I have seen someone with this same problem. We were on a SS cruise and ended up parked next to each other. My springs were just installed and his were about a year old. There was a noticable difference. His tires were definitely tucked (G-force). He also said he had rubbing problems. Maybe your rubber isolators came loose/fell out?
I havent read of anyone else with this problem either. But to tell you the truth, his drop looked good.
