For the amount of utility and gizmos in the LR3, I am surprised that it does not rattle much at all. Coming from an Audi A6 4.2 which did not rattle at all, the LR3 only has slightly more noises.
Ensure all things are snug in all cubbies. My biggest rattle which drove me nuts for two days, turned out to be the chest buckle on my child's car seat. I have to keep it buckled. Also check the that the tow bar is not making the rattle in its storage cubby. Remove it, and driver for a while.
Frankly, if I have any kind of rattle, it bugs me. So far, 2,100 miles, I am a-ok. Of course, I just have to get the speaker rattles to go away. . .
