I just bought a nitro Evader and while breaking it in, I bumped the front left tire (driving slowly). After that it would not turn. The servo makes noise when wheels aren't turned. I can still sometimes turn left, but not right. If I manually turn the tires to right or left and then turn on the car, I can turn that direction until I center it again. If I turn the wheels when the car is on, it makes a grinding noise (especially when turning right). Can someone help with out with this?
