More than likely means that the ‘Wishbone’ (aka Lower Suspension Arm) Bushes have broken from their sleeves.
His actual failure selection is not correct.
A Bonded Suspension Unit is the rubber cone suspension – not to be found on Fiestas!
The tester needs educating.
The failure for Wishbone bushes is:
2.4.G.3.a
Deterioration of a rubber bush resulting in excessive movement.
Deterioration of the bonding of a rubber bush/mounting resulting in excessive movement.
Note: Some rubber/synthetic bushes are designed to provide a comparatively high degree of compliance. They are therefore likely to show some movement.
Such components should normally only be rejected when serious deterioration of the bonding or flexible material is evident.
