Tests of shock absorber efficiency now form part of the mot test. Checks carried out by members of the European shock absorber manufacturers association (Eu SAMA) show that about one third of the cars of testable age have one or more faulty shock absorber in a dangerous condition. The biggest cause of deterioration is the breaking down of the oil seal through ingress of dirt or grit allowing the fluid to escape. It is estimated that shock absorber life can be 30000 miles on rough roads and about 50000 miles on normal roads. Quite often they form part of the vehicle steering. Illustrations are given of how to detect faulty units and their possible effects on vehicle handling and braking. Examples are also given of how worn shock absorbers can affect other components. It is claimed that an investigation of shock absorber condition after an accident could give a more definite indication of the cause, particularly where no other reasons are apparent. A suggested check list is given that could be used by police in roadside safety checks. /TRRL/
