A guy sold me a gearbox and told me There was a Mfactory LSD inside.
How can I recognize it?
Wen I turn one wheel, the other turn on other direction, is it normal?

 

Open the tranny, tear out the diff, look for MFactory markings on it.

 

The older LSD's aren't etched. You can tell by looking at the bottom of the LSD (split the case and it is the side that you can see with the diff still in the housing. Post a pic and I'll tell you if its an MFactory or not.

 

The problem is that tranny is into the car!
Is it normal that wheels turn in different Rotation?

 

Pull an axle out and take a good, clear, well lit pic of the diff. I won't be able to tell you if its an MFactory, but I can tell you whether its an OEM helical, OEM open, Wavetrac, OBX, or something else.

 

Ok thks

 

About lsd can you confirm me If When you turn a wheel, the other one turn in opposite?
