Dismantling
1. Place the vehicle on a lift and select a low gear in the transfer case (Low Range).
2. Turn off the ignition.
3. With the automatic transmission selector in neutral, make sure there is no fuse installed in slot 37 of the main fuse box. If there is a fuse, remove it.
4. Raise the car on a lift.
5. Clean the disassembly area from dirt.
6. Install a container to collect the leaking working fluid.
7. Turn the shoe counterclockwise to release it and remove it from the gear ratio control actuator connector.
8. Remove the three screws securing the actuator to the transfer case.
9. Do not dislodge the drive screw, which should remain in the transfer case. Very carefully and slowly separate the ratio control drive assembly from the transfer case. Use a small flat-blade screwdriver to prevent the drive screw from moving with the drive assembly, as shown in the illustration. CAUTION: If the drive screw turns or is pulled out with the drive, damage to the transfer case mechanism may result.
