REAR PROPELLER SHAFT ASSEMBLY (for 4GR-FSE): Installation

  1. INSTALL PROPELLER SHAFT WITH CENTER BEARING ASSEMBLY 
    1. Remove the SST from the transmission.

      SST 09325-40010 

    2. Insert the yoke of the intermediate shaft into the transmission.

      HINT:

      Be careful not to damage the oil seal.

    9. Tighten the 2 bolts.

    Torque: 49 N*m (500 kgf*cm, 36 ft.*lbf) 

  2. INSPECT AND ADJUST BOTH NO. 2 AND NO. 3 JOINT ANGLES 
    1. Stabilize the propeller shaft and differential.
      1. Turn the propeller shaft several times by hand to stabilize the center support bearing.
    2. Check both the No. 2 and No. 3 joint angles.
      1. Using SST, measure the installation angle of the intermediate shaft and propeller shaft.

        SST 09370-50010 

        HINT:

        The SST should be set directly on the bottom of the shaft.

        SST 09370-50010 

        HINT:

        Measure the installation angle by placing the SST in the positions shown in Fig 7.

      3. Calculate the No. 2 joint angle.

        No. 2 joint angle: 

        A - B = -1°13' to -0°13' (2WD) 

        A - B = -0°53' to 0°07' (4WD) 

        A: 

        Intermediate shaft installation angle 

        B: 

        Propeller shaft installation angle 

      4. Calculate the No. 3 joint angle.

        No. 3 joint angle: 

        B - C = 1°30' to 2°30' (2WD) 

        B - C = 1°26' to 2°26' (4WD) 

        B: 

        Propeller shaft installation angle 

        C: 

        Differential installation angle 

        HINT:

        If the measured angle is not within the specified range, adjust it with the center support bearing washers.

    3. Adjust the No. 2 joint angle.
      1. Select the center support bearing washers for adjustment.
