There are three types of rear ends (that I know of)...

The single track or open end - where one wheel and one wheel only, turns. How lame is that.

The common slip or limited slip style diff that puts power to both wheels, but allows for that power to vary from side to side most commonly used in turning. It eliminates one of the tires from chirping or hopping in a turn.

Then there is what I call the True Positive Traction Diff. Not to be confused with the "posi-track" used by (GM) or "trac-lok” use by (Ford). This diff does not belong on the street. It is for race cars . It has no side to side slip. The gears are set, no clutches. And if the input turns "x" times both wheels turn "y" times.
