Abstract: This paper analyses the effect of residual stress in the distortion of the axle drive shaft. Residual stress is the stresses that remain in a solid material after the original cause of the stress has been removed. An axle drive shaft of 20MnCr5 material is been analyzed. Research is carried out on two axle drive shaft. In one shaft, after the last manufacturing step was sent through residual stress relief process by shot peening process. And both shafts after going through heat treatment process showed variation in distortion. The shaft with stress relief treatment showed less amount of distortion compared to the other shaft. Therefore a stress relief shot peening process is recommended for reducing the distortion in axle drive shaft.
