Transfer Case Question

[redbird]

Vehicle locked up at highway speed, slid front tires down to about 15 mph
at that point tires unlocked. It was probably brakes applied via the Stabiltrak
however I am trying to check everything.

One more thing. If I block front tires against something solid and force the rear to spin, I hear a clicking noise from lower part of dash around the steering column and the traction light flashes. The same sound occured when I had the brakes lockup and slide. Any help is appreciated
