frontwheels seems flat?

The best help is to get it test driven , WITH a technician , and demonstrate the symptom , THAT would be the quickest safest way. IF the symptom is , while you are driving down the road , the steering wheel suddenly shifts on you like a big gust of wind hit you , have the ball joints checked. IF that's it , don't put it off , could lead to a wheel/suspension MAJOR failure (as in wreck!)
