Hyundai Tucson: Coupling Assembly- Installation
Hyundai Tucson - Fourth generation (NX4) - (2020-2023) - Workshop Manual / Wheel Drive (4WD) System / Coupling Assembly / Coupling Assembly- Installation
- To install, reverse the removal procedures.
WARNING
- Smear the splines (A) with molybdenum type high pressure grease.
- When install the coupling, be careful not to damage the oil
seal (B).
- After replacing the coupling, reset the 4WD ECU's clutch learing using
the diagnostic tool.
(Refer to 4WD Control System - "Repair procedures")
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. The torque to the rear wheels varies according to the pressure on the clutch.

Measuring the resistance of the pressure sensor
Turn ignition switch OFF.
Disconnect the pressure sensor connector.
Measure resistance between sensor terminal and terminal.
Check the measured resistance. (Refer to table)

Adjustment
Description
The friction material inside the coupling will degrade over time. Therefore,
corresponding compensation values must be referenced
and entered after replacing the controller or the coupling.

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