I have a new LS430(17 inch wheels standard) with about 600 miles on it. Recently, I noticed at slow speeds over bumps or rough roads a faint kind of percolating or echoing noise on the left side of the car. It sound like it is coming from the front wheel area. Can only hear it inside, not outside and everything has to be off in the car to hear it. The car runs fine and doesn't exhibit any strange driving characteristics, just this slightly audible sound over bumps and rough road surfaces. Anyone have any ideas or is it just me being to fussy.

Thanks in advance for any comments.

I have a 2002 LS430 with 19,000 miles and never heard that weird noise. Take it to the nearest dealer and they will surely help you fix that.

I have the same car. LS430, 2003. I had a similar noise. Took it to the dealer and it turned out to be a loose bolt on an underneath metal panel. They tightened it, and no more noise. I bet your's is something similar.
