Could be a loose baffle in the muffler or Cat system - or two hundred other things - but check that out.

It is a known issue with Lexus that there is an annoying vibrating noise in all LX470s. However they will not do anything about it because they have determined it is "normal" noise found in all LX470s. I have been fighting with them for the past year because this is happening in my 2007 LX470. My noise occurs at idle and when I drive. Unfortunately the noise doesn't happen all the time. They have tried to fix it. I have told them the noise is still there, but they won't even take the car back to test drive it. And keeps telling me the noise is normal. I'm curious to see if others have had this problem.

i have a 2007 GX470 and i just took it to my lexus dealer for the weird noise and odd thumping at a stoplight or stop sign. Apparently they told me that there was a maintenance bulletin on this particular problem. they kept my car for 4-5 days and gave me a loaner while they waited for the part and fixed it. it was all under warranty.
also, i find it odd, but my GX470 appears to be off balance (i.e. the right side of the car appears to be higher than the left when looking at it from the back). Am i crazy? the dealer says that it is within manufacturer specification, blah, blah, blah. I was wondering if anyone else had this problem.

They keep telling me this is 'NORMAL' LX470 Noise as well, and i am baffled.
It stinks because this happens intermittently, and on occasion, 'idle' is smooth when i take it to Service, so they have nothing to diagnose.

Unfortunately you are probably stuck with your 2004 Lexus. I on the other
hand was protected under the Lemon Law and they repurchased it. I took a
loss because I decided not to go to court and fight them on it. They are
sending my vehicle to an auction and I feel bad for the poor soul who is
going to get it at the auction. Lexus is aware of this noise in the LX470.

I had the same problem with my GX 470. It sounded like a rattle. I took it to the dealer and they discovered there were loose wires in the dash. They went in the dash and tied everything up and I haven't heard the noise since. Have them check behind the glove box in the dash.
#18 of 21 thumping noise after the SUV made a complete stop at the light or stop sign

My Gx 470 is a 2008 and have 40k miles. I make a thumping noise after you make a complete stop at the light or sometime it make the thumping noise after you let the brake go and it does not does it all the time, I took it to the dealer and they said they known about the problem and nothing that they can do about it because it is a design problem and this is a big dealer in Houston. Is anyone out there have the answer?

I realize that this reply is being added 18 months since the thumping question was asked, but this answer may help others with what is known as "the GX470 Clunk".
Lexus issued a TSIB (Technical Service Information Bulletin) about the Clunk a long time ago--at least several years ago--and covers 2003-2008 models. The TSIB was updated to include some 2008 models in September, 2008--those with VINs less than JTJBT20X*80170241. The TSIB is # L-SB-0116-08.
Essentially, this TSIB authorizes Lexus dealers to replace the driveshaft with a new version of the driveshaft that does NOT clunk. The replacement will be done for free if your GX is still under the factory drivetrain warranty, which is 72 months or 70,000 miles. So, if your GX qualifies, call your Lexus dealer and get the free replacement driveshaft.
Our 2008 clunked a bit--not all the time--and we had ours done last week. Now there's no clunk at all!
If your GX is out of warranty, the clunk can be mitigated somewhat by greasing the zerts on the driveshart every couple of months--the grease seems to take up some of the "slop" in the driveshaft splines. Or, you can buy the new driveshaft for around $600 or so and have it installed or DIY. It's about a 20 minute job.

Thank you for your post. This is great tip. I just purchased a used 2004 GX470 with 102K miles with this clunky noise. I took to a mechanic and he said that all GX470 have or will have this issue. He suggested replacing bushings but he said it was not worth the effort. Where would one buy or ensures is buying the new driveshaft ? would this be a job one can do at home and if not, what is a reasonable fee to pay ?
