AS THE SPEED GOES UP AND DOWN THERE IS A CONSISTENT HOLLOW THUMPING NOISE. THIS HAS BEEN GOING ON FOR OVER A YEAR. HAD IN DEALER TWICE AND THEY REPLACED LEFT FRONT WHEEL BEARING AND INTERMEDIATE SHAFT BEARING. NOISE IS STILL THERE. TOOK CAR TO FIRESTONE AND MECHANIC DROVE AND HEARD NOISE AND SPEND ONE HOUR AND COULD NOT FIND PROBLEM. TIRES ROTATED FRONT TO BACK AND CRISSCROSSED. NOISE STILL THERE.NOISE GETS VERY LOUD AND DOES NOT CHANGE WITH ROAD TYPE.
