My wife drives a 2003 GMC Envoy and has been complaining about this same creaking noise upon breaking or going over speed humps. I researched this topic on the internet high and low and tried everything I read to no avail. I was about to give up and then realized it could be the motor mounts since when you break or go over bumps the engine does have some movement. Sprayed the most interesting looking motor mounts I've ever seen with silicone spray and the noise was gone! My wife has been complaining for years about this noise and now looking back what a simple solution!. By the way my motor mounts where not worn out, the rubber portion of the mount just needed a little lube.
Could be the suspension or shocks ( ? ).

I had asked the repair technician to replace the stabilizer bar, but he insisted that that was not the problem. I am going to be taking it to a different dealer soon and I will ask them to check the suspension, the stabilizer bar and the struts.
yes -- I would try a different dealer ( or a independent mechanic that deals with suspension/shocks and struts ). I found a noise problem on my friends truck and it turned out to be a loose shock nut,, I am not saying that that is the problem, but from your description it sounds like a suspension issue.
good luck and have a happy New Year ( !!! ).
