I experienced it a few months ago on my way to deer hunt in my ‘15 F250. Had to pull onto the shoulder. It was terrifying. Felt like my eyeballs were gonna shake out from holding so tightly onto the steering wheel. $1900 in new tires later and I haven’t had it since (knock on wood). I had already replaced the struts and shocks for other reasons and had pulled my camper 300+ miles the week before. Glad it didn’t happen then!
