AURHTQ003 Diagnose and repair heavy vehicle drive shafts
Assessment tool
Version 1.0 Issue Date: April 2024
This unit describes the performance outcomes required to diagnose and repair faults in heavy vehicle drive shafts. It involves preparing for the task, selecting the correct diagnostic procedure, carrying out the diagnosis and the repair, performing post-repair testing, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. Drive shafts include those in agricultural machinery, heavy commercial vehicles or mobile plant machinery.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

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 heavy vehicle drive shafts that they have worked on, 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
manufacturer drive shaft specifications
heavy vehicle with faults in its drive shaft
diagnostic equipment for heavy vehicle drive shafts
tools, equipment and materials appropriate for repairing and adjusting heavy vehicle drive shafts.
