Incredibly annoying rattle from front end
I have taken it to the dealership and they claim they can't hear anything and I'll have to wait for it to get worse. The noise emanates from the front left wheel well area. It is only heard at low speeds (under 20-25mph) on areas of semi-rough or undulating pavement. It sounds like a loose shock or something....
I've seen on other boards that there have been problems with other Lexus vehicles and the struts, upper and lower insulators, mounts and bump stops...
Has anyone heard of this on the LS? It's making me crazy.

I am betting your brake pads are rattling in the caliper..there are anti rattle clips that could be missing...I had same exact condition..once the pads were more secured in the caliper..no mo rattle!
To test this, go to a rough pavement area where you can safely cruise at 15-25 mph with window down and listen for rattle..then slightly apply brakes to see if it goes away..if so...BAM!

Hopefully this is it, but if not, steering rack is a real possibility (depending on the year of your car).

I have a 2010.... My appointment is today. They "didn't hear anything" last time, but this time I'm not letting them get away with it.
between the rattle, and the loud POP from the undercarriage when the load shifts from side to side, I'm about to go nuts.

Final update: The inner tie rods were loose and causing the rattle. The power steering rack assembly (a 3 thousand dollar part) was replaced under warranty. The popping from under the car was from the under engine covers flexing. They were repositioned and secured and the noise seems to be gone.
Just glad it was all covered.

There are many suspension parts that Lexus has quietly redesigned on the LS460 (I know because my car has had all of them replaced), and I would imagine 2010 models already have most of the new stuff (some TSIBs I've seen stop at 2008 or 2009 models).
Glad it's all resolved. After my long laundry list of issues on the LS, I can confidently say that Lexus stands behind its product like no other manufacturer I've dealt with, as I've stated in other threads.

So much for the issue beng resolved. The noise from the front end persists even after replacement of the steering rack. I went back to the dealer this morning, and they want to replace the front left strut and (6)? control arms. At this point, they're waiting 24-36 hours for a factory rep to come and approve the repairs. The SA says if this doesn't resolve the issue, they'll have to get a field service rep out to look it over.
For a 2010 with 50K miles, this makes me worried about the long term prospects for this car. Sigh.
