Hydropump Galant 2,5 V6

Hi, I drive a Galant 2.5 V6 Avance Built 10.2000. Got 70 Tkm on it now and can hardly believe it. The hydro-pumps start already violently loud to clapping. Strangely only occasionally. 4 days is fine and then you think again the engine gives up soon. My last Galant also has a little clapping, but he had already over 200 Tkm on it. That can’t be true !!! Does anyone have experience with it? For possible purposes cost a repair, or whether a direct vehicle r for the engine. Mfg GizmoK
