What’s wrong with it?
A fractured rear output shaft may cause the shaft or interaxle driveline to detach from the vehicle, increasing the risk of a crash or injury.
Oshkosh Corporation (Oshkosh) is recalling certain 2020-2021 S-Series vehicles.
The rear axle output shaft may not have been heat-treated properly, which could cause the shaft to fracture.
