OVER THE COURSE OF THE LAST YEAR, THE STEERING IN MY BMW Z-4 HAS FELT LIKE I HAVE TO FIGHT TO STAY ON THE ROAD. IT IS JERKING & PULLING THE CAR OFF CENTER MAKING IT VERY DIFFICULT TO DRIVE AND FEEL SAFE. THE STEERING WHEEL ALSO "STICKS" RATHER THAN ROTATING SMOOTHLY WHEN I TURN TO THE LEFT OR RIGHT. THIS CONDITION IS PROGRESSIVELY GETTING WORSE, I WAS DRIVING ON THE INTERSTATE LAST WEEK AT APPROX. 55 MILES/HOUR AND SEVERAL TIMES THE CAR SWERVED HARD PULLING ME INTO THE NEXT LANE OF TRAFFIC COMING VERY CLOSE TO CAUSING AN ACCIDENT. *JS
