Steering froze and I could not turn left. We were driving into town from the lake, pulling our boat. Began to notice the truck was not allowing me the adjust left and about 5 minuyes later we could not turn left. I pulled as a hard as I could and could only move the wheel about 1 inch left. Next day the radio display screen said something about power steering system. I took the truck to mckie Ford in rapid city sd by driving only where I could turn right. Ford dealer replaced the steering gear and charged me $1500. And no guarantee the "new" epas gear box won't fail. Very frightening to be driving and not be able to move or turn left! and I see Ford has started recalling some of there vehicles with this same system. How can they recall some not all? in hindsight, there was a sympton for about 2 years: when driving through a left curve the truck would "buckle" or kick ever so slightly to the right as if the tie rod was loose. I took it to the Ford dealership a couple times and they were unable to tell me why it was doing that.
