I have a clunking sound when going from reverse to drive that has been there since I got it. I think it's getting worse but very gradually. Any of you have this or is it considered "normal"? I can also hear a faint clink from what sounds like the rear axle from inside the truck too but can't tell if that's where it's coming from or not.
Trying to decide if I want to take it in for Ford to look at it or not.
