Mine always makes a rattling noise from the front, like something is loose, when going over the washboards going onto base. (I don't know what they're called but they're the grated bumps that make alot of noise when going over them) I have never worried about it since that is the only time it does it and they are pretty rough no matter how slow you go. Other than that it is quiet. I did have a squeeking/squaking noise from the front several months ago and it turned out to be bad struts from the factory but nothing ever sounded loose with that.
