I've been experiencing this annoying rattle coming from the front end. The rattle is not very loud and every time I drive over a bump, it sounds like I am driving over a Texas gate. I don't feel the rattle, but I hear it. It occurs only when I drive over a bump on the passenger side. No rattle occurs when I drive over a bump on the driver's side.

I have 3 questions:

1. Is it fair to rule out a bad engine mount?
2. Is it reasonable to pinpoint this to possibly a bad strut mount on the passenger side?
3. What are the impacts of driving 1700 miles until having this looked at? I have to go out of town next weekend. I called the Lexus dealership here at home and the earliest they can look at it is two weeks from now.

I am having my mechanic change the oil on Monday and will get him to look at it anyway, but I thought I would ask what everyone else's thoughts as to what may be the problem.

Thank you in advance for your help.
