The defect
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.
The risk
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.
The remedy
Oshkosh will notify owners, and owners will be instructed to inspect the output shaft, and if necessary, order a new one and replace it, free of charge. The recall began on March 31, 2021. Owners may contact Oshkosh customer service at 1-888-686-7278.
