It actually is all original, which i was surprised about, since my 5 series need a suspension refresh at 100k. What do you think I should replace?. my CV's are fine, so control arms and possibly tie rods? Or do you think the Wishbone and struts with mounts? I do all my own work. But I broke my shoulder bone 3 months ago so I don't have the strength to work on everything at one time.
