Performance evidence
- align wheels on all steerable axles of at least three different heavy vehicles.
- In the course of the above, the candidate must measure each of the following steering angles, and make adjustments where required by job specifications: camber, caster, king pin inclination (KPI), toe (toe-in and toe-out), toe-out on turns.
Knowledge evidence
- methods to locate and interpret information required to carry out heavy vehicle wheel alignment, including: manufacturer specifications and procedures
- workplace procedures required to carry out heavy vehicle wheel alignment, including: establishing serviceability of tools and equipment, pre and post wheel alignment procedures, documentation procedures, housekeeping procedures, including: examination of tools and equipment, storage of equipment, identification, tagging and isolation of faulty equipment, disposal of excess materials, recycling procedures
- workplace health and safety (WHS) requirements relating to heavy vehicle wheel alignment operations, including: procedures for raising and supporting heavy vehicles or machinery
- steering geometry and wheel alignment angles, including: Ackermann principle of steering, camber, caster, KPI, toe-in and toe-out, toe-out on turns, steering axis inclination, two wheel and twin four wheel steer
- vehicle pre-alignment inspection procedures, including: analysing tyre wear, inflating tyre, adjusting wheel bearing, inspecting steering and suspension, determining wheel run-out, determining vehicle height, checking chassis and axle alignment
- types and operation of wheel alignment systems, including: laser aligners, visual aligners, camera aligners
- procedures for measuring and adjusting steering angles, including: camber, caster, toe-in and toe-out, toe-out on turns
- post-wheel alignment testing procedures for heavy vehicles.
Foundation skills
- Learning: Locates required sources of information efficiently

Questions about assessing AURHTD104
What does an assessment tool for AURHTD104 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AURHTD104 needs to address all 31 unit components: 4 elements with 16 performance criteria, 2 performance evidence requirements, 8 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.
How does Auditori generate an assessment tool for AURHTD104?
Auditori pulls the current release of AURHTD104 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.
Is the first assessment tool really free?
Yes. Every new account includes one free credit — enough to generate the complete assessment tool for AURHTD104 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing AURHTD104 assessment instead of generating a new one?
Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of AURHTD104, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
