• Q: How to remove and install the Rack And Pinion on 2002 Toyota Prius?

  A: A correct removal of the rack and pinion requires that the front wheels remain straight ahead followed by the removal of the steering wheel pad and steering wheel. Begin by removing both engine under covers from RH and LH sides followed by disconnecting lower suspension arm at the ball joint and stabilizer bar and RH and LH tie rod ends. The two connectors and EMPS bracket can be removed by unfastening clamps followed by unbolted the earth wire bolt and EMPS bracket bolts. The No. 2 intermediate shaft assembly needs to be disconnected by matching its assembly and control valve shaft markings and loosening bolt "A" and then removing bolt "B." Next, disconnect the torque rod before removing both the suspension member and electrical power rack and pinion assembly then getting to the electric power rack and pinion assembly itself by detaching the stabilizer bar and securing four bolts to the front suspension member with the further removal of the bracket and grommet. Initially connect the grommet along with bracket to the electric power rack and pinion assembly while making sure the bracket inscription faces forward before secure the assembly with four new bolts reaching 83 Nm (850 kgf-cm, 61 ft. lbs.) torque while reconnecting the stabilizer bar. Secure the main shaft lower dust seal by applying vinyl tape on the serrated part of the control valve shaft and rotating it from engine compartment to cab direction. Install the suspension member together with the rack and pinion assembly followed by connecting the torque rod before securing the EMPS bracket using two bolts torqued to 5.5 Nm (60 kgf-cm, 52 inch lbs.) then complete the procedure with connecting the earth wire using a similar bolt torqued to 5.5 Nm (60 kgf-cm, 52 inch lbs.) while also attaching the two clamps and connectors. Begin reinstallation of the lower suspension arm by rejoining its components to lower ball joint then stabilizer bar followed by No. 2 intermediate shaft assembly while the dust seal remains in position and by removing vinyl tape before aligning matchmarks before tightening bolt "A" to 35 Nm (360 kgf-cm, 22 ft. lbs.). Follow this procedure by joining the RH and LH tie rod ends then measure the front wheel straightness (with jacking preferred) before centering the spiral cable and installing the steering wheel through matchmark alignment and an initial steering wheel set nut tightening. The technician should check the steering wheel center point followed by torquing the steering wheel set nut to 50 Nm (510 kgf-cm, 37 ft. lbs.). Afterward, install the steering wheel pad then check the front wheel alignment and perform torque sensor zero point calibration.
