Steering Wheel Vibrate problems of the 1998 Toyota Camry

I bought my car new in may 1998. I had the brakes replaced at least 3 times the first time being 11/8/99. I have complained several times of front end noise, car drifting, and steering vibrations. Each time I was told it was either incorrect tire pressure, out of balance or alignment. Most of the time I was told the noise is normal road noise and the drifting is normal drifting. I think something needs to be done about this. My car is no longer under warranty. I bought a new car to avoid having to pay for all these expensive repairs and because I had a 7 month old baby. I now have two children and sometimes I am afraid to drive them in my car. My car still makes the noise, drifts, steering wheel vibrations. I have even reported clunking noises from the bottom of the car and was told it needed to be greased or the bolts tightened. It seems Toyota has known about this problem all along and decided to do nothing about it. Toyota should be forced to fix all the vehicles with this condition. It shouldn't take someone's death before something is done. I am a first Toyota buyer and very disappointed. I can not afford to fix a suspension system that was defective at the time of purchase, nor should I have to for a $20,000 car that is barely 5 years old with only 53,000 miles on it. I thought the mechanics were right about normal noise until I saw all the complaints about the suspension system. Please help. Thank you. Jb.
