Group B Anti-roll Bars, Joints and Subframes
Inspect anti-roll systems, pins, bushes, arms, ball joints, dust covers, brackets, mountings, subframes and prescribed areas.
How to prepare for this year's assessment
Start with group and vehicle class, confirm whether a rule applies, follow the prescribed inspection or administration method, and classify only the evidence permitted by the live source.
Core concepts
Concept 1
Inspect anti-roll systems, pins, bushes, arms, ball joints, dust covers, brackets, mountings, subframes and prescribed areas.
Exam cue: Identify whether the scenario belongs to Group A or Group B before selecting a manual.
Concept 2
Trace the component, joint and attachment path and distinguish wear, deterioration, insecurity and structural impact.
Exam cue: Trace the component, joint and attachment path and distinguish wear, deterioration, insecurity and structural impact.
Concept 3
The current syllabus specifically lists anti-roll bars, ball joints, dust covers, pins, bushes, attachment brackets, mountings and subframes.
Exam cue: Use the source version and effective date that apply during the live 2026–27 training year.
Concept 4
A damaged dust cover and a worn or insecure joint are separate findings with different manual outcomes.
Risk pitfalls and guardrails
Failing the associated joint without evidence or missing damage at the supporting mounting area.
Guardrail: Do not replace current manual wording with workshop preference, memory from an earlier year or an assumption based on appearance.
Treating workshop repair preference as the statutory MOT test outcome.
Guardrail: Do not replace current manual wording with workshop preference, memory from an earlier year or an assumption based on appearance.
Reproducing a sample answer without checking current application and evidence.
Guardrail: Use public examples to identify concepts only; the live source and current facts control the result.
Memory anchors
Component, Joint, Mount
Inspect the full load path rather than one visible part.
Cover Versus Joint
Classify dust-cover condition separately from joint wear.
Subframe Includes Support
Check attachments and prescribed mounting areas as required.
Group B Anti-roll Bars, Joints and Subframes: Source
Confirm the answer in the live DVSA guide, inspection manual or applicable special notice.
Group B Anti-roll Bars, Joints and Subframes: Sequence
Identify group and class, confirm application, use the prescribed method, then classify the evidence.
Group B Anti-roll Bars, Joints and Subframes: Annual Boundary
Keep the 2026–27 assessed topic allocation separate from live rule changes and earlier training years.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
