When driving at any speed get a howling noise, replaced rear wheel bearing and hub no change.
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.
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.)

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.

Did you check your Transmission fluid and your differential fluids make sure there up and I don't know if you checked your rear wheel bearings or not, You can usually tell a wheel bearing when you are driving the car at highway speeds and you go around a corner and it get quite a bit louder Depending on what way you are turning if your turning right and it gets louder it will usually be the right side front or rear. the left usually the left front or back. some cases I have even heard Axles making a Howling Noise. Please let me know what you come up with. And Thanks in advance If I helped you out any. Bear001

it sounds like you know what you are talking about so you probably already had a look inside the brake drum for worn shoes and broken springs ect.........If you haven't do so.As for the bearing.....there is one but it requires dis assembly of the reared.if you haven't done one of these,get someone who knows how to..there are too many little things to know and its easy to damage the diff from improper dis and re assembly(then you're lookin at big bucks) If you feel confident you can do this though get a step by step manual to ensure you know all of the procedures
hope this helps.........Good Luck!

I have a front wheel drive and at 120k I had noise in the back. It turned out to be a bad wheel bearing. It was tough to diagnosis because the quick check is to see if the wheel wobbles when pulled, but mine didn't. It wasn't untl they put it on a lift and found the wheel wouldn't roll freely.

You must replace wheel bearings in pairs to avoid loading the old bearing and, in time ruining your new bearing hub it is possible that you have already damaged the new hub

would need a drive to be honest to know exactly but it could be the windscreen seal they are stuck in and this could be a split in the bonding allowing air in hence the noise but i would need a drive to be sure
if you replaced rear axle bearings more likely your tires or road surface can cause noises while driving.
The is rhythmatic in nature kinda makes a um um um, not constant, wouldn't an axle or pinion shaft bearing make nose all the time?
if you hear whirring noise at low speed driving could be worn pinion bearing if you driving coasting or floating you could have worn ring gear or pinion gear.
