I had vibration as well at speeds of 70mph or above; however no slop in the steering. Had the wheels road force balanced and the vibration remained. Replaced all (4) LCA's and the vibration was gone. Apparently the bushings or ball joints had deteriorated enough to cause the vibration without any noticeable clunking. I then upgraded to the RoW M030 suspension and it felt like a brand new car.
