The aim of this project is to reduce the weight of the steering knuckle without compromising the strength of the steering knuckle. This Steering Knuckle is one of the critical components of a vehicle that links suspension, steering system, wheel hub, and brake to the chassis. It undergoes different loading under different conditions. There has been a strong trend towards the adoption of optimum materials and components in the automotive industry. The reason for this research paper is to design a knuckle that has low weight so that vehicle unspring mass can be reduced. In this project, the integrated steering knuckle is used. This research program aimed to optimize the best use of material for the steering knuckle and compare the analysis of steering knuckles made from three materials i.e. Gray cast iron, aluminum which is recently using and Mild steel is the suggested material.
