Help Me Diagnose a Problem...
For a little while now I've had a noise I can't ignore anymore coming from the back end of the 98. It sounds like it comes from the right rear, and it sounds like tire noise... like I'm running mud terrains or something. Only noticeable at speeds over 40. It increases in pitch as I go faster. As I turn the car back and forth on the highway as if I'm warming up the tires, it only makes the noise when the weight of the car is on the left side. So, no weight on right side... right rear makes the noise. This make sense? Any ideas? Bad bearing? What the dealio?

What kind of tires are you running? And what is the condition of the tires - how many miles are on them?

I wish like heck it was a tire issue like some of you guys suggest but the Kumho's only have like 25K on them, and they look just fine. If in fact we are looking at a shot wheel bearing, how much cash we talkin? Easy fix?

Not much, you can do it yourself...

I got my rear bearing with hub (came as a unit) for around $300- 320 at the dealer. Put it in myself. It wasnt that bad. I cant see it being more than 2 hours labor at a shop. Ahhhhh, the sound of silence.

Classic case of bad wheel bearing... had the EXACT same symptoms on mine. When you unload the bearing the nosie goes away. So if when you slalom to the right (weight loads to the left side) the bearing is quiet.
Do yourself a favor... Autozone carries Tilden (sp?) brand hub/bearing assemblies for the car. They are the SAME part used in the oem application and are under $200 each vs. almost $400 from the dealer. The install isn't too bad.
I track my car so I replaced my fronts at 55k as they got a little vertical play in them, and my RR went bad a few years back and that's when I got the roaring that would go away when I'd slalom the car.

Looks like I've got a diagnosis... I love this corvetteforum stuff! I'm going to check into getting the part and tackling it myself... sounds like fun. I'll let you all know how it goes. Thanks again!

mine did the same thing but at low speeds and when turning. it was the rear end, but nothing bad it was the limited slip and i added some limited slip addative from gm when i changed the rear end dope and everything was much better. try it out befor you replace wheel bearings, should be much easier and cheaper for ya, and provably needs to be done anyways.
