No somehow the auto hub or the 4x4 engaged on its own.not sure why or what happened but it was violent.Just got back from recovering it from 90 miles from my house.Lucky for me my friend offered to help with this truck and trailer and we towed it home.I noticed today it wasnt as locked up in the front end as bad as it was but if you engage 4x4 it wont move and when you put it in park it makes a ratcheting sound,so i know something is pretty messed up.havent got to really tearing into it yet but Im going to tomarrow I think.I hopefuf it can be repaired,just have to locate parts.
