Our Tahoe's drive shaft has been making a noise for a while. The noise happens usually at slow speeds. Best example is when you are in a drive through, that speed level. But it can also happen if you are sitting still.

So, I had my wife rev the engine and I got under the Tahoe and I am 98% sure it is coming right from within the drive shaft and as she revved the engine, the noise was happening. Sounds like a clanging noise that accelerates as the gas is pressed.

Anyone have anything similar?

Thanks very much!
