Kind of differential gear
Gear Def
It is def with a built-in umbrella-type of gear called a bevel gear.
Since the assembly and maintenance is easy, it says that def beginner.
By put a dedicated oil in the differential case, it is possible to adjust the degree of effectiveness of def.
If during cornering floats in-side of the tire, there is a drawback that it becomes not transmitted driving force in the out side of the tire.
Ball Def
Pinching a small ball made of metal with two plates instead of the gear, and absorb the rotational difference in the frictional force.
Assembly and is def for advanced users because of the difficult adjustment method.
Even floating in-side of the tire, since the driving force is transmitted to the out side of the tire, behavior during cornering is stabilized.
One-way diff
It is the part that incorporates a bearing to rotate only in a certain direction.
Not exactly a diff, but in order to front tire left and right becomes a free rotation at the time of the accelerator OFF, to overcome the weaknesses of the bend hard to 4WD vehicles can be said as an essential part.
Since the habit out on the accelerator ON-OFF Then behavior during cornering, you will need a high driving skills.
