What all makes up the strut? is there not a bearing on the top of the strut? What I need to know is to replace the suspension what are the normal items I need to buy to get the job done. Im not worried about removing the struts, and I will replace the end links for sure...but is there a bearing on top of the fronts? and whats on the back struts that normally wear out? Or should I just cost out the four struts to do the job? I got 120k on my car, and Im looking at keeping it say another 10 yrs...
