2005 Chevy Avalanche V8 Four Wheel Drive Automatic 70k miles

we hear apulating noise when we put the truck in geaer and start to move forward, at around 15-20 kmh the noise is hear. THE repair tech said it's the front wheel hubs replaced and the problem is still there, one time we noticed the drivers side rear wheel was making an aweful grinding noise like it was a bad bearing when stopping. But of course it disappeared when checked out. There are no lights on the dash that indicate a problem. The techs are frustrated they can't determine the problem. Can a single rear sensor be the problem or could it be the pump and valve asssembly, any ideas for this 2005 avalanche problem. I have replaced the rear universal joint.

Hi:
can you better describe the noise? Does it change with speed or on turns?

Let me know.
