Defect
It is possible that the rear suspension may collapse during riding due to the bearing installation part of the suspension arm breaking. It could become damaged by a stress corrosion crack that is caused by a remaining stress at the bearing press filling part and a corrosive attack on the surface of the stressed area by a corrosive agent such as that which is used to melt snow.
