COUPLING COMPONENT REMOVAL/INSTALLATION


id031800155000

Oil and chemical type

Silicone sealant
 
Type: TB1217C or equivalent

Caution
•  If the characteristic value of a new coupling component is not input to the 4WD control module or the characteristic value is input incorrectly after replacing the coupling component, it could result in the following conditions:
―  The system does not operate normally.
―  A problem with durability of the coupling component occurs.
•  After replacing the coupling component, read out the characteristic value of a new coupling component and write it to the 4WD control module. (See COUPLING COMPONENT CALIBRATION DATA WRITING.)
•  Read out the characteristic value of the coupling component from the label or mark shown in the figure.

Note
•  The characteristic value of the coupling component before replacement is stored in the 4WD control module.
•  If the characteristic value of a new coupling component is not written, it is not stored in the 4WD control module.

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Drain the differential oil.

3.  Remove the following parts. (See FLOOR UNDER COVER REMOVAL/INSTALLATION.)

(1)  Floor under cover No.2
(2)  Floor under cover No.1

4.  Remove the fasteners in the order shown in the figure.

9.  Remove the propeller shaft. (See PROPELLER SHAFT REMOVAL/INSTALLATION.)

10.  Remove in the order shown in the figure.

11.  Install in the reverse order of removal.

12.  Add differential oil. (See DIFFERENTIAL OIL REPLACEMENT.)

13.  If the coupling component is replaced, write the characteristic value of the new coupling component to the 4WD control module. (See COUPLING COMPONENT CALIBRATION DATA WRITING.)

Coupling Component Removal Note

1.  Support the coupling component using a jack.

2.  Disconnect the coupling component using an oil pan seal cutter.

Coupling Component Installation Note

Note
•  Clean away the remaining silicone sealant before applying new silicone sealant.
•  Install the coupling component before the applied silicone sealant starts to harden.
•  Add rear differential oil after the silicone sealant hardens.

1.  Apply a thin layer of silicone sealant (TB1217C or equivalent) to the contact surfaces of the coupling component and the rear differential.

2.  Install the coupling component to the differential.
