Hyundai Santa Fe: Coupling Assembly / Direct Electro Hydraulic Actuator Coupling. Repair procedures
| •
|
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.).
|
| •
|
Always maintain a horizontal posture.
|
|
| •
|
Be careful not to damage the parts located under the vehicle
(floor under cover, fuel filter, fuel tank and canister) when
raising the vehicle using the lift.
(Refer to General Information - "Lift and Support Points")
|

|
1. |
Loosen the rear propeller shaft assembly mounting bolts and then removing
the rear propeller shaft assembly (A).
|
Tightening torque :
49.0 - 68.6N.m (5.0 - 7.0kgf.m, 36.2 - 50.6lb-ft)
|
|
|
2. |
Using a flat tool, separate the propellar shaft from 4WD coupling assembly.
|
|
3. |
Disconnect the oil hydrulic motor connector (A).
|
|
4. |
Disconnect the pressure sensor connector (A).
|
|
5. |
Loosen the bolts and then removing the coupling assembly (A).
|
Tightening torque :
58.9 - 64.7 N.m (5.8 - 6.6kgf.m, 41.9 - 47.7 lb-ft)
|
|
|
1. |
To install, reverse the removal procedures.
|
• |
Smear the splines (A) with molybdenum type high pressure
grease.
|
|
• |
When install the coupling, be careful not to damage
the oil seal (B).
|
|
|
|
2. |
After replacing the coupling, reset the 4WD ECU's clutch learing using
the diagnostic tool.
(Refer to 4WD Control System - "Repair procedures")

Description
4WD ECU processes signals from various sensors and determines the current road
and driving conditions. The ECU then utilizes this information to implement
precision control over the 4WD coupling's multi-plate clutch and variably adjust
the amount of torque delivered tothe rear wheels...
Description
The 4WD ECM controls the Pump Motor Pump (Actuator) to generating an oil pressure.
The pressure engages a multiple disk clutch to transfer torque to the rear wheels...
Other information:
Reverse Parking Distance Warning will help warn the driver if an obstacle is
detected within a certain distance when the vehicle is moving in reverse at low
speeds.
Detecting sensor
[1] : Rear ultrasonic sensors
Refer to the picture above for the detailed location of the detecting sensors...
Before driving your vehicle, check to see that your inside rearview mirror is
properly positioned. Adjust the rearview mirror so that the view through the rear
window is properly centered.
WARNING
Make sure your line of sight is not obstructed. Do not place objects in the
rear seat, cargo area, or behind the rear headrests which could interfere with your
vision through the rear window...
