Installation [12/2019 - 10/2022]: Procedure

  1. INSTALL TRANSFER ASSEMBLY 
    1. Temporarily install the transfer assembly to the transaxle with the 8 nuts.
      NOTE:
      • Push the transfer assembly by hand until it is in close contact with the mating surface of the transaxle assembly.
      • If the entire mating surface does not come into close contact, tighten the nuts alternately in the order of nut A and nut B, and bring the mating surfaces into close contact little by little.
      • Make sure the mating surfaces of nut A and nut B are in close contact. Then temporarily tighten the nuts in order as follows and bring the entire circumference of the mating surface in close contact.

      HINT: 

      Temporarily install order: Temporarily install nut (A) → Temporarily install nut (B) → Temporarily install nut (C) → Temporarily install nut (D) → Temporarily install nut (E) → Temporarily install nut (F) → Temporarily install nut (G) → Temporarily install nut (H)

      *a Union Nut Wrench
      *b Torque Wrench Fulcrum Length
    2. Using SST and union nut wrench, tighten the 8 nuts.
      • SST: 09961-00950 

      Specified tightening torque 

      Torque: 68.6 N.m (700 kgf/cm, 51 ft.lbf) 

      HINT: 

      • Tightening order: Tighten nut (A) → Tighten nut (B) → Tighten nut (C) → Tighten nut (D) → Tighten nut (E) → Tighten nut (F) → Tighten nut (G) → Tighten nut (H)
      • This torque value is effective when SST is straight to a torque wrench.
      • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

        Refer to PRECAUTION [12/2019 - 11/2023]

      • When using a union nut wrench (fulcrum length of 30 mm (1.181 in.)) + SST (fulcrum length of 150 mm (5.906 in.)) + torque wrench (fulcrum length of 255 mm (10.039 in.)): 40.2 N.m (410 kgf/cm, 30 ft.lbf)
  2. INSTALL REAR ENGINE MOUNTING BRACKET SUB-ASSEMBLY 

    Refer to PROCEDURE - Step 9 [12/2019 - 09/2020] , or refer to PROCEDURE - Step 9 [09/2020 - 10/2022]

  3. INSTALL AUTOMATIC TRANSAXLE ASSEMBLY 

    Refer to INSTALLATION [12/2019 - 09/2020] , or refer to INSTALLATION [09/2020 - 10/2022]

  4. DYNAMIC TORQUE CONTROL AWD SYSTEM CALIBRATION (for Dynamic Torque Control AWD) 
    1. When the front 4WD linear solenoid (transfer assembly) is replaced, Learning Value Initialization must be performed.

      Refer to CALIBRATION [12/2019 - ]

  5. DYNAMIC TORQUE VECTORING AWD SYSTEM CALIBRATION (for Dynamic Torque Vectoring AWD) 
    1. When the front 4WD linear solenoid (transfer assembly) is replaced, Learning Value Initialization must be performed.

      Refer to CALIBRATION [12/2019 - ]
