chdbgroup,
If you can kick the tire and hear the same noise you might have a serious problem.
I'd suggest getting the car on jackstands. Then there's no load on the suspension and you should be able to wiggle things to your heart's delight to see what's making the noise. Check the tie rod ends, steering and suspension components.
What did the dealer do at the 30k mile service? Anything steering or suspension related?
In any case, 37k miles is nothing on a Honda...I don't know the Odysseys, but I'd say it's too early for any suspension noise.
If you don't have a hydraulic jack and jackstands, I'd suggest getting to a mechanic ASAP as you shouldn't hear any noise when you kick the tire...something might be very loose.
