I have a 1987 Coupe, completely stock, with 72,000 miles on it. I have noticed a noise somewhere between a loud rattle and a clunk coming from the rear end. I have checked the spare tire, electric antenna, struts, or shocks, and mufflers and they all seem to be solid. Does anyone know if there is a specific area I should look at to find the problem? The car seems to handle just fine. I am pretty sure it has to do with the suspension. Thanks.
