Wheel Bolts problems of the 2000 Ford Expedition

This 2000 Ford Expedition is used as an emergency response vehicle operated by paramedics responding to 911 calls for medical assistance. During routine driving, a paramedic reported a sudden grinding noise in the front end. He was returning to the station when the front right wheel (tire and rim) came off. All five posts were sheered off. Vehicle undergoes rigorous maintenance, and no previous issues were reported.

While driving at 50 mph heard a pop, rear left wheel bolts came off and studs snapped, and wheel come off.

Left rear tire and rim came off while driving at 60 mph and pulling a small utility trailer, causing an accident. The trailer was severly damaged. The tire, which apparently left the vehicle when several lug bolts sheared off, was retrieved undamaged from a field near the road. The tire had not been removed from the vehicle since it was manufactured. Photos of the accident, sheared lug bolts, and resulting damage are available. This occurred while en route to a youth mission trip in south dakota with six people in the vehicle. There are many witnesses to this accident which clearly appears to have been the result of a manufacturing defect or engineering flaw similar to that encountered with 1997 and 1998 Expeditions.
