Originally I thought I had a bad u joint but they all checked out. My noise, a thumping under acceleration occurs only when there is a load on the drive train. If I either let off the throttle or downshift it goes away. A fellow Corvete owner said it's probably the exhaust rubbing one of the half shafts or drive shaft. I haven't examined the pipes since learning this. Just wondering if anyone else has expierenced this and knows how to fix it? It's the stock exhaust I think. That's what this forums for, right?
