Hyundai Tucson: Coupling Assembly- Removal

Hyundai Tucson - Fourth generation (NX4) - (2020-2023) - Workshop Manual / Wheel Drive (4WD) System / Coupling Assembly / Coupling Assembly- Removal



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, 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.
  • Always maintain a horizontal posture.
  1. Loosen the rear propeller shaft assembly mounting bolts and then removing the rear propeller shaft assembly (A).

Tightening torque : 49.0 - 68.6N.rn (5.0 - 7.0kgf.m, 36.2 - 50.61b-ft)

  1. Using a flat tool, separate the propellar shaft from 4WD coupling assembly.
  2. Disconnect the oil hydrulic motor connector (A).

  1. Disconnect the pressure sensor connector (A).

  1. 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)
