Hyundai Tucson: Coupling Assembly / Direct Electro Hydraulic Actuator Coupling Repair procedures
| Inspection |
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).
