regards my st navara D40 diesel manual rattle i have found it. what it is at about 1100 rpm at idle it has a very slight vibration must be torsional vibration maybe normal for a diesel ?? but as you keep revving it in neutral at about 1400 rpm the left front panel VIBRATES. Now how to fix it. I am going to see Nissan this morning to see what they say. I want to make sure the vibration is normal first but the only way to fix would be to spray FOAM, not sure i have not really had a good look. All i done is stuck a few pieces of cardbord inside the engine bay inbetween the joint and its much better allready but needs a permanent solution. Any IDEA has someone done it before with spray FOAM? Because the D40 has the flared guard all in one piece its quite a big section and has NO SUPPORT or INSULATION it VIBRATES on those RPM i mentioned. thanks
