Rear axles

Rear axles are important component of an automobile unit.  Cars of front engine rear wheel type uses rear axles for transmitting power from differential to the driving wheels. Rear axles also serve two more functions. One is acting as a bearing rod for road wheels and the other providing attachments for the springs.  Broadly there are two types of axles. They are dead axle and live axle. Bullock cart employs dead axle which itself does not rotate, but wheels on this axle rotate. Automobiles use live axles which rotates itself.  The three types of rear axles are half floating rear axles, three-quarter floating rear axles and fully floating rear axles.  Lubrication of rear axles is necessary for the proper functioning and lubricating oil is always poured in the axle casing.  Leakage or overflow of the oil in the axle casing will lead to brake slipping.
