      *1 Fulcrum Length
      *2 Turn

      Using SST and a socket wrench, fully tighten the bolt (B).

      SST
      09961-00950
      Torque:
      without SST
      50 N*m  { 510 kgf*cm, 37 ft.*lbf }
      with SST
      35 N*m  { 355 kgf*cm, 26 ft.*lbf }

      Note


      • Use a torque wrench with a fulcrum length of 345 mm (1.13 ft.).

      • This torque value is effective when SST is parallel to the torque wrench.

    6. Slowly lower the rear axle assembly.
