When driving uphill in the rain rear of the vehicle fishtailed when braking.
Stopped at a traffic light and when light turned green, pressed gas pedal but truck would not move. Waited a few minutes and pressed pedal and truck went. Driving down highway, truck started coasting - engine was running but pressing the gas pedal gave no power. Finally got the truck to Ford service. Left the truck running and in park - the truck jumped into reverse. The truck lost power again while the Ford tech was test driving. They replaced the electronic gas pedal and the transmission. They took the truck on a test drive and noticed the rear end was grinding. They determined the carrier bearings had come apart. They have ordered a new rear end. The windshield washer fluid would not spray - they repaired some wiring to correct that problem. Ea04006 has ifs.
