Ford F-150 Flat tow wobble

[4B77]

I flat tow a 2016 Ford F-150 XLT 4wd. It has flat towed flawlessly until the last few months. Twice, after making a hard left turn, the truck will wobble violently until I can come to a stop. I can then proceed and all is fine. Has anyone experienced this problem and any suggestions as to the cause.

Yes, sticking brake caliper on the truck.
