Car Forum / Chevrolet / Chevrolet Corvette / August 2006Popping Sound from 2000 C5
Hi Everybody, I hear a popping sound from my C5 as the car rolls slowly backwards or forwards. The popping happens whether the car is in gear or not, or whether the brakes are on or not. It seems to be coming from the rear of the car. At first I thought there might be something caught on a wheel, or a nail in a tire, but there isn't. The sound has no rhythm and occurs randomly. I can't seem to hear it while driving above a few miles an hour - even in a parking garage where it is easy to hear sounds bouncing off the walls. From what little I have been able to find via Google, it sounds like it might be a problem with a bearing. Any thoughts? Thanks, Matt Posted with NewzToolz. Free RAR, PAR, and yEnc decoders.

Matt, though I do not think it applies to Vettes (i.e. disc brakes), the last time I hear popping sounds like what you describe, my brake drums (Chevy Lumina) were oval (not round), so they had to be machined.

Hi Empty3, Yes, you are right, my Vette has all disk brakes. I noticed another detail: the popping sound only occurs when the car begins to move, wether forward or backward. So I start the car, shift into first or reverse, let out the clutch and then hear a popping sound or two and then no more as I continue to drive. I also tried turning off the engine while drivng so I could hear better. As the car coasted to a stop, there was no popping sound, so it is definately only as described above.

My vette only has half the milage than yours did, but I will check out the U-joints Thanks, Matt Posted with NewzToolz. Free RAR, PAR, and yEnc decoders. Get your free copy at www.techsono.com. I had a 2000 corvette did the same thing it is the propeller shaft sliding in when it starts to move. If you notice the body also moves up or down every so slightly when the car starts to move this is what causes the propeller shaft to slide.The propeller shaft connects the differential to the wheel. Its pops when there is torque on the shaft and it turns. It is not a problem and it will stop if you drive it offen. >Hi Everybody, > [quoted text clipped - 14 lines] >Posted with NewzToolz.
