| Inspection |
All units are filled up with coupling fluid (ultra-low viscosity ATF)
prior to shipping. Inspection, fill-up, and replacement of coupling
fluid is therefore not necessary (zero maintenance, lifetime fluid).

Coupling Maintenance Precautions
Maintain the coupling at a horizontal level.
Refer to the handling caution level (A) when servicing the coupling
(removal, installation, replacement, etc.).
|
| 1. |
Remove the 4WD coupling assembly bolts (A) mounted to the rear propeller
shaft.
|
| 2. |
Using a flat tool, separate the propellar shaft from 4WD coupling assembly.
|
| 3. |
Disconnect the pressure sensor connector (A) and Oil hydraulic Motor
connector (B).
|
| 4. |
Loosen the coupling assembly mounting bolts (A).
|
| 5. |
Using a flat tool, separate the 4WD coupling assembly from the rear
differential carrier assembly.
|
| Installation |
| 1. |
Install in the reverse order of removal.
|
| 2. |
After replacing the coupling, reset the 4WD ECU's clutch learning using
the GDS tool.
(Refer to 4WD Control System - "Adjustment")
