Two problems related to steering is tight have been reported for the 2017 Ford F-250. The most recently reported issues are listed below.
Loss of control at speeds greater than 50 mph after running over a pothole or rough road surface. The front tires start to bounce or oscillate and steering becomes dangerously erratic. You have to immediately hit the brakes hard to lower the speed. Everything loose in the cabin can begins moving around and the steering wheel is hard to hold. If you are in heavy traffic at speeds of 60-70 mph there is very real danger of being hit from behind while trying to regain control of the vehicle. Descriptions online of Ford f250 trucks call it the death-wobble.
While driving at normal highway speeds on an interstate highway, I hit a minor bump in the road and the vehicle started vibrating radically. The steering wheel was extremely hard to control from the front end bouncing. I had to brake rapidly and pull to shoulder under pretty crowded traffic conditions and it didn't stop until almost completely stopped. It did this numerous times on a out of town trip and I took it to my dealer immediately on my return. The date entered is the first time this occurred. It has happened numerous times since then & has been back to dealer 3 times for this. It is at the dealer now.
