|1.||Make sure you have the anti-theft codes for the radio, then write down the audio presets.|
|2.||Make sure the ignition switch is OFF, then disconnect the negative cable from the battery.|
|3.||Disconnect the torque sensor 4P connector (A), motor-angle sensor 6P connector (B), motor 1P connector (C) and motor 2P connector (D).|
|4.||Remove the connectors (E) from the left side of the steering gearbox connector bracket (F), then remove the harness clip (G).|
|5.||Remove the harness clips (A) from the harness clamp bracket.|
|6.||Disconnect the torque sensor 3P connector (A) from the steering gearbox, then remove the harness clamp bolts and ground terminal (B).|

|1.||Clean the mating surface of the motor (A) and steering gearbox.|
|2.||Apply a thin coat of silicone grease to the new O-ring (B), and carefully fit it on the motor.|
|3.||Apply silicone grease into the motor shaft (C).|
|4.||Install the motor on the steering gearbox by engaging the motor shaft and worm shaft (D).|
|5.||Before tightening the bolts, turn the motor two or three times right and left about 45 degrees. Make sure the motor is evenly seated on the steering gearbox, and that the O-ring is not pinched between the mating surfaces.|
|6.||Connect the torque sensor 3P connector (A) to the steering gearbox, then install the harness clamp bolts and ground terminal (B).|
|7.||Install the harness clips (A) to the harness clamp bracket.|
|8.||Install the torque sensor 4P connector (A), motor-angle sensor 6P connector (B), motor 1P connector (C) and motor 2P connector (D) on the left side of the steering gearbox connector bracket (E).|
|9.||Install the harness clip (F), then connect the steering gearbox connectors (G) to the steering gearbox.|
NOTE: Make sure to push these connectors until you hear a click so that the connector are secured.
|10.||Finish the installation, and note these items:|
