1981 Mercedes Benz 240d 145k miles, runs well except for thumping noise coming from back end. Noise sounds like a flat tire but isn't. Thumps at lower speeds then dissapates, then reappears at higher speeds then also when decelerating. So not sure if this is common prob with wheel alignment, or something worse with transmission. Ive been told these cars dont have CV joints, but it sounds similar to that prob with other car I owned. Obviously my mechanical knowledge if very limited. Will have it diagnosed soon by mechanic, but any advice or info would be greatly appreciated. Thanks.
