The drive shaft universal joint bearing may not have been properly assembled and, even if properly assembled, may not be sufficiently durable as a result of manufacturing errors. As a consequence, the universal joint may, in the worst case, break and interfere with the swing arm causing the rear wheel to lock-up. This may result in a crash.
