The 48001-3DN1A Power Steering Rack is a hydraulic steering gear for Nissan compact and mid-size vehicles. 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. According to parts data, the 48001-3DN1A is cross-referenced with multiple OE numbers including 48001-3SG1A, 48001-9AN0A, and 48001-9AM0A . The rack is confirmed for Nissan models including the Tiida (C12) , Sentra VII (B17), and Sylphy (B17) .
For earlier generation Tiida (C11, 2004-2012), note that these models typically use electric power steering (EPS) rather than hydraulic, so this rack may not be compatible . The 48001-3DN1A is applicable to newer C12 generation models with hydraulic systems. This is a direct replacement for the original equipment. Please confirm compatibility with your vehicle using the existing part number and VIN before ordering.
