REAR DIFFERENTIAL REMOVAL/INSTALLATION


id031400146400

Caution
•  Performing the following procedures could cause an open circuit in the rear ABS wheel-speed sensor wiring harness if it is pulled by mistake. Before servicing, disconnect the rear ABS wheel-speed sensor and set it aside so that the wiring harness will not be pulled by mistake.
•  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 4WD control module stores the characteristic value of the coupling component before replacement.
•  If the characteristic value of a new coupling component is not written, the 4WD control module does not store the value.

1.  Switch the ignition ON (engine off).

2.  Release the electric parking brake.

3.  Switch the ignition off.

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

Rear Differential Component Removal Note

Warning
•  Always verify that the rear differential component is securely supported by a jack. If the rear differential component falls off, it can cause serious injury or death, and damage to the vehicle.

1.  Support the rear differential using a jack.
