What is the torque spec for the wheel bearing nut for a 2006 Ford f150 because when at high speed the truck rattles at 70-75 mph what is the cause of that

do you mean the small 13mm nut that holds the the CV shaft in the hub ? 20-25 foot pounds

You don't say if this is 4wd . Not clear if you are talking about the large nut on wheel bearing That one is 295 foot pounds one time use nut . It is torque to yield and you don't want that one to give out going down the road . They are like $14 each .
You should be looking at ball joints, sway bar ends, and control arms and all the bushings .Jack it up and pull on tires to see if you are getting play .Look for broken coil springs .
I am kinda vague on rattles at speed ???
