How A Differential Works

Sunday, September 4th, 2011

When a car turns a corner, one wheel is on the “inside” of the turn, and the other wheel is on the “outside.” Consequently, the outside wheel has to turn faster than the inside one in order to cover the greater distance in the same amount of time. Because the two wheels are not driven with the same speed, a differential is necessary. A car differential is placed halfway between the driving wheels, on either the front, rear, or both axes (depending on whether it’s a front-wheel drive, rear-wheel drive, or 4-wheel-drive vehicle).
