I noticed a grinding noise coming from the front end of my truck. I could also feel the grinding though the steering wheel. I took it to local Ford dealership. They told me that it was the steering gear rack/pinion. I reported the problem to Ford and they declined to help with the repair cost and did not acknowledge the problem.
