I'd bet money its the front strut assembly. What you are describing is exactly the problem I was having...drove me absolutely nuts...then the big wigs on UY told me to check the front strut assemblies and bingo.

The three bolts that get fed through the top of the tower will sometimes work themselves loose in the top plate of the strut/coil assembly. There are threads at the base of the bolts, those threads get worn which cause them not to seat properly, thus they don't tighten properly,...thus you get the rattle when you hit the bump. Its mostly likely just one bolt that is causing it. I found my bad one when I tried to take the strut assembly out, the nut got hung up on a rusty part and when I turned it the whole bolt would turn because the threads weren't grabbing...i finally cut it off with a dremel and replaced the bolts and top plate.

Hope this makes sense...give it a try..i bet you'll fix it....let me know if you have questions.
