taken to set the toe-in accurately to the correct specification.

The specifications listed are the nominal value with accept able variance from this central poi nt. Where possible an
attempt should always be made to achieve the nominal settings when adjusting.
Front wheel camber alters as a function of front suspension height.
Camber adjusting bolt. After loosening both lower strut to steering knuckle bolts and nuts, adjust camber by turning bolt
clockwise to decrease negative camber a nd anti clockwise to increase neg ative camber. After adjustment, both lower
strut to steering knuckle bolts and nuts MUST be replaced with new parts and tightened to the recommended torque
setting.
The rear wheel alignment should be checked and corrected if necessary (refer to Section 4A, Rear Suspension, in the
MY 2004 VZ Service Information) before checking front wheel Alignment.
