A method of retrofitting a trailer having a crank jack with a jack housing and a jack leg into a hydraulic jack includes removing mechanical components from within the jack housing, the mechanical components comprising gearing of the crank jack, placing a hydraulic cylinder within the jack housing, wherein the hydraulic cylinder comprises a main cylinder and a ram piston extending outwardly therefrom as the main cylinder is filled with pressurized fluid, securing the hydraulic cylinder by fastening a top portion of the hydraulic cylinder to the jack housing using a fastener inserted through a hole in a platform positioned within the jack housing, and further securing the hydraulic cylinder by fastening the ram piston to the jack leg using a bolt extending through a pre-existing hole in the jack leg.
