   -

   1. Using SST, tighten the tie rod assembly LH lock nuts.
      • SST: 09612-24014 

      Specified Tightening Torque 

      Torque: 88 N.m (897 kgf/cm, 65 ft.lbf) 

      HINT: 

      • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

        Refer to PRECAUTION [11/2021 - ]

      • When using SST (fulcrum length of 52 mm (2.05 in.)) + torque wrench (fulcrum length of 255 mm (10.04 in.)): 73 N.m (744 kgf/cm, 54 ft.lbf)
