6. LOOSEN REAR NO. 1 DIFFERENTIAL SUPPORT

HINT:

Loosen the bolts only when removal of the rear No. 1 differential support is required.

(a) Loosen the 2 bolts.

7. REMOVE REAR DIFFERENTIAL CARRIER ASSEMBLY

NOTICE:

  • Do not damage the contact surface when removing the rear differential carrier assembly.
  • The remaining oil may leak out when removing the rear differential carrier assembly.
  • Securely support the rear differential carrier assembly while performing this step to avoid excessively tilting or dropping the rear differential carrier assembly.
  • Remove the bolts and nuts with the rear differential carrier assembly secured.

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

(b) Support the rear differential carrier assembly with an engine lifter using 2 attachments or equivalent tools as shown in the illustration.

*b

Engine Lifter

(c) Remove the bolt (A) from the rear differential support.

(d) Remove the 2 bolts (B), and 2 rear lower differential mount stoppers from the rear No. 1 differential support.

(e) Remove the 2 bolts (C), 2 nuts from the rear No. 1 differential support.

HINT:

The nuts have tabs to prevent them from rotating.

(f) Disconnect the connector and disengage the clamp (A).
