• Q: How to Remove and Install the Rack and Pinion in a Steering Gear System on 2002 Toyota Echo?

  A: A proper rack and pinion removal begins with aligning the wheels forward before you eliminate the steering wheel pad and the steering wheel. The first step involves disconnecting the RH and LH tie rod ends after removing the RH and LH engine under covers. Afterward, remove the No. 2 column hole cover. Dismiss the steering yoke alongside pressure and return tubes with Special Service Tool: 09023-12900 and separate the tube clamp via removing its retaining bolt. You should first take off the engine hood before using an engine sling device to hang the engine on hangers while installing the 2 No. 1 engine hangers (Parts No.: No. 1 engine hanger: 12281-21010, Bolt: 91511-60818) with a torque of 20 Nm (200 kgf-cm, 14 ft. lbs.). Disassemble the lower suspension arm from the steering knuckle and from the engine rear mount insulator and front suspension member by removing the bolt and then the 2 nuts. Use the transmission jack to support the combination of front suspension member with lower suspension arm and rack and pinion assembly before removing all 4 bolts that hold everything together. The procedure to remove the rack and pinion assembly starts with uninstalling the stabilizer bar followed by removing the bolt of the rack housing heat insulator and the 2 bolts and then taking out the rack housing heat insulator and dynamic damper and finally removing the column hole cover sub-assembly with its 4 bolts and nuts. Insert matchmarks onto the No. 3 intermediate shaft assembly and control valve shaft before unfastening the bolt and removing the No. 3 intermediate shaft assembly from the rack and pinion assembly. Also discard the bracket and grommet attached to the rack and pinion assembly. Start by using 3 bolts to install the engine rear mount bracket (torque: 49 Nm (500 kgf-cm, 36 ft. lbs.)) before fixing the engine rear mount insulator through its bolt and mounting the No. 2 engine rear mount bracket (torque: 64 Nm (650 kgf-cm, 47 ft. lbs.)). Static reference markings must be aligned between two components for the No. 3 intermediate shaft assembly and control valve shaft before installation of the bolt with a torque of 28 Nm (290 kgf-cm, 21 ft. lbs.) to join the assembly. Then install the bracket and grommet onto the rack and pinion assembly while ensuring that the front of the vehicle faces the designated inscribed mark. Position the rack and pinion assembly onto the front suspension member using 4 bolts and nuts that require torque to 74 Nm (750 kgf-cm, 54 ft. lbs.) and afterward add the column hole cover sub-assembly and dynamic damper with rack housing heat insulator secured through two bolts (torque: 18 Nm (180 kgf-cm, 13 ft. lbs.)) and the remaining installation involves the rack housing heat insulator bolt (torque: 35 Nm (360 kgf-cm, 26 ft. lbs.)). Reinstall the stabilizer bar after you align the holes of the front suspension member with the body using Special Service Tool: 09670-00010 to complete setup with lower suspension arm and rack and pinion assembly by tightening 4 bolts (Bolt A: 116 Nm (1,180 kgf-cm, 85 ft. lbs.), Bolt B: 70 Nm (715 kgf-cm, 52 ft. lbs.)). The procedure continues with the bolt securing the engine rear mount insulator to the front suspension member while using two nuts that require a torque of 80 Nm (810 kgf-cm, 59 ft. lbs.). Afterward, reinstall the lower suspension arm onto the steering knuckle and remove the engine sling device from the hangers of the engine. Attach the engine hood after which you should install pressure feed and return tubes temporarily then add the tube clamp with its bolt tightened to 7.8 Nm (80 kgf-cm, 69 inch lbs.). Use Special Service Tool: 09023-12900 to connect pressure feed and return tubes with a torque setting at 27 Nm (280 kgf-cm, 20 ft. lbs.) while connecting the return hose with the clip along with the column hole cover subassembly. After sliding yoke reinstallation connect the No. 2 column hole cover and proceed with attaching both RH and LH tie rod ends before installing the RH and LH engine under covers. Straighten the front wheels while centering the spiral cable until you can install the steering wheel matching the column main shaft marks prior to torquing the wheel set nut temporarily. Power steering bleeding procedures should follow while inspecting the steering wheel center point before torquing the steering wheel set nut to 50 Nm (510 kgf-cm, 37 ft. lbs.) for subsequent installation of the steering wheel pad as well as front wheel alignment verification.
