On certain vehicles, the lower screw connection of the rear struts to the chassis may fail. The head (Top) of the screw securing this connection may break. The remaining portion of the screw will still hold the strut in place. If left unattended over a period of time, and depending on driving conditions, the remaining portion of the screw may break.
