Ok if I was to go onto KYB website to look for struts for my car whether they have AVS option or not. Is the strut the only thing i need to do i need to get anything else. THe car creaks and knocks over bumps. Is there more parts to the Strut assembly that can go bad other than the spring and strut, like any other top or bottom pieces. I am very confused, I had an 84 Buick lesabre and the car was easy to work on, if the shock was bad, Boom you change the shock. things were a lot easier, now i'm just completely confused.
