looking for a little help. recently noticed a vibration at 75 to 80. it comes and goes at a steady speed . its more like a tremor that comes and goes, i feel it more in the seat than anywhere else . stock zo6 wheels. recently i changed wheels and tires and the tremor is still there and the same intensity . if i wasn't the first owner i might not notice but i do. any one have a similar issue? any help where to look , or what to check. thanks in advance Larry

Have a convertible by chance? I noticed same issue over 70mph. Its not bad. I just thought I may be getting some resistence from the soft top at that speed.

Had aligment and tires balanced by my buddy and chevy mechanic. He said both needed it bad. Its not real bad the vibration. First time corvette owner here, so i really don't know if this is normal or not. i do notice I feel every bump on the road. I have been driving in tour mode. I'm not going to do anything about it at this point. My buddy couldn't find a problem with the car. He looked over it pretty good. Be interested to see what these guys say about this on here.
98 Manual trans, convertible.

I have the exact issue. 03Z just hit 50K. Bought the car with 22K on it a little over 2 years ago. It had after market wheels on it but I have since changed those. Exact same speed range.Fell it more in the seat also. More annoying than bad. It acts like a tire out of balance but that can't be it. My thought was that it might be something else in the drive train slighty out of balance but that was just a hunch.

Its been there since I bought it. Did'nt notice it for a week or so. Balanced the tires several times(tires were Michelin pilots). Went to an 18/19 combo Michelin's again. Its like right at 80-82 but thats just happens to be normal interstate spped for me anything 2-3 mph higher or lower nothing. Like i said had 22203 on it when I bought it as of today 50044. Has not changed one bit. To be honest I hadn't really thought about it in a while until you started this thread

Asked about this a while back and didn't get much info except wheel bearings, balancing, bad tire, etc. 2 different sets of tires and wheels, new wheel bearings, balanced twice, wheel alignment and still has it. Not bad but noticeable. Some roads more than others and more at the start of a run and not as noticeable into the drive. The only thing I haven't did anything with is the torque tube bushings or rubbers. It is a convertible also but I do notice It with either the top up or down. Baffling thing. Getting used to it though I guess. Thanks

My guess would be a bent axle or bad cv joint.

My 09 vert had a strange vibration after changing wheels what I did was take the wheels off then spin them about 1/2 way.

It took out the vibration, the only thing I could think it could have been was a heavy spot on one of the rotors lining up with one on the wheel.

Having only 5 lugs I know there is no half way, but just moving the wheel might help.

Have you ever found the source of the problem? Mine is doing the same thing, the wheel bearings seem really good. Not sure where to look at this point.
