  6. INSPECT FOR EXHAUST GAS LEAK

  7. INSPECT AND ADJUST JOINT ANGLE


    1. If any vibration or noise occurs, perform joint angle check as follows and replace the No. 2 center support bearing washer with a proper one.


      1. Turn the propeller shaft several times by hand to stabilize the center support bearings.

      2. Using a jack, raise and lower the differential to stabilize the differential mounting cushion.

        Note

        Measure the joint angle while the vehicle is lifted using a 4 pillar lift or while working in a pit.

      3. Remove the transfer dynamic damper.

      4. Using SST, measure the propeller shaft installation angle (A) and intermediate shaft installation angle (B) as shown in the following illustration.

        A01EJ7SE01
        No. 1 joint angle
        (A) - (B) = -3.69° to -1.69°
        Text in Illustration
        *1 No. 1 joint angle
        *2 No. 4 joint angle

      5. Using SST, measure the rear propeller shaft installation angle (C) and rear differential installation angle (D) as shown in the preceding illustration.

        No. 4 joint angle
        (C) - (D) = 1.63° to 3.63°

      6. If the calculated amount is not within the specification, adjust it with the No. 2 center support bearing washer.

        Note


        • Make sure to use a washer of the same thickness on both right and left sides.

        • Do not use 2 or more washers on a bolt.

          Washer Thickness
          Thickness mm (in.)
          3.2 (0.126)
          4.5 (0.177)
          6.5 (0.256)
          9.0 (0.354)

      7. Install the transfer dynamic damper.
