MOT Test of suspension – description

Suspension – under bonnet checks:

upper suspension joints

  • any other suspension components which can be inspected from beneath the bonnet

Under vehicle checks:

Applies to the front and rear suspension

  • no split pins or nuts missing, no components broken or excessively damaged
  • road springs are checked for condition
  • all suspension joints are checked for condition
  • shock absorbers (dampers) must not leak and must be secure (the vehicle will be ‘bounced’ by the Tester to check that they damp the springs adequately).

The suspension is checked for wear by the assistant applying loads in various ways with the wheels jacked up whilst the Tester observes the result from beneath the vehicle. This may include the use of approved wheel play detectors in some Test Stations.

Note: There are numerous different suspension systems, and the specific nature of any examination will depend to a large extent on the design of the suspension system.
