Just bought a 2004 Supercrew F150, and have noticed a slight vibration between 35-45 mph, then back to normal smooth ride. I already have 1,250 miles on it. Is it to late to report it, or take it in, since I haven't said anything to the dealership about it? I thought it would go away after the break in period, but it continues. It is really bothering me now, and have noticed other people have had the same problem.
What shall I do???
