Help!!!!

When i left your house I had thought that i took it out of four wheel drive and I did but think the motor in the servo went bad and it did not fully disengage. When I was out driving it started to wine in the front really loud and then slowed down fast like it was locked up. The four wheeler shut off but got it to fire back up and it says that it is in neutral but was in gear and would go forward. The faster I go the louder the noise (whine) got in the front. It will not go in reverse and stays in gear no matter what gear I shift it to. What do you think? I am ordering a motor for the servo right now for it to go in and out of four wheel drive to replace that. Not sure where or what the sound is coming from. Please help.
