Noise and vibration isolation - Toyota Mega Cruiser, 4.1 L, 1996

In mid-February, I gave the car to the AAS car studio in Juno.

Materials:
bimast bombs 20 sheets of
vitoplast 5 sheets of
visomat PB2 20 sheets of
vibroplast Gold 20 sheets

In addition, it was found that there is a double bottom (the meaning of which is unclear), with boiled screws, over the loosening of which they fought for two days.

(tomorrow I will post more pictures)
