Ok so I hit a pretty big rock one night and it did something to my car. I think it might be the axle but I am not sure. The sound that I have been hearing since then is a popping or clicking sound. It happens when I am at a stand still reving to take off. When the wheels get the force from the engine is when I hear it. It is like the teeth on the axle and the teeth on the engine (or hub) have to find each other before they start working together. Does this sound familiar to anyone, and did I explain it good enough. The car drives fine and I only hear it at take off, and every once and a while when I am making a sharp turn.
