Toyota 44250-42120 Power Steering Rack Assembly

The Toyota 44250-42120 is a hydraulic power steering rack and pinion assembly designed for the first-generation RAV4 (XA20 chassis) produced from 2001 to 2003. This component converts rotational steering wheel input into linear motion to steer the front wheels, utilizing engine-driven hydraulic pump assistance for reduced steering effort. The assembly integrates the rack bar, pinion gear, hydraulic cylinder, control valve, and tie rod ends into a single unit. It features a left-hand drive configuration with metric flare fittings for high-pressure and return lines. The rack uses a variable-ratio design for improved maneuverability at low speeds and stability at highway speeds. OEM cross-references include 44250-42080, 44250-42040, and 44200-42120. Aftermarket interchange numbers include TRW JRP1143. This part supersedes earlier 2000 model year racks and fits vehicles equipped with the 2.0L 1AZ-FE inline-four engine.
