The lippert hydraulic jack/leveling jack sand pads are held on by a bolt that is tightened to a specific torque level. Some have had them loosen or fall off like yours apparently did. I believe red thread lock is recommended when they are installed by the manufacturer. A few have had them loosen and owner has retightened only to have them eventually fall off if the thread lock isnít used. I would search www.LCI1.com
and look for torque specs for these sand pads. Pretty sure they can sell a replacement foot and bolt also. Sorry for your loss.
