A rig movement and rotation assembly, which includes a first pair of vertical lifting jacks and a second pair of vertical lifting jacks. Each of the vertical lifting jacks has an upper end connected to a rig substructure and a lower end. A roller assembly is connected to the lower end of each of the vertical lifting jacks with each roller assembly rotatable on an axis. A steering cam arm bracket extends from each roller assembly. A first connecting link joins the steering cam arm brackets from the first pair of lifting jacks together and a second connecting link joins the steering cam arm brackets from the second pair of lifting jacks together. An actuator extends or retracts the length of each of the connecting links. A skid jack for each of the vertical lifting jacks engages with the roller assembly.
