What's that noise?
First, I must say I am very sensitive to noises, squeaks, and rattles. And typically discover things long before they actually need fixed. Since I've started putting miles on the GTS there is a noise that is getting louder. It is a speed dependent whirring like tire noise. I've change wheels and tires and the noise is still there. I've had an alignment done and the noise is still there. It starts at about 40 mph and increases frequency with speed. Taking curves, changing lanes, riding brakes, doing the F1 tire warm up zig zag does not change the noise. Wheel bearings feel tight trying to wiggle wheels with car on lift. From drivers seat it sounds like it is being transmitting into the cabin by the rear wheel well. From the passenger seat it sounds like it is coming from the whole right side of the car.
Wheel bearings, CV joints, Torque tube? Something else?

My '94 has had that same type of noise (if you come down to Austin for 3rd coast you can drive the '94 and listed to it) and I have guessed it is wheel bearings all along but have not done anything to it...15k miles later, no change, no problems... YMMV!

You could elevate the rear end off the ground and run it up to speed to try to locate the source.

One thing I've leart over time is that noises can travel in strange ways - they are not always where you suspect them. I had noises that I thought came from under my car, and were traced to my alternator. On my other car I had a noise that appeared to come from the bottom of the windshield, but it turned out to be a problem with the seal at the top.
If there is any way to simulate the noise with the car stationary, you could chase it with a vacuum cleaner hose (one end at your ear, the other where you suspect the noise. Bill has taught me the creative use of hoses for that purpose...
