STEERING COLUMN ASSEMBLY INSPECTION

PROCEDURE


  1. INSPECT PRELOAD


    1. A003OPTC01
      *a Wooden Block
      *b Cloth

      Secure the steering column assembly in a vise using aluminum plates, cloths and wooden blocks.

      Note


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

      • Support the steering column assembly with wooden blocks or similar items to ensure that it does not fall.

    2. A003MQFC21
      *a Service Nut

      Install 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 excessive torque to the service nuts by using a tool such as an impact wrench.

      Tech Tips

      The service nuts are used for turning the steering main shaft during inspection of the steering main shaft rotating torque.

      Remove the service nuts after performing this inspection.

    4. A003O37

      Using a torque wrench, turn the steering main shaft at a constant rate of approximately 1 revolution every 4 seconds and measure the preload.

      Preload
      1.1 to 2.3 N*m (12 to 23 kgf*cm, 10 to 20 in.*lbf)

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

    5. Remove the 2 service nuts.

  2. INSPECT STEERING COLUMN ASSEMBLY


    1. A003P50

      Check that the 2 bushings are securely installed to the steering column assembly.

      If the bushings are deformed, missing or damaged, replace the electric power steering column sub-assembly with a new one.
