Driving straight and when turning to the left. Worse when turning left. No noise at all when turning right. The roaring noise sounds like the left wheel bearing needs to be replaced. The metal to metal sound does not sound like the wheel bearings. The CV boots look good. No clicking sound when turning. Car also vibrates when turning left. When driving straight at at 5 to 10 miles an hour, turning the steering wheel left to right, when I steer to the left just slightly I here a whining noise. Power steering fluid level is good. Anybody got any idea's. Got the car back. Wheel bearing and rotor replaced. Sounded and handled just like it did when I brought it in. Took it back today. Same mechanic found the problem in about 5 minutes. The tranny has 4 mounting bolts, 3 were missing and the last one left was half way out. He said he had to retap the bolt holes. He said that it looked like the tranny had been replaced because it had new seals, gaskets,etc. I asked the mechanic if the tranny would be a problem down the road because of the bolts missing ans he said no. NOW it runs and sounds like it should.
