Dealer Checked my Hummer. They said all H3's have the same problem

Drivetrain issue? What does that mean?
What is drivetrain? Should I trade in
my H3 if that is the case?

If all hummers do this then mine must suck because mine doesnt rattle. I guess I need to take mine back to the dealership and bitch to them about mine not rattling enough!

I mean it's not THAT noisy, but you
can hear the engine stressed out especially
when you go uphill.

The drivetrain is located directly below the muffler bearings
