When the vehicle is moving on a road and when it takes a turn both the surface and inside wheel got to travel different distance so here the differential gearbox comes into role. The transmission utilized in the vehicle contain a component which is employed to transfer power from propeller shaft to both the wheels is named as differential. It’s an assembly of drugs in an epicyclical gear train which enable the rotation of two shaft at two different speed, used at the rear side of the vehicle to rotate the wheel faster than the opposite. This study deals with the differential problems during various situations and solutions to each problem by modifying the content, configuration and using a different method. Any researcher's view in this paper is to increase performance by increasing the power of its weight by adjusting its shape by changing either the chain differential or the gear differential. This differential development increases its performance by cracking as the load works.
