CENTER DIFFERENTIAL
Manual Transmission and Differential
2. DURING TURNS AT LOW SPEEDS
During turns at low speeds, rotating speed difference occurs between the front and rear wheels,
as well as between the left and right wheels. More particularly, the front wheels rotate faster than
the rear wheels. The center differential then acts to absorb the speed difference to enable smooth
driving.
Although the speed difference is small under this condition, operation of the viscous coupling
causes more torque to be transmitted to the rear than to the front.
