Whenever the car is moving I can hear a loud whinning / squeaking noise coming from the front wheels. It does it all the time..when coasting in gear, in neutral, and braking. Then last night I was driving on the highway and all of a sudden I felt a thumping sound coming from the front end. I can feel it in the floor. It almost feels like a flat tire but its not because I can't feel it in the wheel itself. It doesn't do it all the time. It comes and goes. It also doesn't matter if I'm stepping on the gas, brakes, am in gear or not. What could this problem be? Any info would be a great help.
