Wheel Bolts problems of the 2000 Ford F-150

Left rear wheel fell off the pickup. Damaging rear disc and axle. I was going approximately 45 mph when this happend. The vehicle has had a vibration problem at 65 mile ph varing in intensity. The dealer replace the drive axle, wheel, caliper/disc and brake lines free of charge. Teh vibration at 65mph still continues. The dealer has stated the vibration is within allowable limits as etermined by the manufacturer. I have heard other have had the same problem with this 2000 f150 5. 4 l abs 4 wheel disc brake vehicle with tow package. Mileage was 25,863 VIN #1ftxr17l4yka54748.

While traveling eastbound on freeway, left rear wheel flew off truck, over concrete median barrier into westbound traffic. An accident subsequently ensued in westbound lanes involving pregnant woman. Three of the five studs failed resulting in wheel assembly pulling away from remaining two studs and flying off the vehicle. The dealer refused to repair the damage to the truck resulting from this failure even though the truck was still under original warranty, and even though no work was done on wheel or tire other than by manufacturer or dealer prior to sale.
