I agree - My Base model has a great ride.

To be fair, SecPole14's comment that this is another reason to avoid AVS/air suspension is bogus. There doesn't seem to be a lot of issues with the GX's air suspension with the exception of some on the 470 after a long period of time which makes sense since shocks don't last forever. I have seen no issues on the GX460 yet here. If we were talking about the LS suspension the argument would make more sense since there are failures with the air suspension in that car with low miles.

I had a similar rattle on my 2010 GX 460 lux and for me it was a simple solution. I found the jack in the cargo area door panel was being held in by an elastic ban. When I hit some bumps the jack would rattle. To resolve this I actually turned the jack **** with my finger to raise the jack so it would contact the top of the jack holder so it pressed itself in place. No more rattle. Just finger tighten the screw so if you need the jack just loosen and remove. I hope this solves your issue.

Lolrax, I agree, check your jack and tools and make sure they are securely in place. Also, easy to overlook is your spare tire. Make sure that it is cranked up and tight up against the bottom of the vehicle. Your owners' manual shows you how/where to crank up and down your spare.

You guys nailed it, the jack was not held in place by anything and was actually just rattling around completely free in there. I feel like a dope for making such an issue out of something so small now! haha. I feel its a bit clunky but man is it better. Thanks again guys.

The Lexus dealership turned me away saying it was the spare tire and never responded to another email I sent to the service manager about it so I made some calls and a Toyota dealership in town is going to take a look. The Sequoia has a similar system, so hopefully we can get an answer here.
Every time I hit a bump I wince.

Lolrax, have you've tried just bouncing up and down with the GX while it's in park to see if there is something more discernible about the noise?
Or even trying to just drive it over speedbumps?
By the way, I'm not sure about the design on the GX, however when I had my Grand Cherokee, the front brake calipers used a sleeving design, once the sleeves wore out, it caused the calipers to clunk going over small bumps (here's a link to the sleeves) http://www.thephantum.jeephorizons.c...ob/sleeve2.jpg I replaced the sleeves and clunking went away.
Now that I look at the diagram on sewell, it looks like there might be a similar part. http://lexus.sewellparts.com/images/...000/477101.jpg
There might a couple of diagnostics things you can do, try going over speed bumps with the brakes feathered, going over them with the parking brake slightly engaged. Checking to see if any of it has an effect on the sound.
Just throwing out some ideas. I hope it helps. I just had my GX for a little over a week...complete newb to this vehicle but I've been working on cars for a long time.

Thanks for the suggestions! I tried both of those today and couldn't replicate the sounds. I really got it rockin when I was in the cargo area jumping around too the only clue is that the sound is lesser when I switch from comfort to sport mode with my adjustable suspension. Could the shocks be bad?
