When I first got the VX, my dad in law checked it out. He noticed that the hood hinges needed a little bit of WD40 sprayed on them. I had'nt thought anything else about it until today.
Maybe the hood is in a bind causing it to make a noise on a little bit of ruff ground. I am going to spray it in the morning and see if that takes care of the problem. If not, I will let the ZuZu boys take care of it next week.
