This paper covers the combination of analytical and experimental method to predict the strength and fatigue life of automobile suspension components. It is described by four steps. First, dynamic loads acting on the vehicle are determined and stored in data bank. This load history is measured by Wheel Force Transducer at the wheel center during travel on the HMC proving ground. Secondary, it is applied to finite element system model and stresses in each component are estimated. Most of maximum stress acting in the suspension component is less than that of material yield strength. Third, stress history is applied to predict fatigue life of each component by using 'FALIP'. Finally, to examine predicted strenght and life, accelerated rig test on components and vehicle test on the proving ground are executed.
