1995 Toyota Corolla Front end noise

Tires and Wheels problem
1995 Toyota Corolla 6 cyl Front Wheel Drive

I have a noise coming from the left front end. The faster I go the louder the noise. The front end also shakes a bit the more I increase speed. I have replaced the struts, brakes, rim and the tire. Nobody seems to be able to tell me what's wrong. When I had the brakes done I was told that I needed to have the calipers replaced. Since I have taken my car to 3 different places & get 3 different answers I did not have the calipers replaced. I am a 46 yr old woman & have spent alot of $ to still have the same problem. Please help me if you can. I feel as if the mechanics are taking advantage of me.
