When I drive over about 50 MPH on a smooth road I feel a constant vibration. It's really annoying. The Tires are in balance too. I didn't really notice it before but I do now. The tires don't look bad but I don't know. They're the originals and I have 38,000 miles. Any ideas? I need to drive on the highway for close to an hour wednesday and the vibration is enough to make you sick to your stomach after a while.

A Hunter Road force balancing might help out. I doubt its the tires or alignment.
Start with good proper balancing. You state the balance is good, but unless its Road Force/Hunter it wont be proper.

The first thing that jumps to mind is uneven wear patterns (mentioned in the link you provided), which may or may not be obvious to the untrained eye. It's possible that the original owner never rotated the tires for 38k miles, but the dealership DID recently rotate them before selling. That could cause such a vibration for awhile, until the tread evens out properly.
The good news is that it's a cheap fix, since you can drive the problem away... but the bad news is that you'll have to put up with it for awhile to see if it indeed goes away.
This may be yet another issue to have the dealership check into, since they apparently did not mention this problem before selling you the Aurora.

I'm not so sure what this roadforce/hunter balancing is. is this something that a shop like discount tire could perform?

Here is the Hunter GSP9700 website that explains all the science behind it. Click on Locate a GSP9700 to enter your location and find the nearest shop with the right equipment. Apparently the Aurora suspension is complicated enough that it requires this process to properly balance it. Another good thing to check; I didn't see JimW's response before I posted mine about tire rotation.

I'm not so sure what this roadforce/hunter balancing is. is this something that a shop like discount tire could perform? In a nutshell, it can apply up to 1,000 lbs of rolling pressure to the tire while it spins. Thus you get a "true" balance of the tire under load instead of a balance of an unloaded tire. The Hunter balance will be much more accurate. I too would suggest this as a first step. And you might try asking the techs to get it as balanced as possible, even if it is within specs. I.e. it may be that they can make it more balanced but figure it's already good enough.

Due to the suspension setup the g-body platform cars are very sensitive to tire imbalance. A quick search on edmunds community forums yields quite a few posts on this subject, suggesting Goodyear tires to be the possible culprit as well.

I took it to discount tire today and he suggested that it was probably the good year tires. he said that they're a pretty crappy (as in cheap) tire. Apparently the stock tires are only rated at around 45,000 miles. He suggested that I go with some good Michelins after the goodyears are worn. According to him though I still have around 10,000 miles of usable tread so he didn't recommend getting new tires just yet. He did however say that I should put on my Yokohama snow tires and see if that makes a difference and to go from there. To get the Yokohamas installed would be $39 with balancing. Just to get a balance would be $60 using their advanced balancing machine. It's cheaper to get the Yokohamas installed and balanced only because I bought the tires from there so I get free mounting and discounted balancing.

I think the Goodyear RSA's on my 01 handle better than the Michelin MXV4's I have on my 97. I do agree with everyone else that the road force balance should fix your problem.

Goodyears the problem now great.....I have Eagle GT's and they handle really well. Where did you hear they get 45,000 miles? Mine are worn down pretty badly and theres only 2000 miles on them. I guess i spin to much maybe?

The Goodyear RS-A are a far softer tire then Michelin Energy MXV4 Pluses, I believe that is why the tread life is so much longer, the compound of rubber is fiercely strong. Most FWD owners with big torquey engines complain about tread wear but love the handling on the GY's and most owners with Michelins complain about bad handling but love good treadwear. Anyhow, not to get to off topic, start with the Road force
