With the AC or heat on the dash vent setting dose it switch to blowing out the defrost vent on the dash under hard acceleration? If so it would indicate a vacuum leak which in turn would let the vacuum applied 4x4 hubs disengage.

If the valve is letting a small amount of vacuum to the hub it could cause it to not fully engage and pop out under load?
