What is happening when the inter-axle is in the locked position?
The inter-axle differential lock is used on vehicles with tandem rear axles. Use the lock position only when you approach conditions where one or both wheels of an axle may slip. The valve locks the differential and causes it to act as a “through drive,” transmitting power equally to both axles.

How does an inter axle lock work on a differential?
So, the inter axle lock will lock the axle together to each for 50% power to each axle not matter what. Differentials will only lock in the tires on the axle to each get 50% of the power sent to the axle. With them both of them on, you can pretty much get yourself out most situations.
Why does an inter axle lock cause a car to spin?
Just like a differential that will send all the power to the on wheel that is in the air (less traction) instead of the on the ground, the inter axle lock will do the same the thing with the axles. Which why when stuck in mud or on ice, you will see one axle spin.
