STEERING LINKAGE INSPECTION

PROCEDURE


  1. INSPECT TOTAL PRELOAD

    Note

    Inspect the total preload in a no-load condition by removing the tie rod assembly RH, tie rod assembly LH and steering rack boots.


    1. B007391N01

      Install SST to the pinion shaft and turn it left and right 5 times or more.

      SST
      09616-00011

    2. Using SST and a torque wrench, turn the pinion shaft continuously at a rate of 4 to 6 seconds per turn to check the total preload of the power steering link assembly.

      Standard Preload
      1.5 to 2.46 N*m (16 to 25 kgf*cm, 14 to 21 in.*lbf)

      Note

      Check the total preload around the steering rack center position.

      If the total preload is not within the specified range, replace the power steering link assembly with a new one.

  2. INSPECT POWER STEERING LINK ASSEMBLY


    1. Disconnect the C1 power steering motor connector.
