Center Differential


A Center Differential also called the interaxle differential, is a two-position differential located in the driveline or transfer case of some four-wheel-drive vehicles. Its function is to compensate for any difference in front and rear-wheel travel, which allows the front and rear axles to operate at their speeds without forcing wheel slippage during normal driving on dry roDifferential also called the interaxle differential, is a two-position differential located in the driveline or transfer case of some four-wheel-drive vehicles. Its function is to compensate for any difference in front and rear-wheel travel, which allows the front and rear axles to operate at their speeds without forcing wheel slippage during normal driving on dry road surfaces.

  • When total traction is lost at any one wheel, all the torque will be delivered to that wheel, and the vehicle will be immobilized until the driver locks up the transfer case differential through a lever inside the vehicle.
  • On the other hand, traction must be lost at both the front and rear wheel if a limited-slip differential is used in the transfer case to stop differential is used in the transfer case to stop the vehicle.
