My 1999 Lexus has a light but definite vibration that lightly shage the whole car at various speeds (30 -80 MPH) It seems to get worse when level speed is reached OR while navigating a curved road. I had the tires balanced and an alignment ==\> no effect. I read some research re: bushings in the upper and lower arms ?? The labor may be expensive and so I wanted to get it from the experts. Thanks in advance for any help. P.S. I enjoy your show.
