Front Suspension Wheel Bearing problems of the 2012 Ford F-250

When I'm driving down the road I in my 2012 F-250 I get death wobble, the front tires start shaking like crazy and the steering wheel and whole truck shakes like you can't imagine, it starts around 50mph and gets really bad about 60-65mph. I have replaced ball joints,tie rods, shocks, wheel bearings, steering stabilizer, u joints and track bar bushing, none of it fixed it. I can't figure out how to fix it. It about runs you off the road it's so bad sometimes and you have no control of steering wheel.
