Bump steer??

I have a '15 F350 Super Duty with 28k miles on it and it runs and drives fine. Recently I made a trip to Oklahoma and hit a couple of rough spots on the Will Rogers turnpike. At 70 mph I about lost control at those patches. It seemed to have quite a bit of bump steer and got terribly unstable. The steering wheel is straight, truck tracks straight, and it does not pull left or right.

I guess I could have a shock problem but I've seen these go a lot more miles before needing replaced.

Anyone have any suggestions or having the same issues?

FWIW, coming back I never had a issue but I did not hit a severe rough patch like I did going down.

Maybe the bumps were timed just right to throw the steering off?

Kind of like how washboard dirt roads are created by the shocks of vehicles getting into sync with the bumps making them deeper and deeper?

fyi.. factory stock shocks. suck , at 25k they are tired....... look into good shocks

and stock size tire/wheel.. or up in size...
might get a good steering damper if you went up in size.
