The invention provides a rear wheel steering gear assembly and a vehicle with the rear wheel steering gear assembly. The rear wheel steering gear assembly comprises a shell; the lead screw main shaft is arranged in the shell; the lead screw nut is connected with the shell, and the lead screw nut is located outside the lead screw main shaft; the planetary roller is connected with the lead screw main shaft and the lead screw nut; flange seats are arranged at the two ends of the lead screw nut in the axial direction, first axial bearings are arranged between the two axial ends of the lead screw nut and the inner side walls of the corresponding flange seats, and a pre-tightening gasket is arranged between the outer side wall of at least one of the two flange seats and the shell. A second axial bearing is arranged between the outer side wall of the flange seat and the inner side wall of the pre-tightening gasket, the pre-tightening gasket is made of elastic materials, and a corrugated structure is arranged on the surface of at least one of the inner side wall of the pre-tightening gasket and the outer side wall of the pre-tightening gasket. According to the rear wheel steering gear, the problem that a rear wheel steering gear in the prior art is complex in structure is effectively solved.
