Why do you need a differential?
In automobiles and other wheeled vehicles, the differential allows the outer drive wheel to rotate faster than the inner drive wheel during a turn. This is necessary when the vehicle turns, making the wheel that is traveling around the outside of the turning curve roll farther and faster than the other.
How much does a differential cost?
The cost to replace a rear differential ranges from $200 to $400. However, if repairs included changing the gears, the price can jump significantly up to $1500 to $4500. Your vehicle’s rear differential is responsible for controlling the rotation of your wheels.
What is a bad differential?
Differential or transmission are whining. One of the symptoms that is most commonly associated with bad or failing differential or gear oil is a noisy transmission or differential. If the gear oil runs low, or becomes excessively dirty, it can cause the gears to whine or howl as they turn.
What is the function of differential in a vehicle?
To transmit the engine power to the wheels
What does the center diff do?
The center differential consists of a set of bevel gears and a viscous coupling. The center differential has the following two functions: distributing the engine torque to the front and rear wheel drive shafts and absorbing the difference in rotating speed between the front and rear wheels. The engine torque enters the center differential case from the transmission s driven shaft.
What exactly is a differential?
In mathematics, differential refers to infinitesimal differences or to the derivatives of functions. The term is used in various branches of mathematics such as calculus, differential geometry, algebraic geometry and algebraic topology .
