I don't suspect the curb hit caused this issue here.This sounds like a fault internally in the gear box or transfer box causing this fault.This can be worn or damaged bearings needing to be replaced or a gear that is failing to need to be replaced.You will need to have this inspected further to locate which component is at fault causing this issue needing replaced.
