Rear Differential Removal/Installation: Notes

WARNING: This page is about a different variant/trim than selected.

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 AWD control module or the characteristic value is input incorrectly after replacing the coupling component, it could result in the following conditions:

After replacing the coupling component, read out the characteristic value of a new coupling component and write it to the AWD 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 AWD 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 AWD control module does not store the value.

Drain the differential oil from the rear differential. (See DIFFERENTIAL OIL REPLACEMENT .)
Remove the TWC. (See EXHAUST SYSTEM REMOVAL/INSTALLATION [SKYACTIV-G 2.0] .)
Disconnect the propeller shaft from the rear differential. (See PROPELLER SHAFT REMOVAL/INSTALLATION .)
Suspend the propeller shaft using a cable as shown in the figure.
