I drive a 2007 Corvette convertible which just rolled over to 13k miles. I am having continuing issues with what my service rep (who is a friend) calls the 'sway bars'. I put it in the shop months ago for a rattling type noise that I thought was then coming from the driver side front end. At that time they felt the noise was from the rear 'sway bar'. During that service visit they replaced the rear differential fluid with a newer 'whale oil' fluid and claimed give it about 800 miles to work the popping noise out. Well months later and I still hear the rattling noise in the driver side front and now the rear end is popping again. I just took it in again and went for a drive with my service rep who now does hear the front rattle and rear popping again. It's going back in the shop next week for them to check the sway bars out to see if they are possibly wearing down (which they shouldn't be). I asked what can be done and even though the sway bars can be replaced, Chevrolet doesn't recommend it. At this point, I'm truly concerned as it only has 13k miles on it. Has anybody had an issue like this?? Would you recommend keeping or ditching the car for another 2007, which is an option for me.
