1 General Information
The power assisted steering system for MY2004 VY All Wheel Drive Wagon carries over from MY2004 VY & V2 Series
vehicles with the following exceptions.
• The steering gear pinion shaft is longer due to the unique new cross member design of the All Wheel Drive
Wagon, catering for the higher ground clearance and front drive train. The lower steering coupling to the
steering gear remains unchanged.
• The steering gear retains the VY steering gear specification, but utilises the roll imprinted Monaro control valve.
This control valve improves steering assist boost for parking speeds to offset the increase in front end weight.
• The location of the steering gear assembly mounting points are lower due to the unique new cross member
design of the All Wheel Drive Wagon, catering for the higher ground clearance and front drive train.
• New power steering oil pipes, hoses and cooler locations catering for the unique new cross member design of
the All Wheel Drive Wagon.
For information not contained within this Section, refer to Section 9, Steering in the MY2004 VY and V2 Series Service
Information.
NOTE
A driver’s inflatable restraint (airbag) is fitted as
standard equipment on all MY2004 VY & V2
Series vehicles. For detailed information
regarding the driver's airbag, including system
enable and disable procedures, refer to
Section 12M, Occupant Protection System in the
MY2004 VY & V2 Series Service Information.

2 Service Operations
ATTENTION
All steering gear 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 number or a GM approved equivalent. Do not use fasteners of an inferior quality or
substitute design.
Torque values must be used as specified during reassembly to ensure proper retention of all steering
components.
Through out this Section, fastener torque wrench specifications may be accompanied with the following
Identification marks:
! Fasteners must be replaced after loosening.
"
""
" Vehicle must be at kerb 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 Power Steering gear
LT Section No. – 06-275
ATTENTION
The following fasteners have either micro encapsulation or incorporate a mechanical thread lock and should
only be used once. If in doubt, replacement is recommended when performing this operation:
#$ Steering gear pinion shaft to intermediate steering shaft coupling attaching nut.
The following fasteners MUST be replaced when performing this operation:
!
!!
! Steering gear to cross member attaching nut.
