I have 110,000 miles on my 1998 csvt and recently i have been getting a noise from the rear of my car it sounds like a spare tire bumping up and down? but all is secure i have checked exaust brackets every thing but then i look in my wheel well and see my strut is leaking fluid and look at my other rear one and see the same thing . after seeing that i wen't driving every time i hit a small bump with the rear tires it makes the noise and then is fallowed by a small wave of concussions like vibebrations i am going to replace my struts is there anything else it could be so i can fix it while it is takin apart. also im getting the bat struts are those better than stock ones or not?
