The rear axle housing is one of the key components in heavyweight carrying vehicles. The failure of this component before warranty period during normal working conditions is not acceptable. There is a big difference in practical road condition and boundary condition made in analytical approach. In the present work, Ansys stress life approach is used for better reliable results. Ratio loading type in Ansys fatigue tool helps to analyze the fatigue failure very close to practical load condition. The fatigue failure analysis is carried out considering static structural analysis methods using mechanical APDL solver. The fatigue life is determined as well as location of critical cross-section, maximum equivalent stress before failure initiation. Further, design enhancement solution to increase the minimum fatigue life is proposed. The stress concentration zone near the spindle is reduced by extrude cut technique using Creo parameter 2.0 solid modeling software.
