the stuff mechanics see. My god

I worked in a Ford Truck dealership, and we had a F450 come in brand new truck, and it had been to a shop to have a body put on it, so it comes in for a low brake pedal. I test drove it and yea the brake pedal was almost on the floor I looked it over and jacked it up and found the one of the front wheel bearings loose, so I pulled the wheel and found the rotor had rubbed into the spindle because someone at the factory had forgot to put a inner wheel bearing in the hub. Side note the truck had almost 1000 miles on the odometer most likely from being driven to the body builder and back.
