PURPOSE: A tuning method for a hydro mount in a power train system is provided to set a maximum damping frequency band of the hydro mount by abstracting frequency arrangement of a bounce mode, a pitch mode and a standard mode of a suspension system and by coupling of the train system and the suspension system. CONSTITUTION: Maximum damping frequency bands of a bounce mode, a pitch mode of a power train system, and a hop mode and a tramp mode of a suspension system are abstracted by analyzing a vehicle system(S102,S102,S103). Coupling vibration frequency bands of the power train system with the suspension system is checked(S104). If vibration frequency bands of the power train system with the suspension system are coupled, the maximum damping frequency band of an engine mount is hydro mounted to the bounce mode of a power train and the maximum frequency band of a T/M mount is hydro mounted to the pitch mode of the power train(S105). If not, maximum frequency bands of the engine mount and the T/M mount are hydro mounted to the bounce mode of the power train(S106). A hydro mount tuning is applied to crosswise and lengthwise arrangements of the power train system. Therefore, riding comfort and stability are improved by tuning hydro mounts of the power train system and the suspension system to a specific maximum frequency band.
