Hi all, anybody knows what happen or how to make the wheel works again. Will appreciate your input. Thanks

 

Hi, thank you for your response and I believe your experty in fixing it. Here was what happened again b4 your response when I tried to back up on snow. I could backed up when slowly, and the wheel turns, tried to dig further by braking hard and accelerate to get kick back up; after this the wheel isn't turn at all. So does it mean the wheel work on friction to propell?... The brake is locking it up! Is this symptom direct to what you said?Many thanks and I'm going drive it today and go from there.
