Tire noise, maybe not...

I have been having what I thought was tire noise for about the last month. I had crappy tires that were worn uneven so I thought that it was a no brainer, I need new tires.
Well $500 later and the noise is still there. No change.
It is worst at 40-50mph but it starts at about 15mph and it is still very noticable at 70mph. It is so loud at 45 that I have to cover my ears.

Any ideas on what could be causing this?

how does this noise sound in your own words.

Could be a wheel bearing.

It's kind of tough to describe. It sounds like I'm driving around in a Jeep with 33" mudders. But it gets real bassy around 45mph. And I'm talking LOUD, like I'm sitting on a speaker at a Pantera show or something.

I'm going to bite the bullet and take it to the dealer on Monday. $$$, but oh well. The thing has 155,000 miles on it and I have only had to take it to the shop one other time. Not too bad.

alighnment maybe? ...Maybe your shocks are bad and affecting the ride hight and tire wear.

it was the right front hub assembly. $400 ouch!!!

how did they figure out which wheel had the problem? i have a slight whine sometimes. wondered if it was the tires on road, but always interested in another theory.

I think you can hear it if you have the car on a jack and spin the wheel by hand. You probably have to get it spinning pretty quikly but that should do it.
