alright so i have been hearing this ever so annoying sound whenever i hit a bump that is like a thud almost like a rattle not really that loud and is coming from the back of the car. at highway speeds i do not hear any noise. at 78k miles i installed eibach sportlines and i am now at 85k miles on the stock struts and wondering if my struts may be blown? i thought the noise was coming from the rubber boot that goes on top of the strut but i replaced them and the noise still continues. any help will be appreciated thanks
