How can I verify if the diff I have, is an open diff or a LSD diff?
I can turn about 3,5 times for 1 full circle of a flang. So it's a 3,45 or 3,64
Both flanges turn the same way (there's nothing mounted on the flanges) where they're free of torque.
Is there any sign or marking that's says what ratio the diff is?
there a number on the housing, and a number on the bolted backplate.
Also a mark of 280 or 290 on top op the housing, and HH1 or something like that.

With diff of the car the flanges tend to rotate the same way so it not a good test, if you can take the cover plate of you can tell just by looking inside

Unless the LSD is really worn out, then it’s possible with a little effort but then also you can feel the resistance.
