I was just out bashing my savage and i started pulling some crazy donuts, then i realized it was because i was getting no power to my front wheels, then no power to any wheels. I looked inside the diffs, all of the gears have all of there teeth, all of the conecting rods between the diffs and the wheel are intact, when i spin the wheels and then put on the brakes, the diffs stop turning but the wheels dont, I'm not really sure whats wrong i need some help.
