Lexus LS 2007+ :: LS460L - Subtle Rattle In Rear Cabin Deck

2007 LS460L; nagging subtle muffled rattle in the rear cabin deck. It turns out that if you remove the passenger side panel in the trunk, whereas you are capable to reach behind the frame and the rear fender panel. There I found a drain hose, neatly wrapped in sound deadening material, but loose enough to rattle around against the outer rear fender panel enough to create that elusive subtle rattling sound.

I simply did a quick fastening job with gorilla "duct" tape, in order to secure the hose to the inner frame of the trunk. This prevents the hose from moving around with "ANY" movement produced by the vehicle over the smallest of bumps to the largest of bumps.

I checked everything from the sunshade, to the speakers, to the subwoofer, to the air ride suspension caps (accessed by removing my electronic reclining rear seats), to securing all hardware in the spare tire compartment, to the middle row seat belt "housing", to the middle row headrest "relaxed position", to the rear center console.

All of this effort only to read another members experience on their 2009 lexus is250 with the "brown/blue box electronic housing" in the trunk behind the panel on the passenger side, where he found his solution by tightening the retaining nuts on the housings bolts that secured it to the inner frame structure.
