      *1 Aluminum Plate
      *2 Wooden Block

      Secure the steering column assembly in a vice using aluminum plates and wooden block as shown in the illustration.

      Note


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

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

      *1 Service Nut

      Install the 2 service nuts to the steering main shaft.

      Recommended service nut
      Thread diameter
      12.0 mm (0.472 in.)
      Thread pitch
      1.25 mm (0.0492 in.)

    3. Simultaneously rotate the service nut that was installed first counterclockwise and rotate the service nut that was installed second clockwise to lock them.

      Note

      Do not apply excess torque to the service nuts by using a tool such as an impact wrench.

      Tech Tips

      These nuts are installed to turn the steering main shaft. They should be removed after inspecting the steering main shaft rotating torque.

    4. A01HVYD

      Using a torque wrench, turn the main shaft and measure the preload.

      Preload
      1.2 to 1.7 N*m (12 to 17 kgf*cm, 10 to 15 in.*lbf)

      If the preload is not as specified, replace the power steering motor assembly or electric power steering column sub-assembly with a new one.
