    Patience. This isn't something that's common, at all. Have a look at the Speed Sensitive Steering, to start with. Check for BCM codes, too.

    I've had issues with a 6.5 where I had to crack open the pressure line that runs from the hydroboost to the steering box to get fluid flow. Once I did, the steering was great. But it had locked for some reason that years later never returned.

    I would use a wrench and just see if fluid is going through the pressure line going to the steering box. It could just be pumping everything to the return.

    Happened to me. I was told to put it in park with the engine running and push the accelerator pedal down to rev the engine some. It cleared up. Then I flushed the system with new fluid.
