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:
All tire pressures (including the spare) should be checked when the tires are
cold. “Cold tires” means the vehicle has not been driven for at least three hours
or driven less than 1 mile (1.6km).
Warm tires normally exceed recommended cold tire pressures by 4 to 6 psi (28
to 41 kPa)...
Release Residual Pressure
in Fuel Line
•
There may be some residual pressure even after "Release Residual
Pressure in Fuel Line" work, so cover the hose connection with
a shop towel to prevent residual fuel from spilling out before
disconnecting any fuel connection...
