  1. Remove the SST from the transmission.

    SST
    09325-40010
  1. Insert the yoke of the intermediate shaft into the transmission.

    HINT:
    Be careful not to damage the oil seal.

  1. Install the 2 center support bearing washers and center support bearing. (for automatic transmission)

  1. Install the 2 center support bearing washers, center support bearing and 2 center support bearing dampers. (for manual transmission)

  1. Temporarily tighten the 2 bolts.

  1. 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.



  1. 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.


    2. Using SST, measure the installation angle of the differential.

      SST
      09370-50010
      HINT:
      Measure the installation angle by placing the SST in the positions shown in the illustration.
    3. Calculate the No. 2 joint angle.

      No. 2 joint angle:
      A - B = -1°13' to -0°13'
      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'
      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.
  1. Adjust the No. 2 joint angle .

    1. Select the center support bearing washers for adjustment.
