What this usually means
GLA front knocks are usually control arm bushings, drop links or top mounts before shock absorber failure. Ask for lifted inspection proof of play or leakage before replacing full struts.
What to ask the workshop before approving repair
- • Show the diagnostic fault codes.
- • Show photo/video proof of the failed part.
- • Give an itemised quote for parts and labour.
- • Explain why cheaper common fixes were ruled out.
This is not a final diagnosis. It is a money-saving checklist before you go workshop.
