Manufacturing of differential housing includes many process namely shot blast, welding, swaging, facing, cooling etc. where after each process the change in dimensions of the component is seen and hence gives rise to change in axis of axle and runout is generated. The main aim of study is to identify the change in runout after every process and identify the maximum runout creating process. Cold swaging process has major effect on runout when done before welding cover on the housing. Therefore the effect of cold swage process before and after welding cover is being discussed in the paper. Housing part number R145.7 QC667 is being studied over this study.
