The present invention discloses a drill rig relocation system. Lift frames are provided as add-ons to existing drill rigs, or as integral openings within the length of the base boxes. A lift cylinder and bearing mat assembly is connected beneath the lift frame or base boxes. Each bearing mat assembly has a slew drive for controlled directional rotation. A torque arrest system allows vertical movement of the torque reaction point as the substructure is elevated to control the orientation and magnitude of forces. In one embodiment, the drill rig is supported on linear sleeve bearings slideably mounted in the bearing mat assemblies. Translation cylinders on the bearing mats expand to move the drill rig by translating the linear sleeve bearings along the shafts.
