Power Steering Pump problems of the 2006 Ford F-350

Truck has a steering problem. Most of the time truck travels strait. Some times after making a turn right or left the truck continues travel in that direction! I have to yang hard on the steering wheel back in opposite dirrection to get truck back in its lane!also sometimes the truck out of the clear blue truck take off to the right or left an I have t pull the wheel in opposite direction to get truck back in it's lane!other times going than the road the truck hits a bump in the road an truck will either go right or left an steering wheel has to be pull the opposite direction to get it back in it's lane! I notice this same problem has been reported before an no one has been able to fix it! mechanics say it's the steering pump or steering box which has not corrected any body's truck that that has both these parts replace! this can cause a major accident Ford should fix this problem.

The initial occurrence in December 2011 was a steering stick in the direction of the turn and required force to turn opposite the direction of the turn. The problem ceased and did not reoccur until mid-may of 2012. The problem manifested itself as a severe oscillation of the vehicle steering accompanied by directional sticking and "indexing" in the steering. The first attempt at repair was to flush the power steering system. This actually resulted in a worse oscillation. The problem was still intermittent but occurring more frequently. The dealer was unable to duplicate the problem and I asked for the steering gear to be replaced. This did not solve the problem. The next step was to replace the steering damper. This also did not result in elimination of the problem. During the damper replacement it was noted that there existed a very small amount of play in the dragling ball joint. While not particular out of the acceptable range we agreed to replace the drag link. The drag link has been replaced and the vehicle continues to demonstrate a "walking" motion requiring the operator to actively steer the vehicle to remain in a lane. In addition, the vehicle will demonstrate relatively good stability in a sweeping turn until the wheel is displaced beyond roughly 5 degrees at which point the steering displays an active pull in the direction of the turn. The vehicle is being returned to the dealer for continued evaluation. The Ford technicians have examined and passed the power steering pump, the hydroslave system, front tires, front tire pressure, front ball joints as well as the front axle u-joints. At this point, they have no further suggestions as to the cause of the problem.

I have a 2006 Ford f350 4 wheel drive single wheel long bed king ranch. I will be driving down the road or interstate anywhere between 30 and 80 miles an hour, and if you hit the smallest imperfections in the road the truck will start shaking violently, uncontrollable, the steering wheel moves about 14 inches side to side so fast and hard, that it takes ill I've got to hold on to the wheel. You can hear the tires chirp side to side on the pavement it wobbles so severely. I've replaced the steering dampener, the power steering pump, had it aligned 4 times, brand new tires, I have adjusted the castor accordingly to Fords TSB forum, had my rotors turned, and wheels and tires balanced so many times. Its so bad, it shakes the stuff in the bed of my truck onto the highway. My truck only has 92,000 miles on it. Im afraid to drive it. All I know is that I didn't pay 64,000 dollars for a truck that I cant drive. I will spend the money to fix it, but Ford says its a normal condition.

2006 Ford f350 4x4 steering problems. Dealer authorized 2" revtek leveling kit installed on front end. Stock 20" wheels and tires. Only Ford dealer maintained since new. Steering is inconsistent. Two problems. First: serious safety issue. At highway speeds truck will veer left crossing centerline. Requires excessive steering effort to correct, which frequently results in overcorrection to right. Power steering effort appears in increase and decrease during events. Incident requires letting off the gas and slowing to get vehicle back in control. Second: after low speed 90 degree turns (left or right turn at an intersection in town) steering will not want to straighten out and requires excessive effort. Frequently, after straightening out truck will veer in opposite direction. At low speeds vehicle is controllable with effort. Just spent another $741 at Ford dealer on new power steering pump, rotate, balance, alignment. Problem was not fixed.
