Steering Rack And Pinion problems of the 2010 Ford F-150

My truck wonders all over the road and shakes to the point that the passenger is sick. Hard to steer out of ruts and crosswinds blow the truck in to the next lane and you can't control it. Can't take your eyes off the road in front of you to even look at the exit signs because the truck is unsafe and unpredictable to the point that your hands are going to turn numb from lack of blood in your fingers due to the white knuckles from hanging on to the steering wheel so tight. Very unsafe. I have taken it in to the dealer 4 times now and they have replace both front springs and struts and have replaced the rack and pinion 2 times now. I was told that the factory tires are not that great and have soft side walls and that could be the reason as to why it's not fixed and the Ford shocks are under rated for the vehicle. So I have put new bilstien 5100 shocks on all the way around and have put better tires and wheels on it. Truck still does the same thing. This truck is unsafe and have read other complaints on here. Here are the other complaint #'s. 10392353, 10407502, 10336730. I just can't believe Ford has not acknowledged any of the complaints on this site. Someone is going to die or burn to death and I hope it's not me or my family. The only recall I can find on this truck is the door handle and was told it doesn't pertain to my truck. I would like to file for a class action lawsuit if anyone is interested because I know I am not the only one out there who is afraid to drive their $46,000 truck that's not even 2 years old yet. This truck was suppose to be built Ford tough. I will be trading this p. O. S in as soon as I can cough up all of the negative equity that I have acquired due to the high price of this lemon. I have said my peace and now it's on file just in case I crash and burn, at least I know my family will be taken care of now (I hope).
