Some 2019 Transit vehicles built on 1-Oct-2018 and through 31-Jul-2019 with aluminum alloy single rear wheels (SRW) may exhibit broken rear wheel stud(s). This may be due to variation in the axle flange to wheel mating surface of the axle shafts. To correct the condition, follow the Service Procedure steps to replace both rear axle shafts and all rear lug nuts.
