I have had my Limited since the first of December and I have noticed when it is below freezing out my truck makes a loud humming noise at 2000 RPM going down the highway. It gets louder the longer you drive it at that speed and it seems to vibrate the floor under my left foot also. it takes about a half hour of driving down the freeway to start humming and the longer I drive the louder it gets. I do have 392 gears in my truck so it goes down the freeway at 2000 - 2100 at 75 miles per hour. it does seem like the colder it is the worse it is.
