STEERING COLUMN ASSEMBLY INSPECTION

PROCEDURE


  1. INSPECT PRELOAD


    1. A01MH1XC01
      *1 Steering Wheel Set Nut
      *2 Service Nut

      Secure the steering column assembly in a vise using aluminum plates.

      Note

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

    2. Install the service nut and set nut 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 nut 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. 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
      0.9 to 1.7 N*m (9 to 17 kgf*cm, 8 to 15 in.*lbf)

      If the preload is not as specified, replace the steering column assembly with a new one.

    5. Remove the service nut and set nut.

  2. INSPECT BUSHING


    1. A01MHC1C01
      *a Bushing

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

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