Wheel Bolts problems of the 1999 Ford Expedition

The contact owns a 1999 Ford Expedition. While driving 10 mph, the rear of the vehicle jumped in the air as the rear passenger side tire detached simultaneously. The vehicle was towed to the contact's residence, but was not diagnosed by the dealer. Nhtsa campaign id number 99v099000 (wheels:lugs/nuts/bolts) was referenced. The current and failure mileages were 150,000.

I work at a tire store and have seen on numerous occasions, lug studs snapping with torque wrench use of 100 psi. On Ford and Lincoln trucks and SUV's. It is only happening to the ones with 10 mm lug studs. The metal on the inside of the stud has varying shades of grey in it. It looks like the metal is not the same all the way through. Once the stud snaps, the nut can be screwed off by hand and is not cross threaded. When trying to torque them, the nut keeps turning until the stud snaps. We have done this using different impact guns and torque wrenches on a minimum of 15 vehicles with any where from 1 to 8 studs snapping. The customers think we are breaking them from incompetence. Ford recalled studs from 1997 to 1998. I have seen it on 1999 and 2000 models with 10 mm studs. When I send them to the dealer on the later models, they are told it is not covered.

Normal driving, shaking steering wheel, which lead to a broken wheel stud after it was already fixed in another recall. No injuries, was caught before any damage was done.

While traveling at 45 mph and pulling a trailer down hill, and without any indication, left rear wheel separated from vehicle. Tire/ rim and disc brakes were gone. Please provide further information. The lug blots sheared off causing the wheel to separated from the vehicle, all bolts sheared off at backerplate. Nlm.

Towing boat with the Expedition. Back left rear wheel ran off. Contacted the dealership where I purchase Expedition. Wanted no part of what I had to say. They were contacted three times. Next called Ford @ 1-800-392-3673. Told them I had been made aware of the recall on the wheels/lugs/nuts/bolts. But I was informed my truck was not included in this recall. I asked why did my truck have all the systoms of the recall. 1) wheel ran off 2) none of the remaining 3 wheels will not torque down tight. My truck is also still under warranty but I was told Ford would not take care of the problem without a fee. I feel Ford is at fault, but they do not want to help.

Wheel of vehicle disconnected due to lugs:nuts: bolts shearing off. I was informed (by my brother who is a Ford technician) that night that there is a recall on Ford Expedition for that problem.

Dealer said that cotter pin on right front wheel was missing, an accident did occur.

After having vehicle serviced technician noticed that wheel studs were broken. Consumer contacted dealer, consumer's vehicle did not comply with recall 99v099000 due to VIN. Please provide further information.

1000 miles after a tire rotation, right rear wheel fell off while vehicle was in motion, causing damage to back quarter panel and brake rotor, dealership stated wheel nuts were probably over tightened and caused wheel bolts to break, the other three wheels were checked and found to be tightened similarly, consumer states there gives no mention of recommended torque on the wheel nuts when rotating tires.

While traveling at 25mph lugs: nuts and bolts began loosening. This was noticed as the wheel began to wobble and shake very hard. The consumer pulled over only to notice that the lugs were coming off. The dealer has been contacted.
