Well last night me and my friend decide to go play around in the bronco 2. I put it in reverse and romped on the throttle and it felt like it popped out of gear. Clattered real loud and the spd went up but it did not go anywhere. So i put it in neutral the clattering slowed to a stop then i took off. It happed again shortly after. So i put it in four wheel drive. Worked fine for a while then everything quit. The wheel moves for a second then just stops and makes a real loud clatter and im not that familiar with how four wheel drive works at all. so i have no idea what the problem is

 

Well,you probably broke your rear drive shaft or an axle shaft, plus,if it does not move at all now, you probably blew a hub up front too.
