| Defect summary | Tiffin is recalling 23 my 2009 allegro buses equipped with arvinmeritor axle assemblies. The wheel end studs may have been improperly tempered rendering them brittle and susceptible to fracture. If one wheel stud fractures, the remaining wheel studs are required to carry more load. If left in this condition, the remaining wheel studs may also fracture even if they are properly manufactured. |
| Consequence summary | Fractured wheel studs could result in a vehicle crash. |
