Objective to checked bearing to bearing distance in four wheeler gear housing and distance of hypoid pinion gear shaft. To reduce or minimize the gearing housing assembly end play, for that we have to calculate and put standard shim at the end of shaft while assembly. For that requirement of customer to give customized gauging system which gives precise measurement, Effort less, easy process, Time saving and productivity improvement. Therefore the work on design and customized gauging system for shim selection method through design calculation and finite element analysis. The system will fully reliable and strong with the help of Finite element analysis of multi- gauging system for future aspect. As study of system Locator and Sliding plate have more load and forces while gauging condition. For that we study the design and complete FEA analysis. Also to ensure the reliability of the gear housing measurement system, the researcher was required to verify the precision and accuracy of the measurement system by repeatability trials. In the gear housing bearing to bearing distance measurement and inspection procedure, operator and the indirect gauging mechanism are the two key elements.
