Vibration from back?
In the market for a C4, my first Corvette. I test drove one today and there was some vibration that seemed to come from the back somewhere. Is it possible that a tire is just low? I guess there is an easy way to find out.

I bought one that had been curbed and ran like crap, after replacing the rims, tires and balancing it still had a little vibration, it was the rotors. They are pretty big and can cause vibration, but IMO opinion it might also be
Balance, alignment, tires, rims, suspension bushings, ball joints, bent frame, rear gear, half shafts, ujoints, wheel bearings, etc... whew!! did I get it all?
a thorough inspection is in order, as well as a good haggling job for any and all work required before you buy it.
could be something simple, but then again maybe not

While chasing down a vibration in the of my 95 I changed/checked a lot of things including:
Road force balance of rear tires
New shocks
Balanced the driveshaft and both half shafts
New u joints
It finally went away when I replaced the rear wheels
What made it tough to find was I had access to a hunter machine at work and the wheels and tires passed. I even spun the tires around on the rims IOT use the least amount of wieght
I even took the wheels / tires up the street to the nearest roadforce balancing place to have them done professionally (thought I may have been missing something) tech came out telling my he couldnt improve on how they were...
So long story short slight rim problems may cause a rear end vibration. Good news is once everything is perfect the vibration is GONE..
Good luck and happy hunting.
