      Note

      First wipe off the existing grease from the serrated part, and then apply the dedicated grease supplied with a new power steering motor assembly or electric power steering column sub-assembly.

    2. Using "TORX" socket wrench T40, temporarily install the power steering motor assembly to the electric power steering column sub-assembly with the 2 bolts.

      Note

      When temporarily installing the 2 bolts to the power steering motor assembly, do not tighten them all the way down.

      *1 Wooden Block

      Secure the steering column assembly in a vise using aluminum plates and a piece of cloth.

      Note


      • Do not overtighten the vise, as the steering column assembly may become deformed.

      • Secure the power steering motor assembly so that it is directly upright.

      • Support the steering column assembly with a wooden block or similar item to ensure that it does not fall.

      *1 Wooden Block

      Using SST, measure the turning torque of the steering main shaft.

      SST
      09616-00011
      Torque:
      Turning torque
      1.45 N*m  { 14.8 kgf*cm, 12.8 in.*lbf }
      or less

      Note

      Ensure that there is no abnormal resistance during rotation.

      If the torque is not as specified, readjust the axis centering of the power steering motor assembly.

    7. Install 2 new clamps and tape to the wire harness as shown in the illustration.

      *1 Power Steering Motor Wire Harness *2 Torque Sensor Wire Harness
      *3 Tape A *4 No. 3 Clamp
      *5 Tape B *6 No. 2 Clamp
      *a 358 to 378 mm (1.18 to 1.23 ft.) *b 152 to 168 mm (5.99 to 6.61 in.)
      *c 60 to 100 mm (2.37 to 3.93 in.) *d 80 to 120 mm (3.15 to 4.72 in.)
      *e 373 to 393 mm (1.23 to 1.28 ft.) *f 115 mm (4.53 in.)

      Note

      Wrap the tape at least 1.5 turns.

    8. A01UXT0

      Pass the torque sensor wire harness through the cutout of a new protector.

    9. A01UXZ7

      Engage the clamp and install the protector to the steering column assembly.

      Note

      Make sure the wire harness is not pinched between the protector and the steering column assembly.

    10. A01V1YR

      Engage the No. 2 clamp and install the wire harness to the protector.

    11. A01UYHLE01

      Pass a new No. 1 clamp through the groove in the protector, and tighten it within area A shown in the illustration to secure the protector and the wire harness to the power steering motor assembly.

      Note

      Make sure there is no rattling or looseness in the protector.

      Tech Tips


      • Fastening power for No. 1 clamp: 200 N (20 kgf, 45 lbf)
