Just bought a 2006 Mustang GT that had the Eibach pro lowering springs installed.......when turning the wheel there is a 'creaking noise' mainly at low speeds...
could it be the rubber insulators were not installed or?
From Steeda's website "These upper mounts eliminate the "popping" sound that is common on lowered cars when the factory upper mount fails". Sounds like you might need to upgrade the upper strut mounts.
