my 2012 3,92 LSD spins both tires on left turns when i gas it but only the inside tire on rights, is that normal?

 

U sure you have the LSD?

It´s not supposed to work that way.

 

You can easily test if you have limited slip. Raise the rear so both wheels are off the ground. Spin one of the tires forward, if the other tire rotates the same direction you have a limited slip, if it rotates the opposite direction you don't!

Good luck!
