Abstract

A method and apparatus for testing a shock absorber and/or suspension system of a motor vehicle uses means (6A, 6B) to raise a wheel (15) and vehicle bodywork (16) to a predetermined height for free dropping so as to cause relative vertical motion between the wheel (15) and the bodywork (16), electronic sensing means (2), such as a laser scanner, to sense a characteristic of the wheel/bodywork relative motion e.g. the speed differential, indicating means (1) for noting the sensed characteristic, and comparison means (3) for example in the form of computer apparatus, for comparing the sensed characteristic with a corresponding characteristic obtained for the vehicle when it has new or as new shock absorbers and suspension system whereby the condition of the shock absorber and suspension system can be checked.
