2000 Ford Focus front end noise


My Focus has about 118,000 miles. Over the last 3-4 thousand mile it has started becoming more noiseier(?) in the car. If I am in a slight right hand turn on the highway, the noise seems to go away. Straight, and it is a little noisy in the car. A left turn, and we can’t even hear each other talk. It’s like running over the ridges on the shoulder of the highway, without the viberation. I jacked up the car on each side to check the wheel bearings, and the tires had no movement at all when I tried to move it at the 6 and 12 o’clock position. Any help on this would be greatly appreciated. Terry
