Rear Differential Removal/Installation (Us): Notes

Oil and Chemical Type 

Sealant
Type: TB1217C or equivalent
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 PCM 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 PCM. (See COUPLING COMPONENT CALIBRATION DATA WRITING .)
  • Read out the characteristic value of the coupling component from the label or mark shown in the figure.
