Introductions: The steering column consists of three major components, a steering shaft, a shift tube, and a column or mast jacket. The steering shaft connects the steering wheel to the steering gear unit through a universal joint type coupling. The steering column is for connecting the steering wheel to the steering mechanism by transferring the driver's input torque from the steering wheel. The power steering pump/vane pump, is a system driven by the movement of the crankshaft by means of pulley and belt. Steering components are designed to maneuver the car easily and in the direction indicated by the steering wheel.Feature: Brand New 2 years warrantySpecification 1990 - 1997 for Lexus LS400 All Models OEM Number or Interchangable Part Number 4432050010 , 44320-50010 , 4432050020 , 44320-50020Package includes: 1x Power Steering Pump with ReservoirCode:MGGRP Authority IDMXR02FXSY NoticeCalifornia Prop 65 Warning Notice NoticeCalifornia Prop 65 Warning Code:MGGRP Return Policy All of our items come with a 30-day free return policy.
