Default Severe Front End "Clunk"

I have a 2008 Z51 6MT car with 29K miles.

Out of nowhere yesterday, while pulling away from a stoplight, I started getting a metallic clunking noise coming from the front end of the car. Almost feels like something is hitting the floorboard.

I jacked up the car and had a look and everything seemed ok. Then I drove it to a repair shop - clunking all the way - and left it with the mechanic. He only had a short time to look at it today, as he left town at lunch and will continue to diagnose the car on Monday.

It almost sounds like the subframe is loose, although he said everything under the car looks good.

Oh, and the noise happens only when the car is in motion, doesn't matter whether the driveline is loaded or not. It does not make noise while stationary and brake-torquing the drivetrain.

Any thoughts or ideas are much appreciated...Thanks!

The car is locked up in the repair shop for the weekend and can't help but try to narrow down the cause.

Does this sound like a busted motor mount to anyone has had one fail?
