I am having trouble isolating the source of a low-pitched "thrumming" sound coming from the rear wheels of my 1989 Sable. The frequency of the sound is proportional to wheel rotation speed. Because one of the rear wheels was out of alignment, I replaced the tire on that wheel, but the sound is still there. The only other clue I have is that the sound gets louder when cornering. Is this a bearing problem? Could the other wheel/tire be at fault? What should I check next?
