On my 98, I'm getting a vibration that's almost like tire vibes/noise from offroad tires. I'm not running offroad ties anymore (bought a jeep for that) and have Bridgestone Dueller ATs. The problem has started small, was almost not noticeable but is getting considerable louder. I rotated the tires (they only have 5K on them) with no difference. If you're going down the road at 30+ mph and turn to the left like on an interstate on ramp or changing lanes fast, the noise disappears. Turning right doesn'thing. The wheels aren't getting hot (thought of bearing at first.) It drives straight down the road and doesn't pull left or right. You can hear the roar and feel the vibe in the steering wheel. Any ideas?
