NHTSA recall 79V208000
Wheels
Ford F100 and 1 more
The defect
A number of wheel assemblies on the involved vehicles may have substandard welds in the area where the disc IS attached to the rim. Substandard welds can cause cracks to occur in the wheel assembly. Rapid loss of air pressure in the tire or separation of the wheel rim from the disc could result.
The remedy
If separation and loss of air occurs while vehicle IS in operation, loss of vehicle control and an accident could occur without prior warning. Corrective action: the dealer will inspect and, if necessary, replace the wheels without charge to owner.
