2 way diff and ratio's answered

[stevek]

Ok both wheels spin the same way, but I was told that all this indicates is that I have some sort of an lsd, but does not indicate a 1.5 way or 2 way?
I would like to know is there any other way of telling what diff it is without taking it out and opening it up

my s15 when jacked up one wheel goes one way the other the opposite direction and thats got a helical diff.... they lock using torque rather than clutch plates...id say you have a proper locker in it imo anyway
