That could be anything from tires to differential or even a driveshaft carrier bearing on your Vette. The best thing to do is to see if it will make the noise while running it on a lift. If it does not, then the noise is most likely tire-related. If it does, then you can use a mechanic's stethescope to determine the source of the noise.
I replace axle bearings all the time that make rythmic noises. There are some that make one long, continuous growling noise, but MOST of them start out as one or two of the bearings getting pits in them that cause a rythmic noise. However, bad tires can sound just like a bad wheel bearing. I have had many that I could not tell the difference (wheel bearing or tire) by driving the vehicle. A bad pinion or carrier bearing or chipped gears in the differential can make some of these same types of noises. Some noises can be exteremely difficult to diagnose if the correct methods are not used.I replace axle bearings all the time that make rythmic noises.

Hey Dennis, you may just have only 1 bad tire. You can verify that it is a tire by rotating the tires one side at a time to locate your problem-child. Rotate one side. If the noise moves, you know that the bad tire is now on the front wheel on the side you just rotated. If you rotate all tires and the noise remains the same, then you must look elsewhere for the noise. (This is assuming that all of your wheels are the same...I know this is not always true for some Vettes.)Hey Dennis, you may just have only 1 bad tire.

Well,the pinion bearing at the rear end could have a bad preload adjustment.OR something inside the rear end(differential) could be loose or worn. The fluid level is okay, I take it? don-ohio (:^)
Yes fluid is full. It is not rear gear noise, I think the tires are likely the cause. Thanks for the input guys, tires are very expensive for this car, so didn't want to replace them unless I was fairly sure it was the noise problem. I can't feel any play in the wheel bearings which is the common symptom for noisy bearings in the car.Yes fluid is full. It is not rear gear noise, I think the tires are likely the cause.
