  5. LOOSEN NO. 2 REAR DIFFERENTIAL SUPPORT

    Tech Tips

    Loosen the bolts only when removal of the No. 2 rear differential support is required.


    1. B007YYD

      Loosen the 2 bolts.

  6. REMOVE REAR DIFFERENTIAL CARRIER ASSEMBLY WITH DIFFERENTIAL SUPPORT

    Note


    • Do not damage the contact surface when removing the rear differential carrier assembly with differential support.

    • The remaining oil may leak out when removing the rear differential carrier assembly with differential support.

    • Securely support the rear differential carrier assembly with differential support while performing this step to avoid excessively tilting or dropping the rear differential carrier assembly with differential support.

    • Remove the bolts and nuts with the rear differential carrier assembly with differential support secured.


    1. B007Z1H

      Disconnect the vacuum hose from the electro magnetic control coupling sub-assembly.

    2. B007YNDC02
      *A 8AR-FTS
      *1 Lower Rear Differential Mount Stopper
      *a Attachment
      *b Engine Lifter

      Support the rear differential carrier assembly with differential support with an engine lifter using 3 attachments or equivalent tools as shown in the illustration.

    3. for 8AR-FTS:


      1. Remove the 2 bolts (A) and rear differential dynamic damper from the differential support.

    4. for 2GR-FKS:


      1. Remove the 2 bolts (B).

    5. Remove the 2 bolts (C), 2 nuts and 2 lower rear differential mount stoppers from the No. 2 rear differential support.

      Tech Tips

      The nuts have tabs to prevent them from rotating.

    6. B007ZXGC02
      *1 Vacuum Hose
      *a Clamp (A)
      *b Clamp (B)

      Disconnect the connector and disengage the clamp (A).

    7. Separate the vacuum hose from the clamp (B).

    8. B007WMFC02
      *1 Vacuum Hose

      Slightly lower the rear differential carrier assembly with differential support, remove the vacuum hose from the clamp.

      Note

      Do not damage the vacuum hose and electro magnetic control coupling wire harness.

      Tech Tips

      Lower the engine lifter to the extent that the vacuum hose can still be removed.

    9. Lower the rear differential carrier assembly with differential support slowly to remove the rear differential carrier assembly with differential support.

      Note


      • Do not damage the vacuum hose and electro magnetic control coupling wire harness.

      • Move the engine lifter forward and backward as necessary to prevent the rear differential carrier assembly with differential support from contacting the rear suspension member sub-assembly.

  7. REMOVE DIFFERENTIAL SUPPORT


    1. B007ZOJ

      Remove the 3 bolts and differential support from the rear differential carrier assembly.

  8. REMOVE UPPER REAR DIFFERENTIAL MOUNT STOPPER


    1. B007YCV

      Remove the 2 upper rear differential mount stoppers from the No. 2 rear differential support.

  9. REMOVE NO. 2 REAR DIFFERENTIAL SUPPORT


    1. B008008

      Remove the 2 bolts, 2 nuts and No. 2 rear differential support.

      Tech Tips

      The nuts have tabs to prevent them from rotating.
