2004 Ford Explorer Sport Trac Other or unknown Problems

“Vehicle was making a whinning noise from front end at 60 MPH. I checked tires in front and noticed excessive wear on the inside of both tires, the mileage was 25650.I had the alignment checked at a local tire and lube and they could not find any alignment problems. Suggested rotating the tires,these were the tires that came with the vehicle, tires were rotated.however, at about 31000 miles the noise was back and the tire wear was back again, excessive wear. I bought new tires at this time, they have been rotated a every oil change and the problem persist. …”

“I was leaving my friend's house to drive approximately 2 miles and when I went to park my truck which is a 2004 Ford Explorer Sport Trac xlt, the gear shifter was very loose going into park, but did not engage because I was still rolling back, I then proceeded to put on the emergency brake. I turned off my truck and then started it again and this time my truck will not turn over and the shifter is still extremely loose. I looked on several forums and they all say that I might have to replace my steering column, and as far as my truck not starting, I don't know.”
