Abstract. Traditionally, the durability performance of vehicle components and subsystem has been investigated and verified by testing physical prototypes. In this study, we performed durability analysis of the knuckle arm. Knuckle arm is a part that connects the wheel of a car to the rest of the vehicle suspension such as strut, tie rod and control arm. It is loaded by longitudinal, lateral and vertical forces. These forces are typical for handling course, in which high lateral loads occur. Such loads must be taken into account in developing process, because it affects the safety of the car. In this study, the stiffness and durability of the knuckle installed in a small size car are investigated using commercial software. Parametric analytical studies have been carried out to estimate the stiffness and fatigue life using commercial software
