The 49001-8H900 Power Steering Rack is a hydraulic steering gear for the Nissan X-Trail T30 (2001-2007). Also known as a steering rack, steering gear, or rack and pinion assembly, this component converts the rotational motion of the steering wheel into linear motion to turn the front wheels, with hydraulic assistance to reduce steering effort .
This steering rack is specifically designed for left-hand drive (LHD) vehicles, as confirmed by multiple parts catalogues . The T30 X-Trail uses a hydraulic power-assisted rack-and-pinion steering system, as documented in the Nissan X-TRAIL T30 Factory Service Manual .
