The invention belongs to the technical field of aviation test stands, and particularly relates to a three-degree-of-freedom aircraft landing gear replacing device and method. A three-degree-of-freedom aircraft landing gear replacing device comprises a main stand column, a hanging basket is slidably connected to the inner side of the middle of the main stand column, a guide rail base is arranged on the inner side of the bottom of the main stand column, two linear sliding rails parallel to the heading are arranged on the upper portion of the guide rail base, a vehicle body is slidably connected to the linear sliding rails, and a hydraulic lifting mechanism is arranged on the lower portion of the vehicle body. A lifting table is arranged above the hydraulic lifting mechanism, multiple sets of sliding plates are arranged above the lifting table, sliding seats are arranged on the upper portions of the sliding plates, undercarriages to be replaced are installed on the upper portions of the sliding seats, and sliding seat driving mechanisms are arranged on the side faces of the lifting table and drive the sliding seats to move in the horizontal direction perpendicular to the heading direction. The undercarriage can be fixed, the positions of the undercarriage in three directions can be freely adjusted, rapid replacement of the undercarriage is facilitated, the undercarriage replacement time is saved, the efficiency is improved, and the personal safety of operators in the replacement process is guaranteed.
