While vehicle on moving position, torque is converted from the rear wheel through the propeller shaft. The propeller shaft, which is transmit full engine power from the gear box to the differential and propeller shaft one end connected to the gear box, while the other is connected to the differential in the rear axle assembly. As per study it was found that while vehicle is moving on the curve road or angle in turning moment on the road surfaces , without propeller shaft may caused accident , if vehicle rear wheel drive. Because the distance between gear box and differential changes when the vehicle encounters an uneven surface. Axles act as axis for the wheels to spin around and it is consists by Live Axles and Dead Axle. For the example, live axle which contain differential and through rotary motion is transmitted to the wheels. Dead axle, which do not contain differential and these are simply beams which support the vehicle weight and serve as axis for the wheels. A coiled piece of round or square steel wire which, when compressed exerts, a force that may be used to do some work. Leaf springs or carriage springs are used in the vehicles to cushion the shocks imparted to the wheels by road obstacles.
