Death wobble while driving down interstate going around 50/60 mph. i hit a bump in the road as i was traveling onto a bridge and truck started shaking 'dangerously' out of control. the truck didn't stop shaking until i slowed down to around 30 mph. it was hard to hold truck into highway lanes and i almost hit the guard rail on my right. the truck shook for at least 5 to 10 seconds and after getting back control of vehicle it did the same thing seconds later. this is very dangerous could have caused accident and loss of life!
