I have a 05 Ford f150 and my diferential has gone out and needs to be rebuilt I had this issue while under warranty but Ford always found excuses and now that its out of warranty I started to research and I have found alot of complaints where people complain of loud noise and vibrations at the above speeds of 45mph.
While driving on highway @ 60mph, my 4 wheel drive activated without my touching the dash control. The front axle made terrible grinding noises and the vehicle slowed dramatically. Dealer told me it was a vacuum line and Ford replaced under warranty.
