Carrier/rack problems of the 2012 Ford F-250

While drive my 2012 Ford F-250 at speeds of 65+, the steering wheel start to shake violently after driving over a bump in the road. I have researched this and found it is commonly known as a death wobble. The videos found on youtube replicate it correctly. I'm not sure what other damage it may have caused to my truck. It has been happening since I bought the truck. I've bought an adjustable track bar and tried many different tires combinations. I have not found a solution.

Ford f250 truck - front end suspension and 4 wheel drive problems. Since March of this year 2016, @ 90k miles, while driving down the road, traveling around 50 mph, the front suspension on my Ford f250 started shaking and wobble uncontrollable. This has happened probably 20 times or so. The wobble was so serious and scary. I would have to apply my brakes and hold onto the steering wheel with a strong grab, to keep my truck on the road. Other vehicles around mine, would scatter out of my way. On October 17, 2016, I had the steering damper replaced and the track bar ball replaced, costing $361. 71. "death wobble", was still happening. Last month on November 14, 2016, I took my truck into our local Ford dealership for repairs on the suspension problem - "death wobble". Repairs included, bar - front suspension ti, joint asy - ball, nut, end asy - drag link rod, rod, rod asy - drag link, adjuster asy @ 2, all replaced with new parts. Replace drag ink and end, install adjusters for castor, front end alignment (4 wheel drive). The Ford dealership was even aware of this existing problem with the Ford f250 suspension, from previous complains and repairs. My repair cost was $1205. 07. Now my 4 wheel drive will not lock in on the front end. I have an appointment, taking my truck back to Ford dealership tomorrow morning for additional repairs. This is a major safety issue on these vehicles and something must be done about it. A recall should and must be mandatory for the public safety. This issue will end up killing someone (if, it has not already) if, a recall is not ordered immediately.

There is no way to secure rear facing infant child seat into vehicle. No clips or rings to attach the carrier to. Seatbelt alone is not sufficient. Infant carrier is equipped with clips on both sides to attach to secure rings at base of seat. My Ford focus has clips for three rear facing sears. Why not the truck?.
