6x6 front locker

Is there any way to tell if a 6x6 front axle has a locker in the diff without stripping it?
It has a round drive flange.

If it has a locker in it it won't differentiate. That is both wheels will turn in the same direction if you turn one of them.

Thanks Brian.
Just locked the input and turned one hub. The other turned the opposite way.
Bummer.
