When
a vehicle is negotiating a corner, the outside wheel has to travel
a greater distance than the inside wheel. Therefore the outside
wheel must turn faster than the inside wheel. The differential is
the device within an axle assembly that differentiates the wheel
speed between the two wheels. The differential also transmits the
power from the ring gear to the axle shafts and determines how much
power is delivered to each axle shaft. |

| The conventional differential transmits power through a set of spider and side gears to the axle shafts. Power is normally equal to both shafts. But, if one wheel slips, the other wheel receives very little power. This differential is fitted as standard equipment on most vehicles due to its suitabilty for everyday driving on paved roads. | |||||

| While similar to conventional differentials, limited slip type differentials add a friction medium to the assembly to maintain equal power to both axles even if one tire begins to slip. When load is applied to the differential, the friction plates are also loaded, causing a good positive power flow to both tires. | |||||

| This type of differential transmits power through a set of automatic locking dog clutches. This automatic locking action keeps both axles locked together except while cornering when they unlock to allow normal differentation. Severe off-roading demands this type of differential. | |||||
 |
|||||
| Manual locking differentials offer the driver the option of choosing between a conventional or a fully locked differential at the touch of a button (cable, etc.). This provides versatility in a vehicle that will be used in both street and extreme off road situations. | |||||
