Application
This unit describes the performance outcomes required to advise customers on the compliance of steering and suspension modifications with Australian Design Rules (ADRs) for normal road usage. It involves clarifying modifications, determining modification compliance with ADRs, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The steering and suspension systems are those of four-wheel drive (4WD) vehicles, light vehicles and light commercial vehicles.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
Elements Elements describe the essential outcomes. | Performance Criteria Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold and italicised text is used, further information is detailed in the range of conditions section. |
1. Clarify details of steering and suspension modification | 1.1 Confirmation is sought, through discussion with the customer, of the nature of steering and suspension modification 1.2 Modification specifications and dimensions are determined and documented 1.3 Non-standard steering and suspension components are identified |
2. Determine specific ADR information relating to modification | 2.1 ADR bulletin applicable to modification is sourced and ruling on the legality of intended modification is identified and interpreted 2.2 Compliance of modification specifications with ADR requirements is identified and documented 2.3 Interpretation of ruling in relation to intended modification is clarified and discussed with customer |
3. Recommend a plan of action to achieve ADR requirements | 3.1 Suitable plan of action to meet ADR requirements is discussed and clarified with customer 3.2 Workplace documentation, including recommendations for modification, is processed according to workplace procedures |
Evidence of Performance
Before competency can be determined, individuals must demonstrate they can perform the following according to the standards defined in this unit’s elements, performance criteria and foundation skills:
determine the compliance of two of the following vehicle steering and suspension modifications:
lowered or raised normal ride heights
increased track width
variations between front and rear ride heights
replacement wheel and tyre assemblies
replacement steering wheel
fitted or replacement sway bar, track rod or strut brace
conversion of vehicle from left-hand drive to right-hand drive.
Evidence of Knowledge
Individuals must be able to demonstrate knowledge of:
common types of vehicle steering and suspension modifications, including:
lowering or raising vehicle ride heights, including setting different front and rear ride heights
increasing vehicle track width
replacing wheel and tyre assemblies
replacing steering wheels
fitting or replacing sway bar, track rod or strut braces
converting vehicle from left-hand drive to right-hand drive
Australian Design Rules (ADRs), including:
methods for locating
purpose and format
contents relevant to vehicle steering and suspension system modifications
procedures for determining compliance of vehicle steering and suspension system modifications with ADR requirements
procedures for making recommendations to resolve non-compliant modifications.
Assessment Conditions
Assessors must satisfy NVR/AQTF assessor requirements.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of tasks.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the steering and suspension modifications that they have assessed, e.g. repair orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
automotive repair workplace or simulated workplace
workplace instructions
vehicle manufacturer steering and suspension system specifications
vehicle ADRs relevant to steering and suspension system modifications
vehicles requiring the steering and suspension system modifications specified in the performance evidence
tools and equipment appropriate for determining the compliance of steering and suspension modifications.
Foundation Skills
This section describes those language, literacy, numeracy and employment skills that are essential to performance and are not explicit in the performance criteria.
Skills | Description |
Learning skills to: | locate appropriate sources of ADR information efficiently. |
Reading skills to: | interpret information from ADR bulletins containing specialised vocabulary and apply information to intended modification interpret information from manufacturer and workshop literature when seeking steering and suspension system specifications. |
Writing skills to: | legibly and accurately fill out workplace documentation when reporting compliance of steering and suspension modifications. |
Numeracy skills to: | understand and communicate steering and suspension system numerical information in degrees, and in metric and imperial distances measure steering and suspension system components and use basic mathematical operations, including addition and subtraction, to calculate distances, tolerances and deviations from manufacturer specifications. |
