Lately ive noticed a noise comming from the rear passanger wheel well. It sounds like rum-rum-rum and is most pronounced at 45 mph. I dont think its a bearing because it does it all the time turning or going straight. I live in NY on Long Island and we have had a most brutal winter. I noticed some scrapes on the rim and am hoping it is not the rim. Ill blame this one on my wife(who knows)any suggestions. cosmedically the rim looks straight and true. a little help would be great. 2000SE great car ****ty gas mileage
