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.
-
• 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.

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.
2. Loosen the differential mounting bracket bolt and rotate the bracket as shown in the figure.
3. Rotate the rear differential as shown in the figure, and then remove the rear differential.
Rear Differential Mounting Bracket Installation Note
-
Caution
-
• Retighten the rear differential mounting bracket stud bolt when the rear differential mounting bracket nut is loosened.
1. Tighten the rear differential mounting bracket stud bolt.
