Morning. I've got a 2006 Silverado 4x4 that has a noise which you can hear in the cab when going 10mph or slower. It almost sounds like a ball rolling around in something. It's not the steering shaft, I've replaced it plus it makes the noise going straight and turning. I've replaced the hubs and both CV axles, still hear it. It's not in the tires or hubcap. The front drive shaft doesn't have play in it. I seems to be in cadence with the rotation of the tires. As the truck slows the noise does. It's driving me nuts trying to figure out where it's coming from.
