My pump is about 2 years old from Advance or Oreilly's. The steering rack is a little over a year old from Ford. Over the last couple of months I've noticed the steering being a little harder to turn. While on a trip out of town yesterday it got a lot worse. I can't turn the wheel at all when the car is stopped and it takes a lot of effort to turn it while its moving. There's not a lot of whine coming from the pump. Which is what I would normally expect if it was going out. Although there is more than there used to be. I hope it's not the rack. That's the biggest pain in the ass work I've ever done on this car.
