Reinstall differential into car and fill with oil. Final Drive and Differential System Technology The differential is a set of gears that divides the torque evenly between the two drive wheels and it allows one wheel to turn faster than the other. The tractor rear wheels are not directly attached to the half shafts but the drive is taken through a pair of spur gears. 60 ° C. Move vehicle onto a lifting platform or over a work pit so that it is absolutely level. The Propeller Shaft The final drive unit has three functions to perform: it gears down the speed of the propeller shaft to a suitable road wheel speed, it divides the transmitted torque from the engine between the two driving wheels and, except in the case of a transverse engine, it turns the drive through a right angle, transferring it from the propeller shaft to the driving wheels. This allows wheels to run at different speeds in a turn with least resistance. �-���+�+xGQ��������}_�ӓ^�'V)���4w�ׄ�0�C�����GGӣJs�*��S:�t�>j�Xڕ�9���y/�4�RU?�4�e��cM���^�1��F�0�pUSs�30ѕ��4��>Z�������_�e=GO+&r�����Q�>��%,���|J�ds��J=�*������� ����Q6��+�6�I���X��`�r��� Thus, because the two wheels are not driven with the same speed, a differential is necessary. It acts as a Final gear reduction typically 4:1, and is must be able to distribute drive to both driving wheels and allow both those wheels to travel at different speeds when cornering..
