MOT tester here , the bushes . Jack up car & place on stands . Take a pry bar about 300mm ( 12" for the old school mob ) and see if you can make the bush move in such a way as it knocks / clunks / bangs .
DO NOT swing away at them like an agitated gorilla as that is not how we test them !
If when we test there is some movement without any odd noises or any more movement than the rubber flexing , it is pass or pass& advise
5.3.4 Suspension joints, pins and bushes
Some rubber/synthetic bushes are designed to provide a comparatively high degree of compliance and are therefore likely to show some movement.
You should only reject rubber or synthetic bushes when you can see serious deterioration of the bonding or flexible material.
Many MacPherson strut top bushes are designed to have significant lateral play when the suspension is hanging free. You should only reject MacPherson strut top bushes when play is due to wear or maladjustment.
You should assess wear or play in spring pins and bushes using either:
a small pinch bar
wheel play detectors
Wear is excessive if play is more than:
2mm for a 12mm diameter pin
3mm for a 25mm diameter pin
10% of the pin diameter for pins over 25mm diameter
To fully assess the condition of front suspension components you should use wheel play detectors.
And the above is hot from the test manual !
