odd vibration/suspension issue

[Brammer]

- So I'm at a loss on what could be wrong here. 2002 gp gt with 109,xxx on the clock. When going above 55 mph driving in a straight line there is a humming/howling noise coming from the rear end and the ride has gone from soft to a vibration, but not enough to vibrate the mirrors.

- When turning right it gets a little worse, but if accelerating and turning right like an entrance ramp(30-45mph) it gets really bad. This causes the mirrors to shake and the steering wheel to vibrate it almost feels like the wheels are wobbling during this.

- If I turn the wheel to the left approx 10 degrees or more the humming/howling disappears and the slight vibration stops. Accelerating left causes no issues.

- To add to the complexity when going straight with even slight throttle(+55 mph) if the car dips down due to a bump in the road that slight vibration feels like the rumble strips on the highway until the suspension rebounds.

Any help or insight would be greatly appreciated....

sounds like a real bad wheel bearing.

I had just changed the wheel hub assemblies on front left and right. I thought the same thing so I took em off returned them under warranty and got new ones.....same thing still.....

you said the noise is in the rear.

that means its a rear wheel bearing.
