I realize this is an older post, but no one responded to you. I'd recommend spring changes if they appeared cracked. I just found my driver side rear spring broken in my 13 Taurus SEL. See the pic. I need to inspect my right side spring closer. At a quick glance, I didn't see it cracked, but I'm thinking it may be too, because I have some noise over trashy roads/bumps and it seems to be coming from the right side. I just can't believe that springs of this diameter would just break like that. Of course, in Ohio we get the lovely winter road salt, but should I be experiencing broken rear springs?!? Anyone else experience this in their later model Taurus?I will be putting in new KYB Strut Plus fronts and Excel-g rear struts. Should I change the rear springs and mounts at the same time?
