4x4 has been working fine until a couple of weeks ago, I remember backing up one very cold morning after the truck was sitting through the night, and it seemed like the truck brakes were holding, I gave it a little more gas and heard and felt what sounded like a snap from the front end, it wasn't too loud but it was noticable, since then I have been having strange issues in 4x4, now the 4x4 is not engaging, the 4x4 light on the dash is solid and I can hear some activity under the truck when it is pressed, I am manually pulling the front axle cable since my actuator is bad too, any ideas would be appreciated.
